Mechanically, does the Jefferson squat offer any advantage over just wide stance squats? It was as if Kai was doing "weird" excercises to make it seem like he was doing something novel? I remember he said he started all back workouts with dips which seemed weird to me but the other day I looked at a nautilus dip machine at the gym and I think it said it worked the lower traps?
Regarding pull ups for back, do you guys really do overhand pull ups instead of pulldowns? For me it's such a heavy exercise I feel like I can't do even a single rep the way I'd like to, the range is real short.
