First of all, we should carry out breathing training and adopt abdominal breathing. First of all, you must learn to breathe correctly before you can exert your strength.
Here's a trick to exercise your upper abdomen, called Bai Pai:
Step 1: Find a yoga mat and lie flat. After proper breathing training, the knees are raised, the knees are directly above the pelvis, the toes are close together, and the calves are kept parallel to the ground.
Step 2: slowly roll up the upper abdomen. Cross your hands behind your head, exhale from the sternum to drive the trunk to roll up slowly, hold your legs with your hands, pull up your body, and put your hands on your sides. At this time, exhale 5 times and inhale 5 times, and at the same time, use the breath to drive the arm to flap and lie down with your legs. Breathe 5 times 10 times, one hundred times as a group, three to five times a day, lasting for three months.
