- Intermediate
- Compound
- Rep-based

It isolates the core by minimizing lower body movement, making it highly effective for developing rotational strength and midsection definition.

Setup
- Sit on the end of a flat bench with your feet secured under a foot pad or pressed firmly against the floor for stability.
- Hold a single dumbbell with both hands at chest height using a neutral grip.
- Lean your torso back to approximately a 45-degree angle while keeping your spine neutral and chest proud.
How to do it
- Exhale and rotate your torso to one side, bringing the dumbbell toward your hip while keeping your elbows slightly flared.
- Inhale as you return to the center position with control, maintaining the 45-degree lean.
- Exhale and repeat the rotation to the opposite side, ensuring the movement originates from the waist.
- Maintain a controlled 2-second tempo for each rotation to avoid using momentum.
Form checklist
- Keep your lower back flat and avoid rounding the shoulders forward.
- Ensure your hips remain stationary on the bench throughout the movement.
- Follow the dumbbell with your eyes to encourage full thoracic rotation.
- Keep the dumbbell close to your body to maintain better control over the weight.
Pro tips
- Focus on 'wringing out' your midsection like a towel to maximize oblique recruitment.
- Imagine your ribcage rotating around your spine while your pelvis stays locked in place to ensure the core is doing the work.
Make it harder
- Pause for 2 seconds at the peak of the rotation to increase time under tension.
- Extend your arms further away from your body to increase the lever arm and rotational challenge.
