Why Your Karate Kata Lacks Practical Power (And How Cedarzz Restores It)

Why Your Kata Feels Weak: The Hidden Disconnect Between Form and Function

You have practiced the same kata hundreds of times. Your stances are low, your punches snap, and you can perform the entire sequence from memory without hesitation. Yet when you try to apply those techniques in sparring or self-defense drills, something feels off. The same powerful strike that breaks boards in the dojo lands with a thud against a resisting opponent. Your blocks, crisp in the air, collapse under even moderate pressure. This gap—between the beauty of kata performance and the gritty reality of combat—is not your fault. It stems from deeply ingrained training habits that prioritize aesthetics over biomechanics.

The Aesthetic Trap: How Perfectionism Robs Your Power

Traditional kata instruction often focuses on external form: the exact angle of the foot, the height of the fist, the rhythm of the movements. While precision has its place, many practitioners fall into what we call the aesthetic trap—optimizing for visual perfection rather than functional efficiency. When you drill a punch to stop exactly at the centerline with a locked elbow, you are training for a static display, not for impact. Under real conditions, your body needs to generate force through the entire kinetic chain: legs drive, hips rotate, core stabilizes, and the arm remains relaxed until the moment of contact. By fixing the arm too early, you cut off the transfer of power from your lower body. This mistake is especially common in kata where the performer can see their own reflection in a mirror or the judgmental eyes of an examiner. The result is a movement that looks correct but lacks the explosive follow-through needed to penetrate a target.

The Breathing Disconnect: Why Gasps Sabotage Impact

Another hidden culprit is improper breathing. Many kata systems teach a sharp kiai at the end of a technique, but neglect the inhale-exhale pattern that sets up each movement. In practical combat, your body needs a stable core to absorb incoming force and generate outgoing power. If you hold your breath or take shallow chest breaths during a sequence, your intra-abdominal pressure drops, destabilizing your spine and weakening your strikes. I have observed practitioners who, in an effort to look dynamic, speed through transitions while gasping for air. This creates a rhythm that is disconnected from the body's natural power generation. To restore practical power, you must learn to breathe deeply into your diaphragm, exhaling sharply on every explosive technique and inhaling during the preparatory movements. This is not just a relaxation technique—it is a mechanical necessity for force production.

The Cedarzz Perspective: Power Is a System, Not a Pose

Cedarzz approaches this problem by treating the body as an interconnected system. Instead of isolating kata into separate moves, Cedarzz analyzes the biomechanical chain behind each technique. For example, a simple front stance punch involves ground reaction force from the rear foot, torque from the hip rotation, bracing from the core, and a whipping action from the shoulder. If any link in that chain is weak or misaligned, the power leaks. The Cedarzz restoration process begins with a diagnostic phase where practitioners perform their kata in slow motion while a coach observes key indicators: foot pressure distribution, hip timing, shoulder tension, and breath pattern. Common findings include practitioners who rotate their hips too early (before the foot is planted), who lock their shoulder before impact, or who exhale after the strike lands rather than during the millisecond of contact. These subtle timing errors can reduce impact force by 30-50% according to informal measurements in our training groups. By correcting these micro-mistakes, Cedarzz helps practitioners recover the natural power that traditional training often suppresses.

This overview reflects widely shared professional practices as of May 2026; verify critical details against current official guidance where applicable.

The Core Frameworks: Understanding Force Generation, Structure, and Timing

To restore practical power to your kata, you must first understand the three pillars that underpin every effective technique: force generation, structural integrity, and temporal precision. These frameworks are not new—they are borrowed from physics, biomechanics, and sports science—but they are rarely taught explicitly in traditional karate settings. Once you internalize them, you can diagnose why a particular movement fails and design targeted corrections. Let us explore each framework in depth.

Force Generation: The Ground Reaction Chain

Every powerful strike begins with the ground. When you push off the floor, an equal and opposite reaction force travels up through your leg, hip, and torso into your striking limb. This is called ground reaction force, and it is the primary source of power in any weight-bearing technique. In kata, many practitioners lose this force because they do not fully transfer their weight. For example, in a typical zenkutsu-dachi punch, the rear leg should drive the hip forward, not just straighten the knee. If you focus on straightening the knee without pushing the hip, you generate less than half the potential force. Cedarzz drills this by having practitioners practice the hip thrust in isolation—standing on one leg and driving the hip forward while keeping the upper body relaxed. Only after the hip movement is automatic do they add the arm. This decomposition prevents the common error of using shoulder strength to compensate for a weak hip drive.

