This is just something I'll never understand. Some people say if you weigh more, you'll be able to squat more faster because you'll put on muscle faster (okay, I can buy that due to hormonal changes and stuff) and because you'll have better leverages.
WTF? How?
It just doesn't make sense. If my upper body is heavier (from fat, or even from muscle), and I'm pushing with my legs, I'm pushing more weight. Otherwise, doing bodyweight squats with no barbell would be easy as hell for fat people.
If my arms weigh more (from fat), benching will not be easier because it's more weight pushing down. I'm working against gravity here. The only way it'll be easier is from a half inch less ROM from getting a bigger/fatter chest.
If my arms weigh more (from fat), rowing will not be easier because I'm pulling my arms up against gravity.
This "better leverage" crap for squatting coming from weight gain has to stop. The only way it would help is if you're working with gravity, like in a tricep pushdown. Otherwise, go ahead and put on a 30lb weight vest and see if you can reach a new PR in your squat because that new weight is giving you better leverage. Or you know what, wrap a weight belt around your thighs and see if that even helps. It won't, it makes it harder.
