How to do the lying machine squat
- Adjust the leg machine to a height that will allow you to get inside it with your knees bent and the thighs slightly below parallel.
- Once 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.
- Place your hands by the handles and position your feet slightly pointing out at a shoulder width position. This will be your starting position.
- While 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.
- Slowly 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.
- Repeat for the recommended amount of repetitions.
Muscles worked
The prime movers are the quadriceps across the front of the thigh, which straighten the knee and, just as importantly, control it on the way back down.
Because more than one joint is moving, the work does not stay in one place: the calves control the ankle and hold the heel position; the glutes finish hip extension; the hamstrings assist hip extension and slow the knee down.

How this movement works
The working muscles shorten as they drive the load away from you, and more than one joint changes angle to do it. Load spreads down a chain instead of sitting on one muscle, which is why a compound push handles more weight than any single-joint alternative — and why joint position, not the muscle, is usually what fails first.
It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.
What you need
The machine fixes the path, removing the balance demand and letting you train close to failure without a spotter. The cost is the stabilising work a free weight would have made you do.

Difficulty
Listed at intermediate level. It assumes you already own the underlying pattern and can hold position under load — if the position breaks before the target muscle tires, drop back to a beginner variation until it does not.
