Action one
Feet are shoulder width apart, hold the water bottle with both hands and lift it horizontally in two directions, palms up, and then turn around (you can turn around 30 times before turning around 30 times).
Action 2
Then put your palm forward in front of you. The upper arm is fixed and the lower arm is raised. At this time, the attention is focused on the biceps brachii on the front side of the upper arm, and the muscles contract. Hands can be raised together or alternately.
Action 3
Stand with your feet apart, holding a water bottle in your hand and holding it high above your head. Then, your forearm droops backwards, your upper arm stays close to your ear, and slowly stretches your elbow until your arm is completely straight. Pay attention to the tightening of triceps brachii, move slowly and don't shake your body.
Action four
Hold the water bottle with both hands, straighten it forward and put it on your chest. Bend the elbow of one arm so that the water bottle falls to the inside of the elbow of the other arm. Alternate hands.
note:
1. When you do it, you will feel that your armpits and upper arms are tight, which is the result of effective actions. Don't give up, you must keep doing it.
You can do this exercise anytime, anywhere, as long as it is implemented for one month. Not only has the underarm lost weight, but the fat on the upper side of the arm has also been greatly improved, which is quite good.
