I have been lifting for quite some time now. But I am 40 and I need more recovery time now. I do the compound lifts such as the deadlift, the squat, the bench press, the standing overhead barbell press, the bentover barbewll rows, and weighted pull ups. My problem is my weak legs. I can barely squat over 200 pounds for a set of 8 reps. It's embarrassing. I try very hard. I'm just not getting much stronger in my legs. Is it worth it to squat, even if it is low weight? Am I getting anything out of this by squatting low weight?
