J´Sジムではリアルファイティング(実戦)は護身術の次のステップです。

• 　​リアルファイティングは生命をかけた戦いであり、ジムの外での戦いは敵の大きさや数、武器を持っているか素手か、いつ、どこで起こるか、その他一切わかりません。

　このような戦いはYouTubeにあるようなものとは大きく違い、若者がささいなトラブルや挑発から数発のパンチを打ち合うようなものではありません。この場合はたいていは何回かなぐったりつき飛ばしておわります。彼らは生命をかけて戦っていないからです。格闘技とも大きく違います。今度説明します。

リアルファイティングとは何か？どのようにトレーニングするべきか？

• リアルファイティングを教えるシステムでは身体的テクニックと精神的戦略を起こり得る生命に関わる状況で使える必要があります。それは何が起こるかわからない状況に備えるためです。目的はポイントをとるためでも単に勝つことでもなく、自身を守り敵を倒すことです。
• リアルファイティングではルールは何もありません。体重別ルールや経験も関係ありません。むずかしく思えてもどんな状況にも対応できなくてはいけません。
• 私たちは戦いがいつ起こるか、また起こるか起こらないかもわかりません。だから無理しないで練習するべきです。プロフェッショナルである警備員や警察官などであれば、実際に戦うリスクがあるのでハードな練習をするべきです。しかし怪我をするリスクも大きくなります。多くの人には無理をしない練習の方が適切です。ハードな練習の利点と不利な点があるからです。

リアルファイティングはよくこのように考えられています（間違い！）:

• トレーニングはハードであればある方が良く、実際にパンチやキック、絞め技を行うと良いと考えられることがあります。しかし安全に攻撃できる身体の一部しか攻撃できないため、自分より大きくて強い敵や複数の敵には役に立ちません。
• さらに、よりハードなトレーニングをするとケガのリスクが大きくなります。人は強くなるためにトレーニングをしているのであってケガをするためではありません！

For us at J's gym realistic or "real" fighting is the next step after self-defense.
Real fighting is how you should fight if your life depended on it, in real life outside the gym, where size and number of opponents, weapons or no weapons, place and time, etc. are all unknown!
This is very different from a lot of the fights you can find on YouTube where young men do the monkey dance, meaning they're exchanging a few punches to settle some minor dispute or provocation. It usually stops after a few exchanges of blows and pushes. They are not fighting for their life! Sports fighting is also very different, more about that later.

What is realistic fighting and how do you train for it?

1. A system that teaches realistic fighting will teach you both physical techniques and mental strategies that can be applied to any thinkable situation where you might have to fight for your life. It's about getting ready for the unknown. The focus is not on scoring points and just winning but about defending yourself and defeating the assailant.
2. Real fighting should not be restricted by any kind of rules, weight classes, experience, etc. When fighting outside there are no rules, weight classes and so on so we need to learn how to deal any situation no matter how difficult it appears to be.
3. Since we don't know when or if ever we need our skills, realistic fighting should be trained in a moderate way. Only professional guards, police, etc. should train harder because of their increased risk of having to apply their skills. But since this also increases the risk of injuries a moderate training level is better for most people when you consider advantages and disadvantages of hard training.

What realistic fighting often is thought to be:

1. The harder the training the better. "Realistic" full contact punches, kicks and chokes, etc. But since only "safe" areas of the body can be attacked, this way of fighting often doesn't work against a physically bigger and stronger opponent or multiple opponents.
2. The harder training also increases the risk of injuries a lot and people train realistic fighting in order to become stronger, not injured!

日本語今度書きます。英語の文章。Part 1
I often get asked questions about self-defense versus sports fighting (格闘技 in Japanese) so I decided to write down how I define self-defense, realistic fighting and sports fighting. I feel many people are confusing the different terms and end up not realizing what they are actually learning. I'm starting with a few thoughts on self-defense, with more to be added hopefully soon.

​Self-defense
What self-defense should be like: Teaching of the simplest and best techniques for dealing with the most common attacks and teaching of the mental preparation needed to handle the stress of such situations.
Self-defense should be taught as a limited course to quickly equip the person with the most basic skills to handle a situation and get away safely. Think of it as learning self-defense first aid: you learn just enough to deal with the most common attacks and get away.

What it often is taught like: Teaching of techniques to defend attacks that are not likely to happen, techniques and tricks that are of very little value out in the real world, and no mental preparation on how to deal with a real situation.

Real self-defense is more than just a technique. It's also about what happens before and after you get into a situation where defending yourself is needed.
Without mental tactics many people will just freeze when they come upon a dangerous situation. So what happens before is important.
Just applying a technique to free yourself might not be enough. What will the attacker do next if you stop there?
Sometimes simply running away isn't that easy. What if you are in an apartment, elevator, public toilet or a similar confined space? The techniques to free yourself are just a little part of self-defense curriculum.
