The combination of sit-ups and aerobic exercise, first of all, for people with a lot of fat, can not rely solely on sit-ups. Do moderate aerobic exercise (running, skipping, swimming, etc.). Ensure that the daily intake of capacity is less than the energy consumed, so as to ensure the consumption of fat, and then assist sit-ups. At this time, it is best to exercise the abdominal muscles below the navel, which requires gradual and continuous exercise.

Several effective methods:

1, you must run, jogging with sprinting for more than 40 minutes every day.

2. If you have no conditions or don't want to go out, you can run for more than 45 minutes.

3, sit-ups, 3-5 groups a day, 30 in each group, remember not to just do sit-ups, otherwise the abdominal muscles below the navel are there, and you can't see the lines without sebum.
