Trikonasana (The triangle pose)
Stand erect. Then keep your legs wide apart, say, a little more than your shoulder width. Inhale and raise your right hand parallel to the ear. Make a full stretch of your hand upwards. Now exhale and bend your torso to the left side. At the same time, slide downs your left arm alongside your left leg to reach the ankle.
Now your right arm is horizontal and in line with your head. While holding this position ensure that both knees and both arms remain straight. Stay in the position for thirty seconds in the beginning. Later you can extend it up to two minutes. Inhale and return to the standing position. Repeat the exercise on the other side.
Benefits: A good exercise for the whole body. Muscles in the hip and chest region are greatly benefited. Reduces lower back pain. A good warm-up exercise to improve general health.
