Russian twists are a great way to tone your abs, especially your obliques. You can do them without equipment, but for quicker results, try holding a dumbbell or adding a medicine ball at chest height. Watch this video for a few Russian twist variations, or follow these steps:
- Sit on the ground with your knees bent and your heels about a foot from your bum.
- Lean slightly back without rounding your spine at all. It is really important, and difficult, to keep your back straight, so don't let it curve.
- Place your arms straight out in front of you with your hands holding either side of the dumbbell. Your hands should be level with the bottom of your ribcage.
- Pull your navel to your spine, and twist slowly to the left. The movement is not large and comes from the ribs rotating, not from your arms swinging. Inhale through center, and rotate to the right. This completes one rep. Lift your feet off the ground for a more advanced variation.
- Do 16 full rotations.
