Dumbbell Russian Twist (on stability ball)

How to do the Dumbbell Russian Twist (on stability ball)

1. 1Sit on a stability ball, then walk your feet forward until your upper back and shoulders rest on the ball and your hips form a stable tabletop.
2. 2Plant your feet flat on the floor about hip-width apart and squeeze your glutes to keep your hips level.
3. 3Hold one dumbbell with both hands and press it straight up over your chest, arms nearly extended.
4. 4Brace your core and rotate your torso to one side, sweeping the dumbbell across your body while keeping your hips facing the ceiling.
5. 5Pause briefly when the dumbbell reaches the side, feeling the obliques work.
6. 6Rotate back through the center under control and twist to the opposite side.
7. 7Continue alternating sides for your target reps, moving with control rather than momentum.
8. 8Finish by bringing the dumbbell back to center and walking your feet back to sit up safely.

Form tips

• Drive the rotation from your trunk, not your arms — your hands and shoulders should move because your torso turns.
• Keep your hips lifted and steady throughout; let the upper body rotate while the lower body stays anchored.
• Exhale as you twist toward each side and inhale as you return to center to keep your core braced.
• Start with a light dumbbell to master balance on the ball before adding load.

Common mistakes

• Swinging the dumbbell with momentum, which takes tension off the obliques and turns the move into a sloppy arm swing.
• Letting the hips drop or rotate with the torso, which kills core engagement and can strain the lower back.
• Rushing through reps so the ball wobbles out of control, costing both stability and muscle tension.
• Holding your breath and losing the brace, which reduces trunk stability and makes the lift less effective.
