hahha kyomu, that guy has the worst pull-up form I have ever witnessed. Wouldn't get credit for one single pull-up by USMC standards. He is just kicking his legs and using momentum.
for a 250+ pound man, 55 reps is INCREDIBLE it doesnt even matter how much you swing your feet, Its amazing.
but yes, they aint real reps, but he could probably do 40 real ones 35-40
