Lie on your back, with knees bent and feet off the floor at 90 degrees. Keep your hands under your neck and head for support. Your elbows should be out to the side. Tighten the tummy muscles as if you are trying to use the toilet!

DON'T suck your tummy in or hold your breath.

Lift your shoulder blades off the floor as you simultaneously curl your hips off the floor, squeezing the abdominal muscles even harder. SLOWLY lower to your starting position, but don't let your head or feet touch the floor. Do remember to keep your chin off your chest.

After 12 repetitions, rest and repeat.
