e-peen doesn't come into it, squat "aids" are beyond stupid.I don't see the big deal with a squat aid. Are gloves homo then? How about knee supports? Kinesio tape? Do you really want to try and out E-peen me? ...silly little boys
Delvis, it is to do with the Acromion (?), it makes extending my arm out down the length of the bar difficult sometimes and rotation can be stiff which makes stacking heavy weights on my shoulder difficult sometimes.
If you can't get your shoulder in position then get it seen to, if you don't you'll only injure it more severely or it'll cause problems elsewhere because you're having to compromise your positioning.
And yes, gloves are very gay.
