Binding foot type:
Pay attention to the stretching of the back. If your back can't stand upright, put a yoga blanket or brick under your hips. Don't pull your feet too close to your body, focus on stretching the inner thigh to enhance the strength of this part of the muscle.
Lying on your side:
Starting from the right, head rest on the right arm, legs together, knees bent 90 degrees. Inhale and slowly lift the left leg knee, put your feet together until the knees are about one palm apart, keep breathing for several times, and slowly fall when exhaling.
