Building Bridges - progress your pelvic tilt
Lie on your back, hands at your sides, knees bent, feet flat on the floor under your knees.
Contract your abdominal muscles and squeeze your bum cheeks.
Tilt your pelvis and raise your hips - you're aiming for a straight line from knees to shoulders.
Keep your abdominal muscles contracted
Slowly rolling down - return your body to the mat.
Try to do this 8 times in a row - do not worry if you can't. Build up to it!
Raise your hips too high - you'll hurt your back
Let your hips sag - remember you may need to build up your strength slowly.