Structural Integrity: The Role of Alignment and Tension

Even if you generate ample force, you need a stable structure to transmit it to the target. Structural integrity means that your joints are aligned properly to resist deformation upon impact. In kata, blocks are particularly vulnerable to structural collapse. A rising block (age-uke) that uses only the arm, with the shoulder shrugged and the elbow bent, will shatter under a heavy downward strike. The correct structure involves the entire arm forming a rigid arch, with the shoulder depressed and the scapula retracted. Cedarzz uses a simple test: have a partner push down on your rising block while you hold it. If your arm collapses or your shoulder rises, your structure is weak. The fix is not to strengthen the arm but to engage the latissimus dorsi and lower trapezius muscles to lock the shoulder in place. This creates a tensile strength that can redirect force rather than absorb it.

Temporal Precision: The Power Window

Timing is often reduced to rhythm, but in practical combat, it is about the precise moment when your body's kinetic chain is synchronized. The power window is the split second when your hip rotation, foot plant, and arm extension all peak simultaneously. In most kata performances, these events are slightly staggered—the hip rotates before the foot is planted, or the arm extends after the hip has stopped. This misalignment dissipates energy into your own muscles rather than into the opponent. To train temporal precision, Cedarzz uses a method called slow-resistance-slow: first, perform the technique at one-tenth speed while focusing on the order of events; then, add resistance (a partner pushing against your movement) to force the body to coordinate; finally, return to slow speed to reinforce the corrected pattern. This three-step cycle reprograms the nervous system to fire muscles in the correct sequence automatically. Without this temporal refinement, even the strongest athlete will produce weak strikes in dynamic situations.

By mastering these three frameworks, you move beyond copying external shapes and begin building techniques from the inside out. The next section will show you how to apply these principles in a repeatable training workflow.

Execution: A Step-by-Step Training Workflow to Restore Power

Theory without practice is hollow. This section provides a concrete, repeatable training workflow that you can use to systematically restore practical power to any kata. The workflow is divided into four phases: diagnostic, decomposition, integration, and pressure testing. Each phase builds on the previous one, ensuring that corrections stick before you add complexity. Plan to spend at least two weeks per phase before moving on, depending on your current skill level.

Phase 1: Diagnostic Slow Motion Recording

Begin by recording yourself performing your kata at full speed, then at half speed, then at one-quarter speed. Use a smartphone or camera from the front and side angles. As you watch the playback, look for three specific red flags: (1) any hesitation between movements (indicates lack of connection), (2) any visible flinch or tension in the face (indicates holding breath), and (3) any wobble in the stance during transitions (indicates poor weight transfer). Create a checklist of the top three issues you observe. For example, you might notice that your hip rotation always starts before your front foot is planted, or that your shoulders rise during blocks. These observations will guide your corrections in the next phase. Do not try to fix everything at once—focus on the most impactful flaw first.

Phase 2: Decomposition Drills

Once you have identified your primary weakness, isolate that component from the full kata. For instance, if your hip rotation is mistimed, practice only the hip thrust from a stationary stance for 100 repetitions per session. Cedarzz recommends using a resistance band around your hips to create sensory feedback: the band should remain taut through the entire rotation, indicating continuous tension. Do not add the arm until you can perform the hip movement smoothly and consistently. This decomposition prevents the brain from falling back into old habits. Similarly, if your breathing is off, practice the kata's breathing pattern while sitting still: inhale for two counts, then exhale sharply for one count, repeating until it feels natural. Only then add the movement. Decomposition may feel tedious, but it is the fastest route to rewiring deep motor patterns.

Phase 3: Integration with Progressive Overload

After each component is individually corrected, begin reintegrating them in small segments. Start with three consecutive movements from the kata, performed at half speed while maintaining all corrections. Gradually increase speed by 10% per session, but only if the technique remains clean. Use a metronome app to ensure consistent rhythm—a common mistake is to speed up in bursts, which reintroduces timing errors. Cedarzz suggests using a heavy bag or a partner with focus mitts during this phase so you can feel the impact. If the impact feels weak or your hand bounces off the bag, your structure or timing is still off. Go back to decomposition for that specific technique. This integration phase typically takes one to two weeks per kata section.

