against the chest. Push up, put in your elbows, put your elbows in your chest. The dumbbell is slightly forward while rising, showing a parabolic trajectory. When the arms are straight, the center of gravity
of the dumbbell is close to the support point of the shoulder joint. But don't just happen to be at the point of support of the shoulder joint,
which will allow the skeleton to support the weight of the dumbbell(this case where the weight is supported by the bone rather than the
muscle is called "locking"), making the pectoral muscles relax and affect the exercise effect. Then, the two straight arms are opened to the sides
, the arms are slowly bent, and the dumbbells fall vertically. When they fall to the lowest point, they push up. Repeat. Breathing Method: Exhale with your nose when pushing up and inhale when reducing.

Most people, especially girls at home use dumbbell and barbell goal, is to let the shoulder, arm and so on parts of the line is much more good-looking.
So doing arm flexion, levelly obeying such small muscle group exercises, group number selection principles should follow the "small weight, many times".
