Equipment
Setup
- Adjust the backrest so your knees align perfectly with the machine's pivot point (axis of rotation).
- Position the lower leg pad just above your ankles, ensuring it rests comfortably against your shins.
- Sit back firmly against the pad and grasp the side handles to anchor your hips into the seat.
How to do it
- Exhale as you extend your legs upward in a smooth, controlled arc until your knees are fully straight.
- Squeeze your quadriceps hard at the top of the movement for a one-second pause.
- Inhale as you slowly lower the weight back to the starting position, maintaining tension on the muscles throughout the descent.
Form checklist
- Keep your lower back pressed firmly against the backrest throughout the set.
- Do not allow your hips to lift off the seat as you extend your legs.
- Avoid using momentum or swinging the weight; keep the movement fluid and controlled.
- Ensure your toes are pointing upward or slightly outward to maintain quad engagement.
Pro tips
- Pull yourself down into the seat using the handles to create maximum stability and prevent your body from shifting.
- Focus on the 'shortened' position of the quadriceps by emphasizing the peak contraction at the very top of the rep.
Make it harder
- Perform the exercise unilaterally (one leg at a time) to eliminate strength imbalances and increase core stability.
- Implement a 3-5 second eccentric (lowering) phase to maximize time under tension and metabolic stress.
