For bicep dumbbell curls, what's your max?
Red, have you tried Jack3d or 1MR yet?
Also, yes, strong legs = strong everything else. Protip: strong core = even stronger everything. I had a buddy that only worked out specific muscles and hardly did legs that was toned and as soon as he worked out his core that fool got mad ripped.
nah im poor atm i can barely afford this protein lol. legs was my weakness for sure though i never worked them lmao

now that i started doing leg extensions etc i can really notice the gains. how much is jack3d and 1mr i could try it a month or so i guess ifs not like super expensive or anything.
