My weakest muscle by far are my biceps. It seems however heavy or intense I train them, they don't grow like evrything else. I'm going to switch to doing extremely isolation exercise with very strict form to help really hit just the bicep. When you guys lift them, how many reps do you guys try to get. I usually try to get between 6-10, but I think I'm going to switch it up like I said to very strict form and more reps, like at least 10 reps. Any suggestions???
