"I have always wondered about the emphasis of Krav Maga training. Like what is the percentage breakup of tecnique and training during a normal class."
Over here in Germany where I practice, the typical breakdown runs like this (90 mins training session):
- warmup (calisthenics, fighting games, slow-fighting etc.): about 15 mins
- drills / technique / scenario practice: about 1 hour
- aggro-drills / hard scenario practice: about 15 mins
- for those students who want and can, full-contact sparring is done after training as add-on
Of course, this can and will vary wildly in special circumstances - e.g., training outside the gym, incorporating weapons training, "environmental scenario" training (think training to fight/escape in a parking lot / bar / car / park etc.).
I have also trained in Poland (Thomasz Adamczyk) and with some of the Israeli instructors (Eyal Yanilov, Avi Moyal) in (civilian) seminars and courses, and the breakdown is very similar, with no more than 30 mins at the beginning / end for warm-up / power-out (aggro stuff) respectively.
What I observed (and like) about Krav Maga: the higher the level of the instructors, the more analytical the training. There is really much more than the physical movements in training Krav Maga, and the top instructors will install that mindset very quickly in you. "Look around - check the environment - what is the problem - what are possible solutions" are constant phrases at the seminar, and possible solutions will always be analyzed and cross-checked in practice. E.g., "You think you can go out that window? Try it!" - only to discover that you were about to jump down some meters into garbage cans.
Fitness and working out is highly important for self-defense, but it is not the primary focus of the typical Krav Maga class over here to install them in you. Fitness is, more or less, the responsibility of the individual pupil. The primary focus is on installing a problem-solution mindset in the pupil and reinforcing good solutions by realistic practice.
Full-contact sparring is also not regarded as this important over here, but for another reason: most civilians (including me) are just not prepared to take the injury risk with realistic full contact scenarios.
Of course, traditional full-contact sparring is good. But most real Krav Maga stuff is too risky to train full-contact (e.g., imagine taking a chair or another improvised weapon like a beer bottle and hitting/thrusting an attacker with it full force - not a good thing - same for sparring with knives - even with the rubber ones this is very risky (damage to eyes etc.)).
A self-defense situation is not very much like traditional sparring. Differentiating factors include: the physical environment, presence of multiple attackers, use of weapons (knives, sticks, guns, improvised weapons, etc.), no "rules" (e.g., eye gouging, scratching, biting, etc. are all excellent ideas), legal limitations etc. ad nauseam. If you are in the army, in a special unit, you may train stuff like this full-force. But you will also pay the price in terms of injuries and/or necessary safety equipment to prevent them. And this is not practical nor necessary for civilian use.
Just my 2 cent from the Europe side of Krav Maga,
