About this exercise

A machine-based isolation exercise that extends the knee against a padded lever arm to target the quadriceps with minimal involvement from other muscle groups. The seated position keeps the hip flexors shortened, making it particularly effective for achieving a strong peak contraction at full extension.

How to Perform

  • Sit on the leg extension machine with your back flat against the pad and the ankle roller positioned just above your feet
  • Adjust the seat so your knees align with the machine's pivot point
  • Grip the handles on the sides of the seat for stability
  • Exhale and extend both legs until they are fully straightened, squeezing the quadriceps at the top
  • Hold the peak contraction briefly, then slowly lower the weight back to the starting position
  • Avoid swinging or using momentum to lift the weight

About the Lever Leg Extension

The Lever Leg Extension is a foundational movement that builds strength and muscle through controlled, progressive overload. Train it 1 to 2 times per week with 3 to 5 working sets per session, gradually adding weight or reps as form holds up.
