The requirement of 500 sit ups is for contact sparring, not for flexibility--see the title of the the section 19th column with info on strengthening the trunk (“Long-term sequence of strength exercises in preparation for combat sports and martial arts”). For flexibility you need only as much strength and muscular endurance as required by the exercises that prevent gradual-onset injuries, which could be caused by stretches (dynamic, isometric), kicks, and by exercises that at the same time strenghten and stretch your legs (adductor flys, adductor pull-downs). The specifics are given on the video “Secrets of Stretching” ( http://www.stretching.info/secrets.html ). On the DVD these are in the chapter “Prepare for Stretching.”jean da best wrote:500 situps.ok, i see this flexibilty program is somewhat out of my reach
Something that I wrote the 24th column pertains here too.
