Vertical Sit-Up
- Intermediate
- Compound
- Rep-based
- Waist
The Vertical Sit-Up performed on a hyperextension bench provides an extended range of motion that challenges the rectus abdominis through a deeper stretch and intense contraction. This variation heavily recruits the hip flexors and core stabilizers to maintain control against gravity.

Setup
- Position yourself on a hyperextension bench with your heels securely locked under the foot pads.
- Sit upright so your glutes are supported by the pad but your torso is free to move backward.
- Cross your arms over your chest or place your hands lightly behind your ears, ensuring you do not pull on your neck.
How to do it
- Inhale and slowly lower your torso backward in a controlled arc until your body is parallel to the floor or slightly below.
- Exhale and contract your abdominals to curl your torso back up toward the starting vertical position.
- Maintain a steady 2-1-2 tempo: two seconds to lower, a brief pause at the bottom, and two seconds to rise.
Form checklist
- Keep your chin tucked slightly toward your chest to maintain a neutral cervical spine.
- Focus on 'curling' the spine segment by segment rather than hinging purely at the hips.
- Avoid arching your lower back excessively at the bottom of the movement.
- Ensure your feet remain firmly hooked under the pads to stabilize your lower body.
Pro tips
- To maximize abdominal recruitment, focus on pulling your ribcage toward your pelvis during the upward phase.
- Pause for a full second at the bottom of the movement to eliminate momentum and force the core to initiate the lift.
Make it harder
- Hold a weight plate or dumbbell against your chest to increase resistance.
- Extend your arms straight overhead to increase the lever arm, significantly raising the difficulty for the core.
Frequently asked
- What muscles does the vertical sit-up work?
- The vertical sit-up primarily targets the abs and obliques, and also works the erector spinae as secondary muscles.
- What equipment do you need for the vertical sit-up?
- The vertical sit-up requires no equipment — just your body weight.
- Is the vertical sit-up good for beginners?
- The vertical sit-up is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
