Yoga for hips and shoulders. In Happy Hips and Shoulders Yoga we stretch the muscles, tendons and ligaments around the hips and shoulder girdle then move into strengthening the muscles around the shoulders bringing a balance to the upper and lower halves of the body. You may notice a difference after the first class but give a month or so and you will notice a difference not only in sustaining poses on your mat in various classes but off the mat in your daily routine as well.
