You can also bring your palms together over your head. While you do this, make sure your shoulders are not hunched. If your palms are apart, then they must face each other. Your arms must be straight at all times such that they are activated all throughout, till your frngertips. Move your gaze upwards. Your shoulders must be away from your ears, and your shoulder blades must be pressed firmly on your back. Your thighs should be engaged in such a way that they pull the kneecaps up. Straighten your legs, but do not lock your knees.
