| Try less iso movements and do more compound lifts. B
If you focus on getting strong you will get bigger, IF your diet is up to par. So try to squat more, deeper, try to deadlift more weight, press more weight, etc.
Do more back exercises...like, double your chest exercises. **** the chest. More legs. If you train your lower body as much as you trained your arms, you'd be going somewhere.
Your legs are huge muscles. If you get them bigger, you will weigh more. Your arms are tiny in comparison. |
