Left twist with left leg bent
Sit straight, straighten your legs and back. Bend your left leg and put your left foot near your right knee. Bend your right arm and move your right elbow behind your left leg. Pushing against your leg, try to grab your right leg at the knee level with your right hand. Press your left hand against the floor behind your back. Twist your backbone to the left around its axis as you exhale. Rotate your head to the left.
