To what extent should I go to the gym to exercise? Recently, I often go to the gym to exercise my arm muscles and abdominal muscles, but I always feel a little overdone.
The main parts of arm muscles are biceps brachii, triceps brachii and brachialis. If you are practicing muscle lines, it is lighter many times. The block surface is for practicing arms and needs weight stimulation. Each movement 12, 4-5 groups, biceps brachii can train 3 movements. The same is true of the three heads of the arm.
