How to build very thin muscles?
Practice every day, never rest, high school study pressure, class ends at 9 o'clock every day. The first thing I do when I get home is exercise. At that time, I made a plan for myself. Dumbbell shrugged 200 times, bent over 200 times, sat-ups 200 times and dumbbell squats 200 times. My dumbbell weighs 12kg. After practice, I collapsed on the bed, my ears were buzzing, my eyes were blue and I didn't want to write my homework. I do this every day. I'm going to practice swimming on weekends except weekends.
