After practicing this stretch regularly you should notice that your increased flexibility allows you to press your knees easily to the ground.
Whether dancing to classical, modern, jazz or hip-hop music, dancers require a tremendous amount of strength and flexibility to bring the music to life through their bodies. Although your daily life may not require you to lift your leg toward the sky or bend over backwards, dance stretches to increase flexibility can help you avoid injury in your regular activities.
The butterfly stretch is used to elongate the muscles in the groin and inner thigh. Initiate the stretch by sitting on the floor with your feet flat against the ground. Allow your knees to fall to the sides and press the soles of your feet together. Pull your heels as close to your groin as possible without causing discomfort. Keeping your back straight, gently bounce your knees up and down to loosen the muscles.
