i completely disagree that strength equates to size.
when i would train for strength in bench, yes i got stronger, but not much bigger.....
only when i trained w less weight and for higher reps is when i got bigger.
i think more reps get you bigger.....not more weight.
so, this explains the phenomenon......not always the guys with the biggest chest are the strongest.
my advice is to train w BOTH high reps and low reps.....strength and size.
