Like Michael said, it depends on the school and instructor. The good ones will put you through a rigorous workout with striking and combatives before stepping into the defense training section of the class. Try one of these links to see if the school is associated with KM Alliance, or KM Worldwide, both of which can be directly traced back to the creator of KM, Imi Sde-Or (Lichtenfeld).

well, i was an overweight person before and was extremely nervous about any physical education class
i am quite in good shape now... i did 4 round of insanity, 1 round of p90x, Jillian Michael body revolution, p90x3, les mills pump, Focus t 25, and now i just started combat...
Even though i am quite fit now, i still cant do pull up, i use resistance bands, and i am afraid of doing a front roll over and back roll over....
How is a krav beginer class and what should i expect????? i just started combat just to know how to punch, kick and jab etc....
Is it more intense than the beachbody workout???
thanks
