Lie down on right side of body.
Place back of head on right hand—point right elbow at top of mat.
Make a straight line from right elbow to hips, from hips to feet.
Grasp left big toe with first two fingers and thumb of left hand or hold outside edge of left foot—arm inside leg.
Stay here or straighten left leg (more difficult: stack hips, be as sideways as possible).
Press outer edge of right foot into floor, lift ankle.
Press fingers and big toe together.
Tone thighs, tighten kneecaps, firm hamstrings.
Press bottom elbow down, lift shoulder up.
Engage glutes, press tailbone in, tone abdomen.
Repeat on the second side.
If you stack hips, endless pose can be among the more difficult balancing poses. This pose can be a good alternate to v sage (vasisthasana).
