Iam late in my recrutement of my arms, when i do some barbell curl i don’t feel them so much, even with dumbell, i would like to know, if i do a lot of reps with light weight that can help me for “activate” my biceps, for “wake up” them, i dont know, my execution is good, i don’t cheat but i just feel them a little bit, so 100 reps can help maybe in the begining ? thank
