The leg extension is a resistance weight training exercise that targets the quadricep muscle in the legs. The exercise is done using a machine called the Leg Extension Machine. There are various manufacturers of these machines and each one is slightly different. Most gym and weight rooms will have the machine in their facility. The leg extension is an isolated exercise targeting one specific muscle, the quadricep. It should not be considered as a total leg workout, such as the squat or deadlift.


WARNING: Each gym's leg extension machine will be different. Make sure you understand how to use your gym's equipment before attempting the exercise.

  1. Adjust the seat so that the small of your back rests flush against 
     it and your knees are in line with the pivot point of the pulley.
  2. Adjust the foot pad so it rests slightly above your foot at ankle level.
  3. Firmly grasp the handles by the seat.
  4. Face forward and keep your chest out.
  5. Extend legs until they are horizontal with the floor and keep your back pushed into the seat.
  6. Slowly lower legs until they are back to starting position.
