Setup
- Secure your feet firmly under the rollers of a decline bench and sit with your knees bent.
- Hold a weight plate with both hands, keeping it close to your chest or slightly extended for more challenge.
- Lean back until your torso is at a 45-degree angle to the bench, engaging your core to hold the position.
How to do it
- Rotate your torso to one side, moving the weight plate toward your hip while exhaling forcefully.
- Inhale as you return to the center in a controlled manner, maintaining the 45-degree lean.
- Rotate to the opposite side, ensuring the movement is driven by your midsection rather than just your arms.
- Maintain a controlled tempo, focusing on a 1-second rotation and a 1-second return to center.
Form checklist
- Keep your spine neutral and chest up; avoid rounding your lower back.
- Ensure your hips remain glued to the bench to isolate the rotation to the waist.
- Follow the weight plate with your eyes and head to ensure full thoracic rotation.
- Keep your core braced tightly throughout the entire set to protect the spine.
Pro tips
- Focus on 'wringing out' your midsection like a towel at the end of each rotation to maximize oblique recruitment.
- Extend your arms further away from your body to increase the lever arm, making the weight feel significantly heavier.
Make it harder
- Increase the decline angle of the bench to increase the gravitational resistance on your upper body.
- Add a 2-second isometric pause at the end of each rotation before returning to the center.