Phase 4: Pressure Testing in Dynamic Drills

The final phase is to apply your corrected kata techniques in unpredictable scenarios. Start with a partner who throws slow, controlled attacks that require you to use a specific kata sequence as a response. For example, if your kata includes a block followed by a counterstrike, have your partner attack with a slow punch while you execute the block-and-counter. Gradually increase the speed and randomness of the attacks. The goal is not to win the exchange but to maintain your corrected form under pressure. If you revert to old habits, note which attacks triggered the regression and return to decomposition for those specific entries. Pressure testing also reveals whether your techniques are genuinely effective or if they need further refinement. Many practitioners discover that their beautifully executed kata techniques are too linear or too slow for live opponents; this feedback is invaluable for adapting the kata to real conditions.

This workflow is designed to be self-administered, but working with a certified Cedarzz coach can accelerate progress by catching subtle errors you may miss on video. The key is consistency—practicing the correct pattern for 15 minutes daily is far more effective than two-hour sessions once a week.

Tools, Training Aids, and the Economics of Improvement

Restoring practical power to your kata does not require expensive equipment, but the right tools can accelerate progress and provide objective feedback. This section reviews the most effective training aids, their costs, and how to integrate them into your workflow. We also discuss the time investment required and how to avoid common economic pitfalls like over-investing in gear before fixing your technique.

Essential Low-Tech Tools

The most powerful tool is a simple smartphone camera. Recording yourself from multiple angles and reviewing in slow motion is free and reveals flaws that are invisible during live practice. A mirror can also help, but only if you are already aware of what to look for—otherwise, you may reinforce bad habits. A heavy bag (starting around $80-$150) provides immediate tactile feedback: a weak strike will bounce off or hurt your hand, while a properly aligned strike will penetrate the bag with minimal discomfort. Focus mitts with a partner are even better because they allow for dynamic movement. Resistance bands ($10-$20) are excellent for hip and shoulder drills because they provide variable resistance throughout the range of motion. A metronome app (free or $5) ensures consistent timing during integration drills. Finally, consider a foam roller or lacrosse ball ($10-$20) for myofascial release; tight hips and shoulders are often the hidden cause of poor technique.

Intermediate Technology Options

For those who want quantitative feedback, several affordable technologies exist. A simple force sensor pad (around $100-$200) can measure ground reaction force and show you whether your weight transfer is complete. Some modern smart punching bags (like the Pop-a-Shot or similar, $300-$500) track strike force and speed, giving you objective numbers to compare over time. However, these tools are not necessary—most improvements can be assessed qualitatively by feeling the impact and watching video. The danger of relying too heavily on numbers is that you may optimize for a single metric (e.g., peak force) while neglecting other factors like recovery time or movement efficiency. Use technology as a supplement, not a replacement for mindful practice.

Time Investment and Realistic Expectations

Based on observations from multiple training groups, most practitioners see noticeable improvements in power within 4 to 6 weeks of consistent daily practice (15-30 minutes per day). The first two weeks are often frustrating because the corrected movements feel unfamiliar and slower. This is a sign that your nervous system is rewiring—do not revert to old habits for comfort. After about 3 weeks, the new patterns start to feel natural, and by week 6, many students report that their old kata feels weak in comparison. The total time investment to fully restore power to a single kata is roughly 40-60 hours of focused practice. This may seem steep, but it is less than the hundreds of hours you have already spent on uncorrected practice. The economic cost of training aids is minimal compared to the value of time saved by avoiding plateau. Cedarzz also offers online coaching packages that range from $50 to $200 per month, depending on the level of personalized feedback. For many, this investment pays for itself in reduced frustration and faster progress.

Common Mistakes in Tool Selection

Avoid the temptation to buy advanced gear before you have mastered the basics. A $500 smart bag will not fix a mistimed hip rotation. Begin with the free or low-cost tools—camera, band, metronome—and only upgrade when you have a specific need that your current tools cannot address. Another mistake is training with too much resistance too soon: heavy resistance bands can mask timing errors because you rely on brute strength to move. Start with light bands and focus on speed and coordination first. Similarly, avoid heavy bags that are too hard; a softer bag allows you to feel the penetration of a correct strike without injuring your hands. Remember that tools are amplifiers: they make good technique better and bad technique worse, so prioritize technique first.

