Setup
- Sit upright on the edge of a sturdy chair with your feet flat on the floor, hip-width apart.
- Grip the sides of the chair seat or the armrests firmly to stabilize your upper body.
- Engage your core and lift your chest, maintaining a neutral spine with a slight lean back for balance.
How to do it
- Extend both legs straight out in front of you until they are parallel to the floor, locking your knees.
- Exhale as you lift your straightened legs toward the ceiling as high as possible without rounding your lower back.
- Inhale as you slowly lower your legs back toward the floor using a controlled 2-second tempo.
- Stop just before your feet touch the ground to maintain constant tension on the abdominals.
Form checklist
- Keep your knees fully extended throughout the entire range of motion.
- Avoid shrugging your shoulders; keep them depressed and away from your ears.
- Ensure your lower back does not arch or round excessively as you lift your legs.
- Focus on moving only at the hip joint while keeping the rest of the body still.
Pro tips
- To maximize lower ab recruitment, focus on tilting your pelvis slightly upward as you reach the peak of the lift.
- Squeeze your quadriceps as hard as possible to create total leg tension, which helps stabilize the hip joint.
Make it harder
- Add a 3-second isometric hold at the top of each repetition to increase time under tension.
- Place a small weight, like a light dumbbell or a pillow, between your feet to increase resistance.
