This is the instructions for unilateral leg extension

  • 1. Set the load on the machine.
  • 2. Sit down at the bottom of the seat and back straight. Then place the front of your ankle under the cushions provided.
  • 3. While exhaling, extend your leg by unfolding your knee upwards and in the axis of the machine.
  • 3. Slowly release muscle tension to lower the cushion by bending the knee.
  • 4. Continue your series by repeating the movement.
