Ardha halasana

Lie on the back, with feet together. Keep palms beside the thighs, palm facing downwards.
Inhale slowly and rise one leg, as much as possible, without bending the knees. Hold the
posture for 30 seconds, then bring it downwards slowly while exhaling. Relax for a while.
Similarly repeat on the other leg.
