Although sit-ups are very painful, it is worthwhile to develop perfect abdominal muscles. Do it once 100-200, 20-30 is 1 group, and at least 5 groups should be done, depending on personal situation. You can increase the weight appropriately, and it is better to put a dumbbell or discus in your hand behind your head.
Push-ups, however, need to remember that you must not get tired once during exercise, and you must do them in groups to be effective. Generally, you should do it at a time 100 or so, and divide it into at least 5 groups, depending on your own situation.
Leg lifting exercises. Action essentials: lie flat, straighten your legs, lift your upper body up 90 degrees, put it down and lift it repeatedly. This is a further abdominal strength exercise. Because leg lifting exercise has a lot of intense abdominal exercise, it is a good exercise to burn abdominal fat.
If you have a lot of abdominal fat, you should stick to aerobic exercise. Running is very effective, which can reduce excess fat and show muscles better. Abdominal muscle training is different from other muscles and needs constant stimulation, so you have to be exhausted every time to achieve the effect. The interval between them should be about one minute. You should be divided into six groups. Second, you should pay attention to strengthening high protein and high fat in your diet. Half an hour after each exercise to 1 hour is the peak of protein intake. Pay attention to eating high-protein food.
I believe that if you persist, you will soon be able to develop perfect abdominal muscles.
