Lie with your back flat on an exercise mat with a short band just above your knees. Place your feet hip width apart and your toes slightly turned out. Ensure the heels of your feet are fairly close to your glutes and that your pelvis is tucked forward (ensuring you have no arch in your back whilst lying down). Focusing the tension in your glutes, drive your hips up to full hip extension, exhaling as you do so. Make sure to keep your heels pressed firmly into the ground and push your knees out against the band. Pause for a count of one when your hips reach full hip extension, keeping the tension in your glutes and then return with control to the start position, inhaling as you do so. Repeat
