Do as many push-ups as possible in each group, and do four groups at a time.

Doing sit-ups can have an exercise effect, but the effect is not obvious. I recommend two methods.

1 First of all, lie flat, preferably on a bench, not a bed. Put your hands on your ears, push your abdomen, lift your head and shoulders, and push up, but don't leave the stool with your back. Feel the contraction and exertion of abdominal muscles slowly as your head moves forward, then lie down, exhale when you contract upward, and inhale when you lie down. At first, you must be slow. To find that feeling, the feeling during exercise is very important. You'd rather slow down and move in a standard way.

Lie flat on the bench, buckle the stool under your head with your hands, straighten your legs, lift it up about 80 degrees, and then put it down slowly, because the muscles will retreat and contract during the process of putting it down, and the exercise effect is the best.

The first action exercises the upper part of abdominal muscles, and the second action exercises the lower part of abdominal muscles. Eight to twelve in each group, four groups at a time, three to five times a week, because excessive muscle recovery should be considered. Drink some milk and eat one or two eggs every night. You can make a few less at first, and then add a little more. As long as there is not much meat on your stomach, you can laugh after two or three months.
