Muscles are relaxed and elastic when they are relaxed. Only through exercise and intensive training can muscles contract, tighten and expand.

Want to build hard muscles need to follow the following methods:

1, with heavy weight and low frequency. In bodybuilding theory, RM is used to indicate the highest number of repetitions that a certain load can do continuously;

2, the number of groups, specially set aside 90 minutes to focus on a certain part, do 8 groups for each action, fully stimulate the muscles, the longer the muscles need to recover;

3, long displacement, whether rowing, bench pressing, pushing back, bending, we must first put the dumbbell as low as possible, so that the muscles can be fully stretched, and then raise it as much as possible;

4, slow speed, slowly lift, and then slowly put down, so as to stimulate the muscles deeper.
