Setup
- Adjust an incline bench to a 30-45 degree angle and secure your feet firmly under the foot pads.
- Sit on the bench with your knees slightly bent and your hips tucked close to the seat.
- Place your fingertips lightly behind your ears or cross your arms over your chest.
- Engage your core to maintain a neutral spine before beginning the descent.
How to do it
- Inhale as you lower your torso under control until your back is just a few inches above the bench.
- Exhale forcefully as you sit up, rotating your torso to bring your right elbow toward your left knee.
- Inhale as you lower back down to the starting position in a smooth, controlled motion.
- Repeat the movement on the opposite side, alternating the direction of the twist with each repetition.
Form checklist
- Rotate from the ribcage and shoulders rather than just pulling your elbow across.
- Keep your lower back slightly rounded to maintain constant tension on the abdominals.
- Avoid pulling on your head or neck with your hands.
- Maintain a slow, controlled tempo to eliminate momentum and maximize muscle fiber recruitment.
Pro tips
- Think about 'shortening' the distance between your bottom rib and the opposite hip bone during the twist.
- Pause for a half-second at the top of the movement to emphasize the peak contraction of the obliques.
Make it harder
- Hold a medicine ball or weight plate against your chest to increase the load.
- Increase the steepness of the incline bench to create a longer lever and greater gravitational resistance.
