Setup
- Lie flat on your back on a mat with your legs fully extended and feet together.
- Place your arms by your sides with palms down, or tuck your hands slightly under your glutes for additional lower back support.
- Engage your core by pressing your lower back firmly into the floor to eliminate any arching.
How to do it
- Exhale as you lift both legs together toward the ceiling, keeping them straight until they are perpendicular to the floor.
- Inhale as you slowly lower your legs back toward the starting position using a controlled three-second tempo.
- Stop the descent just before your heels touch the ground to maintain constant tension on the abdominal muscles.
Form checklist
- Keep your lower back glued to the floor throughout the entire range of motion.
- Maintain straight legs with knees locked to maximize leverage on the core.
- Avoid using momentum or swinging the legs to lift them.
- Keep your neck and shoulders relaxed on the mat to prevent strain.
Pro tips
- Focus on a posterior pelvic tilt by imagining you are pulling your belly button through the floor to maximize deep core engagement.
- Pause for one second at the bottom of the movement, where the lever arm is longest, to challenge your core's anti-extension strength.
Make it harder
- Add a 'hip pop' or vertical thrust at the top of the movement to increase lower abdominal recruitment.
- Slow down the eccentric (lowering) phase to five seconds to increase time under tension.
