Dumbbell action:

Target position: You can sit up straight with your shoulders and upper chest, with your legs apart and your torso straight. Hold a dumbbell in each hand, palm forward, elbow bent 90 degrees.

Lift the dumbbell to the top of your head. Control the dumbbell to slowly return to the initial position. Practical effect: A man's shoulders should be wide enough to take responsibility and show momentum. The width of the shoulders depends on the size of the bones and deltoid muscles. Bone is difficult to change because of heredity, but we can exercise deltoid muscle.

Dumbbell exercises:

1, choose the right weight and practice dumbbells.

2, the purpose of exercise is to gain muscle, it is best to choose dumbbells with 65%-85% load. For example, if the weight you can lift each time is 10 kg, then you should choose dumbbells with a weight of 6.5 kg-8.5 kg for exercise. Exercise 5-8 groups every day, 6- 12 times in each group, and the exercise speed should not be too fast, and the interval between each group is 2-3 minutes. The load is too large or too small, and the intermittent time is too long or too short, the effect will be bad.

The purpose of exercise is to reduce fat. It is suggested that each group should practice more than 15-25 times, and the interval between each group should be controlled at 1-2 minutes. If you think this kind of exercise is boring, you can practice with your favorite music, or do dumbbell aerobics with music.
