my right arm has a tendency to absorb bicep exercises in the forearm instead. I’ve tried all different types of curls, preacher curl machine where I can rest the handle on my wrist and not grip it with my hand to take the load off my forearm, and still my right bicep just doesn’t pump as hard as the left. They’re both growing, and I’ve asked other people if they notice difference in size and only I notice that the left is slightly thicker. It’s also longer than my right. They have like equal peaks though. I had a similar issue with my lats but a lot of unilateral work is helping get better mind muscle connection and even them out, I just still have trouble with my arms. Anyway it just pisses me off most days I do arms I leave the gym feeling like I cheated one of them. If anyone else has experience with this and could offer insight that’d be great.
