Setup
- Sit upright on the edge of a sturdy chair or flat bench with your feet flat on the floor, hip-width apart.
- Grip the sides of the seat or place your hands behind your hips to stabilize your torso.
- Engage your core and maintain a neutral spine with your chest lifted and shoulders back.
How to do it
- Exhale as you slowly extend one leg forward until it is completely straight and parallel to the floor.
- Squeeze your quadriceps at the top of the movement and hold the contraction for one second.
- Inhale as you slowly lower the foot back to the starting position under full control.
- Repeat the movement with the opposite leg, alternating sides for the duration of the set.
Form checklist
- Keep your torso upright and avoid leaning back as you extend your leg.
- Ensure the movement is driven by the knee joint rather than swinging the hip.
- Keep your toes pointed toward the ceiling to maximize quadriceps engagement.
- Maintain a tight core to prevent your lower back from arching away from the chair.
Pro tips
- Focus on the 'peak contraction' of the quad at the top of the kick to maximize muscle fiber recruitment.
- Slow down the lowering phase (eccentric) to 2-3 seconds to increase time under tension for both the legs and abs.
Make it harder
- Perform the movement with both legs simultaneously to significantly increase the demand on the abdominal muscles.
- Add ankle weights or loop a resistance band around your ankles to provide constant tension throughout the range of motion.
