Abdominal breathing is to bulge the abdomen when inhaling and tighten the abdomen when exhaling. This is the most basic training for people who practice yoga or vocalization. The advantage of abdominal breathing is that it can stimulate gastrointestinal peristalsis and promote the discharge of waste in the body, thus making the air flow smoothly. When we usually walk or stand, we can make the muscles of the lower abdomen strong as long as we close our abdomen and cooperate with abdominal breathing.

Hands naturally lie flat on your sides, palms facing down. Then lower your left leg in two steps, starting from your hips and touching your toes, but not your toes. Then exhale, return the leg to the starting position in two steps, and then change the right leg to do the same action. Repeat this action alternately with both legs, and each leg repeats 12 times.

The main part of supine alternate method is ventrolateral muscle. First, put your hands behind your neck and bend your legs. Then kick out your legs alternately.

One elbow and the other knee should be as close as possible and controlled by the lateral abdominal muscles. Push each leg at least 15 times, a total of three groups.
