Lever Leg Extension

Muscles worked

Setup

1. Adjust the backrest so your knees align perfectly with the machine's pivot point (axis of rotation).
2. Position the lower leg pad just above the ankles, ensuring it rests comfortably against your shins.
3. Sit firmly against the backrest and grasp the side handles to stabilize your upper body.
4. Place your feet hip-width apart with toes pointing forward or slightly upward.

How to do it

1. Exhale as you extend your legs fully by contracting your quadriceps, moving in a smooth, controlled arc.
2. Squeeze your quads hard at the top of the movement for a one-second peak contraction.
3. Inhale as you slowly lower the weight back to the starting position using a 2-3 second tempo.
4. Stop just before the weight stack touches to maintain constant tension on the muscles.

Form checklist

• Keep your lower back and hips pressed firmly against the seat at all times.
• Avoid using momentum or 'kicking' the weight up; maintain a steady speed.
• Ensure the movement occurs only at the knee joint while keeping the rest of the body still.
• Do not allow your glutes to lift off the seat during the peak of the extension.

Pro tips

• Pull yourself down into the seat using the handles to create a more stable base for higher force production.
• Focus on driving the back of your knees down into the seat cushion as you reach full extension to maximize quad recruitment.

Make it harder

• Perform the movement unilaterally (one leg at a time) to address strength imbalances and increase core stability.
• Add a 3-second pause at the top of each rep to maximize the peak contraction of the rectus femoris.
