Inhale and come up to starting position.

If possible, touch the ground behind foot. Pull hip square against wall with left hand and turn head to look up.
Inhale and raise left arm straight up over head so that arms are in a straight line. Keep hips and torso against the wall as both arms stretch, one down and one up, touching the wall. Hold posture with smooth, even breathing for a slow count of 10. Inhale, come up and repeat on left.
Benefits: Trikonasana helps produce excellent spinal flexibility. It stretches the legs, back and neck and helps to loosen up the hips and make them strong and flexible. It is also, to some extent, a balance posture; in yoga, it is believed that the skill developed in physical balance has a profound effect on the mind, quieting unruly emotions and creating calm. It is one of the best postures for slimming the waist, hips, arms and legs. Remember to breathe deeply in when stretching up and breathe deeply out when bending the body downward.
