If you want to thin belly, you should combine aerobic exercise.

In layman's terms, it is only effective to run for no more than 15 minutes.

In addition, the principle of sit-ups is a small number of times.

For example, if the goal you set for yourself today is to do 60, then don't do it all at once. You can do it three times, 20 at a time, with a pause of about 3 minutes.

The effective method is 3 to 5 groups a day. At the beginning, a group can be controlled at about 8, and gradually increase ~ ~

But don't overdo it, step by step.

If you finish on the first day and your abdominal muscles hurt the next day, it is suggested that you only need to run and do sit-ups less or not, otherwise you will be easily injured. Wait until the pain eases. As long as aerobic exercise is uninterrupted, you don't have to worry about giving up before the meeting.
