I know a lot of people suffering from one arm being bigger than the other or stronger whatever it may be...but I think I have like a genetic freak disorder or something....its clearly visible my right arm is bigger and more defined and I can put like a 50-55 lb dumbell in my right hand and do it without cheating 10 times well...put it in my left and cheat...use my back and shoulder whatever and get like 3 or 4 reps maybe...what the hell can i do lol I think if I didnt cheat and tried to just use my bicep i would be able to do like 2...its really really sad and im getting frusterated and I feel like I always do a lot less with my right arm fearing it will just get bigger and leave my left one behind even more.
Bean,
My friend, you are not the only one who has this problem. Most of us have this problem in where one arm is dominant to the other. In my case, my left arm is weaker than the right. It used to bother me that my left was so weak and my right was stronger and bigger. In an attempt to bring proportion to the muscles that I had trouble with I started to do barbell exercises instead of dumbbells. First when I started my left lat was extremely behind. I worked on that by doing lat pull downs and I dropped the dumbbell rows that I was used to doing. My left arm was about 1/2 an inch smaller than the right. I started to do more barbell exercises and tried to limit the dumbbells.
My theory is that although one arm may be dominant or one side may be dominant, instead of using other parts of your body such as shoulders and back to aid and cheat the lift, why not use your dominant other half? If the right picks up more and the left not so much hit the barbells. The right arm will support the left allowing it overtime to grow.
Don't take my word for it. This response is just from my personal experience with symmetry in body parts. To this day, my lats are evened out. Before it used to look like I only worked out one side of my lats while the other, I decided to leave alone. To this day my left biceps are 1/4th or 1/5th off from my right. Try this, maybe it will help you out.
