Starting your journey in martial arts is one of the best decisions you’ll ever make. Whether you’ve joined the British Kempo Society to learn Ju Jitsu, improve your fitness through kickboxing, or simply feel safer walking home at night, the benefits are life-changing.
But here’s the truth: most students (and even some experienced practitioners) fall into common traps that slow down their progress or, worse, give them a false sense of security. At our clubs, we want you to be the best version of yourself, which means training smart as well as training hard.
Here are the seven most common mistakes people make with martial arts and self-defense, and exactly how you can fix them to level up your skills.
1. Chasing "Flashy" Moves Before Mastering the Basics
We’ve all seen the movies: the spinning 540 kicks and the complex cinematic takedowns. It’s tempting to want to skip ahead to the "cool" stuff. However, in Kempo and Ju Jitsu, your power and safety come from your foundation.
The Mistake: Rushing through your stances, footwork, and basic blocks to get to the advanced combinations.
The Fix: Fall in love with the fundamentals. A simple, well-timed jab or a solid stance will save you more often than a fancy kick. Spend time perfecting your guard and balance. If your foundation is weak, everything built on top of it will eventually crumble under pressure.
2. Thinking Gym Sparring is the Same as a Real Fight
Sparring is a vital part of training, especially in our kickboxing and Ju Jitsu classes. It builds timing and reflexes. But a controlled environment with a referee, mats, and rules is very different from a real-world confrontation.
The Mistake: Assuming that because you can "win" a sparring round, you’re fully prepared for a self-defense situation.
The Fix: Train for reality. At the British Kempo Society, we emphasize situational awareness and scenario-based drills. Remember that in a real-life situation, there are no mats, no gloves, and potentially multiple attackers. Use your training to build the tools, but keep your mindset grounded in reality.
3. Using Muscle Instead of Mechanics
It’s natural to want to use your strength to "force" a technique to work, especially when you’re grappling in Ju Jitsu. But if you rely solely on muscle, you’ll burn out quickly and struggle against a larger, stronger opponent.
The Mistake: "Muscling" your way through a technique rather than using leverage, angles, and timing.
The Fix: Focus on relaxation and technique. If a move feels like a massive struggle, you’re likely doing it wrong. Proper Kempo and Ju Jitsu techniques are designed to allow a smaller person to overcome a larger one. Listen to your Instructors when they talk about weight distribution and leverage.
4. Holding Your Breath Under Pressure
Have you ever noticed your face turning red during a heavy bag session or a sparring round? You’re probably holding your breath. This is a natural "fight or flight" response, but it’s a recipe for exhaustion.
The Mistake: Holding your breath when you get nervous or tired, which starves your muscles of oxygen and leads to "gassing out."
The Fix: Practice rhythmic breathing. Breathe out on the "impact" of your strikes and maintain a steady rhythm during movement. Learning to breathe under pressure is a superpower that will keep your mind clear and your body moving.
5. Neglecting Your "Engine" (Conditioning)
Technique is king, but your physical conditioning is the engine that drives it. If you’re too tired to hold your hands up, your technique won't matter.
The Mistake: Thinking that 20 minutes of technique work is enough to handle the physical demands of a high-intensity self-defense situation.
The Fix: Supplement your martial arts with kickboxing or functional fitness. High-intensity training builds the stamina you need to stay in the fight. Check out our About page to see how we integrate fitness into our curriculum to ensure our members are truly "battle-ready."
6. Letting Your Ego Drive Your Training
This is perhaps the most dangerous mistake. It happens when you’re afraid to look like a beginner, or when you refuse to "tap out" because you want to win a practice round.
The Mistake: Letting your ego prevent you from asking questions or admitting you don't know something.
The Fix: Adopt a "White Belt" mindset, regardless of your actual rank. Be coachable, stay humble, and remember that every mistake is a lesson. You can also follow more of my personal journey and insights on training over at www.thedancingfighter.com.
7. Forgetting that Self-Defense Starts Before the First Punch
The best way to win a fight is to not be in one. Many people focus so much on the physical moves that they forget the most important part of self-defense: prevention.
The Mistake: Thinking self-defense is only about what you do once someone grabs you.
The Fix: Focus on "Verbal Judo" and situational awareness. This means keeping your head up (and off your phone), recognizing red flags, and knowing how to de-escalate a situation with your words. True self-defense is about making smart choices that keep you safe before things ever get physical.
