Second: when the body is practicing, don't push too hard, try to have rhythm, and don't hurt its biceps. Using dumbbells, sit on a bench and test the inner thigh for 20-25 times. Take a rest for about 40 seconds after you finish, then move on to the next group and do three groups. After that, exercise a large group of muscles. Squats and strong pulling are good, which accelerates muscle growth. Shoulder muscles naturally hold dumbbells vertically and raise their hands upward.
Please adopt it. Thank you.
