Setup
- Sit upright on the edge of a sturdy chair with your feet flat on the floor, hip-width apart.
- Engage your core and maintain a tall, neutral spine without leaning against the backrest.
- Grip the sides of the chair seat lightly with your hands for balance.
How to do it
- Exhale as you slowly lift one leg straight out in front of you until it is parallel to the floor.
- Squeeze your quadriceps at the top of the movement and hold for a brief second.
- Inhale as you lower the leg back down with control, stopping just before your foot touches the floor.
- Perform the desired number of repetitions on one leg before switching to the other.
Form checklist
- Keep your torso stationary; do not lean back as the leg rises.
- Ensure the knee of the working leg remains fully locked to maximize quad activation.
- Maintain a proud chest and avoid rounding your shoulders forward.
- Keep your hips level on the chair throughout the entire set.
Pro tips
- Flex your toes toward your shin (dorsiflexion) to create more tension throughout the front of the leg.
- Focus on initiating the lift from your lower abs and hip flexors rather than just swinging the foot up.
Make it harder
- Pause for 3-5 seconds at the top of each rep to increase time under tension.
- Perform the movement with ankle weights or a small resistance band looped around your feet.
