Arm bigger then the other.
hey Marc my one arm is bigger then the other, when I flex my one arm is larger then the other how could I solve this problem or could this be a growing problem?

Could be that you're stronger in one arm than the other, allowing you to train it harder, resulting in it becoming bigger. You could try doing unilateral exercises and focus on growing your smaller arm.
DO NOT FOCUS on one arm. Train them both equally to avoid imbalances. Over time, this should even out!
