1: You are thin, and there is no excess fat in your waist and abdomen. Under this premise, it is easy to do. There are many ways to exercise the abdomen. I won't go into details upstairs. Now the key is how to practice. First of all, you should make a plan: for example, do 6 groups every day from Monday to Saturday, and the first 3 groups do sit-ups with 20 in each group (of course, this depends on your physical fitness. Each group takes a break of 20-40 seconds, and takes a break of 2 minutes between the first action and the second action. Six groups will be performed the next day. The first three groups are supported by the bridge, and the last three groups are lifted in a prone position. The number of groups is the same as above, and two different movements will be changed on the third day. Repeat on the fourth day and rest on the seventh day. The effect of this is to fully stimulate your abdominal muscles in different positions and postures, so as to better coordinate your muscles. When you think you can finish these actions easily, you need to change your plan. Then don't count. Remember, don't lie to yourself until each group can get up. Rest time can be extended!
2: If you are fat, it is useless for you to do more abdominal exercises. You must lose weight first and lose the fat on your waist and abdomen, which requires hard aerobic exercise!
