Each test varies for BB in Kenpo... I had to do way over 100 pushups, but I have heard of guys in my system that had at least 1000. There is also a good amount of running involved(10-12 miles). So physically it should be test. The big part of it all is to see one at complete exaustion and then see what they can do with nothing left...breaking the spirit A writen test is required in my system. But it is a week before the test. The test usually runs 6-8 hours. Not counting running... The Kumite varies as well. It is usually full contact sparring against 3-5 BB that are chosen.
