Instructions

  1. 1Adjust the leg machine to a height that will allow you to get inside it with your knees bent and the thighs slightly below parallel.
  2. 2Once you select the weight, position yourself inside the machine face up with the knees bent and thighs slightly below parallel to the platform. Make sure that the knees do not go past the toes. The angle created between the hamstrings and the calves should be one that is slightly less than 90 degrees (since your starting position requires you to start slightly below parallel). Your back and your head should be resting on the machine while your shoulders are pressed under the shoulder pads.
  3. 3Place your hands by the handles and position your feet slightly pointing out at a shoulder width position. This will be your starting position.
  4. 4While pressing with the balls of the feet as you breathe out, make your whole body erect as you squeeze the quads. Hold the contracted position for a second. Tip: Since you are starting below parallel, you can opt to use your hands to help you up by pressing on your thighs only on the first repetition.
  5. 5Slowly squat down as you inhale but instead of going all the way down to the starting position, just stop once your thighs are parallel to the platform. The angle between your hamstrings and calves should be a 90-degree angle.
  6. 6Repeat for the recommended amount of repetitions.

About Lying Machine Squat

The lying machine squat mirrors a classic squat movement but performed lying on your back inside a guided machine. With your feet on the platform, you bend the knees to bring the thighs below parallel, then push back to the starting position without ever fully locking out the knees. The machine's guided path removes any balance demand, letting you focus entirely on quad contraction and load heavy safely. It's a solid alternative to the barbell squat for people who struggle with trunk bracing while standing, or who want to isolate leg work further without stressing the lower back. This exercise pairs well with free-weight squats or the leg press in a program focused on quad development.

helpFrequently asked questions

Does this replace the barbell squat?expand_more

It targets the same muscles but without the balance and bracing demand; the two work well together.

Why shouldn't I lock out my knees?expand_more

To keep tension on the quads and avoid shifting stress onto the knee joint.