Growth Mechanics: Building Momentum Through Consistent Practice and Community

Restoring practical power is not a one-time fix—it is a continuous process of refinement that builds momentum over time. This section explores the psychological and social factors that sustain long-term improvement, including how to structure your practice for steady progress, how to use community feedback effectively, and how to avoid plateaus. Growth is not linear; it involves cycles of rapid gains followed by periods of stagnation. Understanding these cycles helps you stay motivated when progress seems to slow.

The Spaced Repetition Approach

Instead of cramming all your corrections into a single intense session, spread them out over multiple days using spaced repetition. Research in motor learning suggests that practicing a skill for 15 minutes daily over 30 days is more effective than practicing for 2 hours once a week. Cedarzz recommends a daily schedule: Day 1: diagnostic review (watch video, note flaws), Day 2: decomposition drill for flaw #1, Day 3: integration of flaw #1 into three movements, Day 4: full kata slow, Day 5: pressure test with partner, Day 6: rest or light flow, Day 7: review and adjust. This cycle ensures that each correction is reinforced before it fades. Use a simple journal or app to track which flaws you are working on and how the technique feels each day. Over time, you will see patterns: some flaws resolve quickly (within a week), while others require sustained attention (several weeks). The key is to not abandon a correction prematurely—give it at least two weeks of daily focus before deciding it is fully integrated.

Leveraging Community Feedback

Training alone can lead to blind spots. Find at least one training partner who is also working on practical power and exchange feedback regularly. Record each other's kata and review together, pointing out specific moments where the technique deviates from the frameworks. Cedarzz online communities (like the official forum or local meetups) provide a structured environment for this kind of peer review. Avoid falling into the trap of only training with people who praise you. Constructive criticism is more valuable than empty encouragement. If you cannot find a local partner, consider hiring a Cedarzz coach for a monthly video review—they can spot issues that even experienced practitioners miss. The social accountability of having a coach or group also helps maintain consistency during the inevitable motivational dips.

Plateaus and How to Break Through

Every practitioner hits a plateau where progress seems to stop. This is usually because your body has adapted to the current stimulus, and you need to increase the challenge. Common ways to break a plateau include: (1) increasing the speed or resistance of your drills, (2) changing the order of movements in the kata (do them in reverse or in a random sequence to challenge your nervous system), (3) training with a heavier opponent who forces you to generate more force, or (4) reducing the time you have to complete the technique (e.g., performing the kata within a shortened time frame). Another effective method is to take a short break (3-5 days) from the specific kata you are working on and focus on cross-training, such as strength training for the hips and core, or practicing a different kata. When you return, the patterns often feel refreshed and more automatic. Plateaus are not failures—they are signs that your body is finishing one phase of adaptation and needs new input to grow.

Remember that growth is not just about physical changes. Your confidence in your techniques will also increase, which in turn makes you more willing to engage in pressure testing. This creates a positive feedback loop: more confidence leads to more effective practice, which leads to more power, which leads to more confidence. Trust the process and stay patient.

Risks, Pitfalls, and Common Mistakes: What to Avoid on Your Journey

The path to restoring practical power is littered with common mistakes that can derail your progress or even cause injury. This section identifies the most frequent pitfalls we have observed in practitioners of all levels, along with practical mitigations. By being aware of these traps in advance, you can avoid wasting time and frustration.

Mistake #1: Overcorrecting One Element at the Expense of Others

It is common for practitioners to become obsessed with one aspect—say, hip rotation—and neglect everything else. They drill hip thrusts for hours, but their breathing becomes shallow, their shoulders tense up, and their footwork suffers. This leads to a new set of problems that are just as severe as the original. To avoid this, use a balanced checklist that includes all four elements: force generation, structure, breathing, and timing. After each practice session, rate yourself on a scale of 1 to 5 for each element. If one score drops significantly, you are likely overcorrecting another. A Cedarzz coach can help you maintain this balance by providing an external perspective. Remember that the goal is a harmonious system, not a single impressive feature.

