The abdomen is the core of a person. Walking and running need the support of abdominal muscles, so running can practice abdominal muscles, but it will not become real abdominal muscles. In addition, running for 30 minutes can reduce fat. If the body fat is above 10%, there will be no obvious abdominal muscles.

Abdominal muscles: 4 groups at each end.

Supine leg lifting group 4

Sit-ups 4 groups

The rest time of abdominal muscles in each group is 20 seconds to 30 seconds. Do it as soon as possible after recovery, and the number of each group should be tired.

Practice more than four times a week.
