Seated Russian Twist
Work your muffin top and tighten your core with this simple move.
- Sit with your heels about two feet from your butt, holding a dumbbell at your chest. Keeping your back straight, lean your entire torso back a few inches. You should feel your abs working to keep you upright.
- Without rounding your spine, rotate your ribcage to the left, then return to center to twist to the right. This completes one rep.
- Do 15 reps to complete a set.
Use five- to 15-pound dumbbells.
