Lie on your back with your knees bent and feet flat on the floor.
Ensure your feet and knees are hip-distance apart.
Tighten your buttock and abdominal muscles as you lift your hips up into a bridge position.
There should be a straight line from your shoulders to your knees.
With your weight in the heels of your feet, start alternately walking one foot, and then the other foot away from your buttocks.
Ensure you keep your hips up as high as you can, and your abdominal muscles activated.
Relax your upper body and shoulders.
At the point your knees are almost straight, alternately walk your feet back into the starting position and repeat.
