I try and never make fun of how people train, Esp if they get hurt. But I must mention I hate kipping Pull Ups. Next - Some crossfit is awesome, It works well in some aspects for fighting and other types of work. Some of these guys are smaller and pull more weight with ease then most of us here and some are bigger then us here and still do more weight, with good form.
This link is a guy doing the king kong
1) Deadlift @ 500lbs
2) 2 Muscle Ups
3) 3 Squat Cleans 275lbs
4) Hand stand Push Ups
All For threee rounds So total - 500x 3 singles , 6 muscle ups, 9 Squat Cleans, 9 hand stands. Thats more then most of the guys here lol and he is smaller..However he did do olympic games
This next guy is smaller then most here ( also doing king Kong) and he is pulling 455 for 3 singles 2 Muscle ups for a total 6, 3 Squat cleans for 250 for a total 9 and 4 hand stand push ups. Thats pretty good
