Seated Russian Twist
This classic move targets your obliques, and adding a dumbbell or medicine ball increases the challenge.
- Holding a dumbbell in both hands, sit on the ground with your knees bent and your heels about a foot from your butt. You can also make the move more advanced by lifting your feet three or four inches off the floor, as pictured.
- Lean slightly back without rounding your spine at all. It is really important, and difficult, to keep your back straight.
- Pull your navel to your spine, and twist slowly to the left, bringing the weight to your left side. 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.
