To create a good, athletic posture, position your feet no wider than shoulder-width apart (instep to instep) and flex your knees slightly. You want to feel a slight tension in feet, thighs and abdominal area as you bend gently from the hips while maintaining a flat lower back. Your body is now in a perfect posture, ready to move. When you work out with the Swing- Setter, I recommend that you place a ball or a coin on the ground to give you a point of reference - something to set-up to.
