Hahaha, if you practice the second and third arms, lift dumbbells, pull arm strength devices, and do pull-ups and push-ups, it will be OK. There is no limit to this. If you feel tired, have a rest. . . If you practice abdominal muscles, do sit-ups, 100 a day. If you are practicing ligaments, you should insist on standing and bending down a little every day. If someone helps you, you can do various stretching exercises. . Well, it's more general. In fact, practice wherever you can't, and persistence will have an effect! ! !
