i was thinking about this the other day. lot of old tcm training has ma-bu or horse stance training and other variants. watch how controlled he is as he seem to shift weights effortlessly while remaining butter smooth and balanced at all times. i've done a tiny bit of martial arts and it's really not easy to move like that...
if one can do single leg body weight squats easy would this person be able to squat 2x his body weight pretty easy? i'd think so...
