Ok my right arm is way bigger than my left arm. With every workout I do I can only feel it in my right arm even if I use perfect form. For example, today I was benching and making sure i kept the bar perfectly straight. After 1 set, my right arm was swole, sore, hard and vascular. Especially in my bicep which benching doesn't work. My left arm felt nothing at all. No pump, no soreness, nothing. I couldn't possibly have better form even if I tried. I feel like its only a matter of time before my right arm is awkwardly bigger than my left. I wanna fix this but Ive been trying for years now and clearly I can't. Any advice on what I should do?
