Setup
- Lie flat on your back on a mat with your legs fully extended and feet together.
- Place your hands flat on the floor by your sides or tucked slightly under your glutes for extra lower back support.
- Press your lower back firmly into the floor to engage your core and eliminate any arch in your spine.
How to do it
- Exhale as you lift your legs toward the ceiling, keeping them as straight as possible, until they are perpendicular to the floor.
- Inhale as you slowly lower your legs back toward the floor using a controlled 3-second tempo.
- Stop the descent just an inch before your heels touch the ground to maintain constant tension on the abdominals.
Form checklist
- Keep your lower back glued to the floor throughout the entire movement.
- Maintain a slight, soft bend in the knees if your hamstrings feel tight.
- Avoid using momentum or swinging your legs to lift them.
- Keep your neck and shoulders relaxed on the mat to avoid strain.
Pro tips
- Focus on tilting your pelvis toward your ribs as you lift to maximize lower abdominal recruitment rather than just moving your legs.
- Imagine pushing your heels away from your body throughout the movement to keep the legs long and the core fully engaged.
Make it harder
- Perform the exercise with your hands behind your head to remove the stability provided by the floor.
- Add a 'hip pop' or vertical pelvic thrust at the top of the movement to further engage the deep core.
