Back against the wall, body close, feet 30 cm away from the wall. Prepare for inhalation. When exhaling, the lumbar vertebrae cling to the wall, and then inhale and restore. Repeat 10~ 15 times for 2~3 groups. Be careful not to push your arms against the wall, your abdomen should be close to the wall actively, and you should feel your navel close to the wall.
Lie on your back and lift your legs.
Lie on your back, chin slightly retracted, legs supported by both hands, and lumbar vertebrae pressed on the mat. Prepare to inhale, push your right leg away when exhaling, and repeat 6~8 times. Change the other leg and repeat 2~3 groups. Try to press your leg against the chest and lumbar spine to hold down the mat, while keeping the other leg as straight as possible to keep the lumbar spine from lifting.
