Setup
- Secure your feet firmly under the padded rollers of an incline bench set to a 30-45 degree angle.
- Sit upright holding a single dumbbell with both hands at chest height.
- Lean your torso back until it is approximately parallel to the floor or at a 45-degree angle to the bench to engage the core.
How to do it
- Rotate your torso to one side, bringing the dumbbell toward your hip while keeping your hips and legs locked in place.
- Exhale forcefully as you reach the end of the rotation, focusing on the contraction in your obliques.
- Inhale as you rotate back through the center and immediately transition to the opposite side in a controlled, fluid motion.
- Maintain a steady tempo, avoiding the use of momentum to swing the weight.
Form checklist
- Rotate from the ribcage and waist rather than just moving your arms side to side.
- Keep your chest up and shoulders back to avoid excessive rounding of the spine.
- Ensure your lower back remains stable and does not arch away from the bench.
- Follow the dumbbell with your eyes to maintain neutral neck alignment throughout the rotation.
Pro tips
- Focus on the 'mind-muscle connection' by imagining you are wringing out your midsection like a towel at the peak of each turn.
- Keep the dumbbell slightly away from your body to increase the lever arm, making the rotational load heavier for the obliques.
Make it harder
- Fully extend your arms straight out in front of your chest to maximize the torque on your abdominal wall.
- Pause for two seconds at the end of each rotation to eliminate momentum and increase time under tension.
