For a lot of exercises my right arm/leg is stronger than the left. I am doing only dumbbell & bodyweight exercises. Is there a proper way to accomodate this? Right now I can curl probably 50lb w/ right and only 30 with left. So I can undertrain the right and use the same weight on each arm, or is it ok to use heavier dumbbells on each side? Will I just keep the imbalance going if I do that?
