Before doing sit-ups, in order to avoid muscle strain, you need to do warm-up exercises first, lie flat on the mat, bend your knees with your legs, and make a 45-degree angle between your calves and the ground. Put your hands behind your head, or put your hands on both sides of your ears, and do it at a constant speed. Don't go fast and slow at once.

Precautions:
Although sit-ups are very convenient and can achieve a good weight loss effect, the effect will be better if you practice sit-ups with some aerobic exercise.
Simply relying on sit-ups can only achieve local fitness effect, because sit-ups are aimed at abdominal muscle groups, and the effect of long-term exercise may strengthen abdominal muscle strength, but other parts of the body, such as thighs and buttocks, get less exercise. Only by effectively combining sit-ups with aerobic exercise can we really achieve the perfect weight loss effect.
