Ardha Salabhasana (Half-Locust Posture)
1. Lie face down on the floor, the arms by the sides, palms up, the legs together.
2. The chin rests on the floor. Take a deep breath and raise the straight left leg as high as possible. Only the left leg moves. Hold the leg up for ten to fifteen seconds. Lower the left leg, exhaling.
3. Rest a few seconds, and then raise the right leg.
Benefits: The lower back is strengthened, the legs are firmed, and the abdomen and its organs are toned by the pressure on the floor.
