Incline Sit-up + Rotation 1
The incline sit-up plus rotation 1 is a variation of the incline sit-up with rotation that emphasizes a momentary hold at the rotated top position. The pause increases time under tension in the obliques and abs, enhancing the muscle activation compared to a continuous-flow version.
How to do it
- Lie on an incline bench with your feet secured and your hands behind your head.
- Curl your torso upward into the sit-up.
- At the top, hold the rotation to one side for a beat before lowering.
- Alternate the direction of rotation each repetition.
- Repeat for the desired number of repetitions.
Form cues
- Keep your hands gently behind your ears without pulling on your neck.
- Exhale as you curl your torso upward.
- Pause and hold the twist firmly at the top.
- Lower down with control rather than dropping quickly.
Breathing: Exhale as you curl up and rotate, and inhale as you lower your torso back down to the bench.
Common mistakes
- Pulling on the head with your hands, which strains the neck muscles.
- Rushing through the top rotation, which reduces time under tension for the obliques.
- Using momentum to bounce up instead of relying on core strength.
Muscles worked
Primary: abs. Secondary: obliques, hip flexors.

Why do I feel this more in my hip flexors than my abs?
Incline sit-ups naturally involve the hip flexors. To shift the focus back to your core, focus on curling your ribcage toward your hips rather than just sitting straight up.
How many times a week should I do this exercise?
2 to 3 times per week is plenty for most beginners, allowing your core muscles adequate time to recover between sessions.
Can I do this without an incline bench?
An incline bench provides the specific angle needed for this variation, but you can try floor-based twisting crunches if you do not have bench access.