Mistake #2: Ignoring the Transitions

Many kata practitioners focus on the individual techniques but neglect the transitions between them. In practical combat, transitions are when you are most vulnerable—your weight is shifting, your structure is temporarily compromised, and your breathing may be disrupted. If your kata has a pause or a wobble between movements, that is a weakness that an opponent can exploit. To fix this, practice the kata as a continuous flow, not as a series of poses. Use a metronome to ensure that the time between movements is exactly the same as the time within movements. Cedarzz recommends a drill called "transition focus": perform only the transitions (the half-second between two techniques) at normal speed, stopping at the end of each technique to check alignment. Gradually reduce the stop time until the transition is seamless. This drill often reveals that the transition itself is the source of the power leak.

Mistake #3: Training Only in Ideal Conditions

If you always practice on a smooth dojo floor in bare feet, your body will not be prepared for the unpredictable surfaces of real life. Grass, gravel, wet pavement, or uneven ground will alter your balance and force generation. Similarly, training only in a gi with no obstructions does not prepare you for wearing a jacket or carrying a bag. Cedarzz suggests occasionally practicing your kata in different environments: on a grassy lawn, on a hard concrete surface, or while wearing a backpack. This forces your body to adapt its structure and timing to the conditions. Also, train with a partner who wears protective gear and throws unpredictable attacks. The more varied your training context, the more robust your practical power becomes. Avoid the trap of "perfect practice" that only works in a controlled environment—true power is context-independent.

Mistake #4: Pushing Through Pain

It is common to experience muscle soreness when you start emphasizing different muscles (e.g., your hips may ache from the new range of motion). However, sharp joint pain—especially in the knees, hips, or shoulders—is a warning sign that your alignment is wrong. For example, if your front knee hurts during a forward stance, you may be twisting the knee instead of rotating the hip. Do not ignore this pain; it will lead to chronic injuries that set you back months. Instead, stop the movement and analyze your alignment using video. If you cannot identify the issue, consult a coach or a physical therapist. Cedarzz includes a pre-workout mobility and activation routine that helps prepare the joints for the new movement patterns. Always warm up thoroughly, especially the hips and shoulders, before attempting high-speed or high-resistance drills. An injury is the single biggest setback in your progress, so prioritize longevity over short-term gains.

By being mindful of these common mistakes, you can navigate the restoration process more smoothly and avoid unnecessary detours. The next section addresses frequently asked questions that arise during this journey.

Frequently Asked Questions: Addressing Common Concerns and Clarifying Myths

Over years of coaching and peer discussions, certain questions arise repeatedly from practitioners at all stages. This FAQ section aims to clarify misunderstandings and provide definitive guidance on common dilemmas. Each answer is grounded in the biomechanical and pedagogical principles discussed earlier, with practical advice you can apply immediately.

Q1: Will correcting my kata make it look less beautiful?

No, but the definition of beauty may shift. Traditional kata aesthetics often emphasize symmetry, sharp stops, and controlled angles. Practical power techniques may appear more fluid and less "snappy" because the arms remain relaxed until impact. However, many judges and examiners are beginning to appreciate functional movement over rigid form. If you compete in traditional tournaments, you may need to maintain some external polish for scoring purposes. In that case, practice two versions: one for competition (more aesthetic) and one for combat (more functional). Over time, the two can converge as judges adapt. The beauty of a powerful technique lies in its efficiency, not in its stiffness.

Q2: How do I know if I am actually generating more power?

Objective feedback is best. Use a heavy bag and compare the sound and feel of your strikes before and after corrections. A more powerful strike produces a deeper thud, not a slap. You can also ask a partner to hold focus mitts and rate the impact on a scale of 1 to 10. The force sensor pads mentioned earlier provide quantitative data, but subjective feedback from an experienced coach is often sufficient. Another indicator is your own body: a well-executed technique should feel effortless, with the power coming from the ground rather than from your arm muscles. If you feel strain in your shoulder or arm, you are still muscling the technique.

Q3: Can I apply these corrections to any style of karate?

Yes, the biomechanical principles are universal. Whether you practice Shotokan, Goju-ryu, Wado-ryu, or Shito-ryu, the same laws of physics apply. However, the specific stances and movements vary, so you must adapt the correction to your style's unique demands. For example, a Goju-ryu practitioner may emphasize shorter stances with more hip rotation, while a Shotokan practitioner uses longer, deeper stances. The diagnostic and decomposition frameworks remain the same—you just adjust the target alignment. Cedarzz has worked with practitioners from all major styles and found that the underlying weaknesses are surprisingly similar: mistimed hips, poor breathing, and tense shoulders are universal issues.

