I was thinking the other day about ATG vs parallel squats. The argument for parallel is that not everyone has the flexibility or proper proportions to go ATG without rounding the lumbar spine. Seems like a sound argument. What I wondered, though, is why there is not then "benching to parallel" and so forth. I'd argue that, similar to squatting, body proportions are huge in benching; a guy with long forearms has to retract his shoulders/upper arms to a much greater degree than a stocky, barrel-chested guy in order to get the bar to his chest, putting the shoulders in a potentially dangerous position very similar to what happens to the lower backs of guys ill-suited to squatting ATG. Any thoughts?
