I have question about my biceps. I am a Lefty. how come my left bicep kind of falls inward like a slump when I don't flex it and feels kinds of flabby and until I make a fist. But on my right side which is non dominant the muscle seems stiff. It is really weird as I always heard your dominant hand side should be stronger. I also do 40 reps on the left and 30 on the right trying to fix it but I have seen no change. Both sides use 11lbs dumb dell and 3 to 4 sets.
Any ideas? or Fixes?
Thanks
