Stand up straight with a resistance band tied around both thighs, just above your knees.
With your legs hip-distance apart there should be tension in the band.
Place your hands on your hips.
Transfer your weight onto one leg and soften your knee a little.
With your back straight, allow your body to tilt forward a little, pushing your hips back behind you.
With your elevated knee bent, lift your thigh out to the side, rotating your leg outwards.
Ensure your body remains straight with your hips square, facing directly forward.
Activating your abdominal muscles will help you to control this.
Control the movement as you bring your leg back to the starting position, and repeat.
