Variations of 3/4 Sit-up

How to do 3/4 Sit-up
- 01Setup
Lie on your back with your knees bent, feet flat on the floor hip-width apart, and hands lightly placed behind your head or crossed over your chest.
- 02Setup
Engage your core by gently pressing your lower back into the floor, ensuring there's no arch in your lumbar spine.
- 03
Exhale and slowly curl your head, neck, and shoulders off the floor, initiating the movement by contracting your abdominal muscles.
- 04
Continue to lift your upper body until your shoulder blades are just clear of the floor, focusing on a controlled spinal flexion rather than a full sit-up.
- 05
Inhale and slowly reverse the movement, lowering your upper body with control back to the starting position, maintaining tension in your core.
Tips
- Keep your gaze directed towards the ceiling throughout the movement to help maintain a neutral neck position and prevent strain.
- Focus on "crunching" your ribs towards your hips, ensuring the movement comes from your abdominal muscles rather than just lifting your head.
- Control the eccentric (lowering) phase of the movement to maximize time under tension and enhance muscle growth and strength.
- Avoid using your hands to pull your head up; they are there for gentle support, not to initiate or assist the lift.
Common mistakes
- Pulling on the neck: Pulling your head forward with your hands strains the cervical spine; instead, keep your gaze up and allow your abdominal muscles to lift your torso.
- Lifting too high: Coming up too far releases tension from your abdominal muscles; stop the upward movement when your shoulder blades are just off the floor to keep constant core engagement.
- Rushing the movement: Using momentum to complete repetitions reduces abdominal activation; perform each repetition slowly and deliberately, focusing on the contraction and control.
