There are various local fitness exercises, such as sit-ups, thin waist and abdomen, three rounds of stovepipe in the air, and thin arms while drinking mineral water. Some people persist for a long time only to find that the size of the part targeted by the action has not decreased, but the muscles protrude because of exercise. In fact, this local shaping and fat reduction action can't burn off this part of the fat, it will only make the muscles here stronger.

Therefore, if you want to partially shape and reduce fat through fitness exercise, you must do aerobic exercise for at least 30 minutes before you can shape and reduce fat. Local shaping and fat reduction target area: arm. Action: Stand with your feet apart, shoulder width apart. Stretch your hands forward from your sides, then lift them up and stretch them back as far as possible. Skill: keep the whole movement at a constant speed, pay attention to breathing, and try to challenge your limits when your hands are stretched back. Each complete stretch counts as a complete movement, and all movements are in groups of 20. Only by doing more than three groups at a time according to your own situation can it be effective.
