I m 25 years old and I m going to gym for 3 days in a week. When I workout for biceps in heavy weight, my partner realized that my left hand is exerting more strength than my right hand. When I look in front of mirror, I also see the difference in both hands. I can also feel the difference that my left hand is more tight and my right hand is looser.
What can I do to ensure that both hands' size and strength are equal?
