Twist your way to a transformed tummy.

Lie on your back with your knees raised, hip–width apart. Bring one foot up and rest the ankle on the opposite thigh, just above the knee. Cradle your head in the opposite hand to the raised leg and place your other hand flat on your tummy. Let both elbows rest on the floor and take a deep breath. Then breathe out slowly as you come up into a curl. Twist your body as you curl by turning the shoulder of the arm supporting your head. Your elbow and ribcage should all be twisting as one in the direction of your raised knee. Don't pull forward, or you'll pull and strain your neck.

Return to the starting position and do 4–8 reps working up to of 8–16 reps on each side.

Nicki's Tip: Make sure you swap over and do an equal number of reps curling each way for a perfectly even tum.
