Russian Twists

How to do it

1. Sit on the floor with your knees bent, leaning back slightly so your torso forms a V with your thighs.
2. Lift your feet a few inches off the floor if you want more challenge.
3. Clasp your hands together in front of your chest.
4. Rotate your torso to one side, bringing your hands beside your hip.
5. Twist smoothly to the other side, keeping your chest lifted.