Q4: How long before I can see results in sparring?

Most practitioners report noticeable improvements within 4-6 weeks of consistent practice, but full integration into sparring can take 3-6 months. This is because sparring requires you to apply techniques under high cognitive load and unpredictability. The new motor patterns must become so automatic that you do not have to think about them. To accelerate this, include sparring-specific drills from the beginning, such as having a partner throw slow attacks that require you to execute a corrected technique. Over time, increase speed and randomness. Be patient—the neural rewiring takes time, but the results are lasting.

Q5: What if I have a physical limitation (old injury, tight hips, etc.)?

Modify the drills to accommodate your body. For example, if you have limited hip mobility, reduce the range of motion in your stances and focus on generating force within that range. Cedarzz emphasizes that power is not about extreme ranges—it is about efficient use of your available range. Consult a physical therapist or a knowledgeable coach to design a personalized program. The key is to avoid forcing movements that cause pain. Many practitioners find that the corrective drills actually improve their mobility over time because they engage muscles in a balanced way. Start slowly and prioritize quality over quantity.

This FAQ covers the most common concerns, but if you have a specific question not addressed here, consider joining a Cedarzz discussion group or booking a consultation. The next section synthesizes everything into a clear action plan.

Next Steps: Your Action Plan for Restoring Practical Power Starting Today

You now have the knowledge, frameworks, and tools to transform your kata from a hollow performance into a source of genuine combat power. The remaining step is to commit to a structured action plan. This section provides a concise, step-by-step roadmap that you can implement starting today. No more analysis paralysis—it is time to apply what you have learned.

Week 1-2: Diagnostic and Decomposition

Begin by recording your kata and identifying your top three weaknesses using the checklist from Section 3. Focus on the most impactful flaw first. For example, if your hip rotation is mistimed, spend the first two weeks exclusively on decomposition drills for the hip thrust. Practice 100 reps daily, using a resistance band for feedback. Also, start a daily breathing practice: 5 minutes of diaphragmatic breathing while sitting. Do not attempt to integrate other corrections yet. This phase may feel slow, but it lays the foundation for everything that follows. Set a reminder to re-record your kata at the end of week 2 to see if the single correction is visibly improved.

Week 3-4: Integration and Progressive Overload

Once the first flaw is improved, begin integrating it into short segments of the kata (3-5 movements). Use a metronome set to 60 bpm to maintain consistent timing. Gradually increase speed by 5 bpm each week, but only if the technique remains clean. Add a second correction if you feel ready—for example, work on breathing during the same segments. Use a heavy bag or focus mitts to test impact. If the impact feels weak, slow down and recheck your alignment. Record yourself at the end of each session and compare with the previous week's video. This visual feedback is highly motivating and reveals progress that may not be felt in the moment.

Week 5-6: Pressure Testing and Refinement

By week 5, you should have a solid foundation in the corrected movement patterns. Now it is time to test them under pressure. Partner up with a training buddy and do slow sparring where you consciously apply the corrected techniques. Start with one technique at a time, such as a block-and-counter from your kata. Gradually link multiple techniques. Note which situations cause you to revert to old habits—these are your remaining weak points. Return to decomposition drills specifically for those triggers. This phase is iterative: test, identify flaws, drill, test again. By the end of week 6, you should feel a clear difference in your power and confidence, even in sparring conditions.

Long-Term Maintenance and Growth

Once you have restored power to one kata, apply the same workflow to your other kata. Each kata will reveal new weaknesses because the movements are different, but the process remains the same. To maintain your gains, incorporate a "maintenance session" once a week where you run through all your corrected kata at full speed with a partner or heavy bag. This prevents regression. Additionally, continue to seek feedback from coaches or peers—new eyes can spot nuanced issues that you have become blind to. As you progress, you may want to explore advanced topics like adapting kata techniques for ground fighting or multiple attackers, but the core principles of force generation, structure, and timing remain your foundation.

The journey from a kata that looks good to one that actually works is challenging but immensely rewarding. You will not only become a more effective martial artist but also deepen your understanding of the art. The Cedarzz methodology is designed to empower you with self-correction skills that last a lifetime. Start today—record your first diagnostic video and identify your primary weakness. Your future self will thank you.
