HOW TO DO CABLE LEG EXTENSION

  1. Attach an ankle cuff to the low pulley and sit on a stable bench with the cable behind you, or stand with the thigh held still.
  2. Begin with the working knee bent, straighten it until the leg is long without snapping the joint, then return slowly.
  3. Keep the thigh, pelvis, and trunk steady so the motion comes primarily from the knee.
  4. Avoid swinging the whole leg or choosing a position where the cable pulls the cuff down the ankle.
  5. A seated setup is usually easier to stabilize; adjust bench distance and pulley height so resistance remains smooth and use only a range your knee tolerates.
