Choose this exercise to lose weight by doing sit-ups. There are two points to note.

Men should choose crunches to reduce abdominal fat: (upper abdomen)

During the entire movement, the purpose of your exercise is not to raise your body completely, because this is not a sit-up competition. No matter how high you sit up or how many times you sit up, no one will award you an Olympic gold medal. Your purpose is to exercise your abdominal muscles, not how high or how many times you sit up.

Action description: Lie on your back, bend your legs naturally, cross your hands in front of your chest, place your palms lightly on your shoulders, raise your elbows to an angle of 60-80 degrees with your body, slightly retract your jaw, relax your neck, and then use your chest to "slowly" (remember: slowly) lift upward (remember: upward) until you feel your abdomen contract and squeeze to the top position (in this case, your abdomen will definitely feel this contraction and squeeze to the top), then slowly fall back down. Do about 15 times per set (I believe you can't do it after 15 times) Do 4 to 5 sets, and adjust the rest time according to your physical strength in the middle, and the length should not exceed 3 minutes.

Note:

1: When you don't have a personal trainer to guide you and you don't do these exercises often, try not to hold your head with your hands to complete the movements, because you can't control the strength and your cervical spine will be under great pressure.

2: When lifting up, you must focus on "lifting your chest up and forward". You don't have to worry about your abdomen. As long as you focus on lifting your chest up and forward and your abdomen, you will definitely get a greater workout.
