I'm saying that with quiet confidence, after years of being on here. I don't have to prove anything. Anyone who wants to see proof in person can pm me.
pumpster you cant dismiss what i wrote (about hacks, squats, front squats, power suqtas all being equal) by saying you have great legs , better than mine, when you don know what my leg looks like and you have never shown anyone what yoru legs look like.
i already mentioned that yes some exercises do stress different areas of a certain muscle. for example, incline bench, flat bench, decline bench, dumbell flies. all stress a bit different areas of the pec. but any exercise is just as productive as anyother exercise, in terms of stimulating growth... your msucle has no idea whther its doing a sqaut, a hack squat, a front squat...al it knows is it is being told to contract and push a whole lot of weight. (it doesnt know how much weight its pushing either, but thats a different argument entirely)
