Skillful use of towels is a master! Arm stretching exercises ◆ It is easy to catch a cold, edema and accumulate fat. From the armpit to the back, lymphatic circulation is easily blocked. Affected by fat, it is easy to catch cold, subcutaneous adipose tissue gathers, and the arms and thighs cannot be taken lightly. Next, I will introduce the stretching gymnastics to eliminate the butterfly arm! Expanding the active area of the arm to the maximum extension will definitely make the range of motion of the joint larger. It looks super simple, but when you do it, you may be surprised at the stiffness of your shoulders. Many people will realize that their femoral joints are stiff and do some stretching exercises to improve this situation, but shoulders and arms are easily overlooked. The formation of "butterfly arm" limits joint activity and causes shoulder and arm fatigue. This action not only has stretching effect, but also stimulates pectoralis major muscle in the chest and rhomboid muscle in the back, which can enhance metabolism and lose weight.
