First I'm am the weakest squater ever, I'm not new to BBin well to squates I'm kind of new. I have been lifting since 16 kind of cause all I did was bench. Shit I was benchin 250 before I could finish a set of ten reps on an eazy curl bar with 25s on the end. Now I have picked up squates and am hella weak I can only do like 205 for maybe like 2 full sets of 10. And that's a hell of an inprovment. Now back to topick I can only do like 135 for like 10 reps on front squate cause my shoulders can't take more weight on them, shit that's the weight I put on when I do shoulder press. How do I unprove this?
