My right bicep is larger then my left bicep. I've been working out my left bicep more aggressively and continue with the same weight on my right.For some odd reason my right continues to grow with my left but my right remains the same. Should I lift less weight more reps until muscle failure in my left bicep, and continue the beginning portion of my bicep workout the same for both biceps?
It is a common problem. One that I have also. My left bicep and muscles in general are bulkier than those in the right. It is due to your stronger side having more densely packed muscle fibres and hence smaller size than your weaker side.
I actively do reps and sets by using my weak side to determine the max level. That way my weak side is always worked hard while my strong side is not. Over time I hope this will address the size/strength imbalance. Dumbells are the best for doing this
Using dumbbells will help by doing equal weight and set/reps on both sides. Hammer strength machines help in this area also.
