Firm your abs and obliques with this core-strengthening move.
The C-Curl: Lie on your back with your heels off the floor and knees bent 90 degrees. Keep your abs pulled in and your arms straight along your sides. Lift your upper body off the floor and curl your ribs towards your thighs into a gentle C shape. If you need to, hold the back of your thighs for support. Now tap your left toes down, then tap your right toes down. Do 20 taps on each side. Then lower your body all the way down to the floor. Rest for a breath. Come back up into your C, but this time twist your right shoulder to your left knee as you tap your toes down. Reverse the twist to the other side and tap your other foot down. Do 20 twists and taps on each side. Keep your arms straight along your side to engage more of your back muscle. This move works your abs and your obliques.
