The correct way to eliminate the arm:
1. For upper arms and shoulders:
Legs are shoulder width apart, and each hand holds a dumbbell (if there is no condition, a 500ml water bottle can be used instead), with palms facing each other. The position of the shoulder is forward beyond the pelvis, and the knee is slightly bent; Keep the dumbbell close to your body, lift it to your shoulders, extend your elbows outward, and slowly lower it to its original position. Pay attention to balance the force and don't lean to one side, otherwise the arms will be asymmetrical on both sides. (Do 2~3 groups at a time, with 8~ 10 strokes for each group)
2. For arms, shoulders and back:
First of all, sit in a chair with a backrest (standing is ok, but legs are shoulder-width apart, chest out), hold a dictionary or a bottle of water with appropriate weight above your head with both hands, keep your upper arm still, and make your forearm stretch and bend behind your head. When the forearm is extended backward, it is not completely straight, maintaining a certain tension, and when it is flexed, it is not completely relaxed. Forearms and upper arms are at 90 degrees. (Do 2~3 groups at a time, 5~8 times in each group)
