understand that what edgar did is not about being strong, it is about muscular endurance. It certainly helps, in a sense, to be strong, but without the endurance he would not get very many reps. Lw's, or more specifically, guys with smaller frames, should perform better than there heavier counterparts; there is simply a shorter range of motion meaning less work is actually being performed, even relative to weight class. Also, I am by no means an expert on exercise science, but dont chins looked suspiciously similar to half-reps; maybe i can reach the same number by doing quarter-reps? btw, just for shits n gigs, i'm 6'3'', 225, I can press my bw roughly 10-12 times(full reps) and do probably the same number of chins if super-setted with presses(my pr for chins is something like 16).
