Although Krav Maga shares many techniques with other martial arts, like Savate and Kickboxing (for the fist- and kick-fighting techniques) or Ju-Jitsu (for the grappling and disarming techniques), the training is quite different. It stresses fighting under worst-case circumstances (for example, against several opponents, when protecting someone else, with one arm unusable, when dizzy, or against armed opponents).
Training in Krav Maga is an aerobic workout, and relies heavily on pads. Students take turns holding pads and doing combatives against the pads. This is important because it allows the student to practice the technique at full strength, and the student holding the pad learns a little of what it feels like to get hit. It can be almost as taxing to hold a pad as to practice against one.
Training may employ a speaker system blasting loud music, stroboscope and/or fog machine meant to train the student to ignore peripheral distractions and focus on causing as much damage as possible. Training might also contain ways to deal with situations which could end in fights. Physical and verbal methods to avoid violence whenever possible are taught.
A typical Krav Maga session in a civilian school is about an hour long and mixes aerobic training with self-defense teaching. As levels increase, the instructors focus a little less on aerobic training and slightly more on combatives. First, the instructor will run a very intense drill to get the class's heart rates up. Then, after stretching, the instructor will teach two or three self-defense techniques. In the beginning the techniques will either be combatives (punches, hammer-fists, elbows, knees and roundhouse kicks, for example) or grappling (breaking out of chokes or wrist-grabs, getting out from under an opponent while on one's back). After that, the class usually moves to a drill that combines the techniques just taught with an aerobic technique. Finally, there is the final drill intended to burn out the students. Depending on the class - and on the instructor's mood - this drill may be at the very beginning or at the end of the class.
