Leg Press: How to Do It, Muscles Worked
The Leg Press is a beginner-level strength exercise that primarily works the quadriceps, with the calves, glutes, hamstrings as secondary muscles. It uses machine, and is performed in 5 steps, following the form cues, common mistakes and sets/reps guidance below.
What muscles does the Leg Press work?
The Leg Press primarily targets the quadriceps, and also recruits the calves, glutes, hamstrings as secondary muscles. It's classified as a beginner-level strength movement using machine.
What are the most common Leg Press mistakes?
- Cutting the rep short at the top or bottom instead of using the full stretch and contraction.
- Speeding through the eccentric (lowering) phase instead of controlling it.
- Swinging the weight with body momentum instead of moving it under muscular control.
- Using a heavier weight than can be controlled through a full range of motion.
How should I program the Leg Press — sets, reps and frequency?
As a single-joint isolation exercise, it responds well to a higher 10-15 reps for 2-4 sets, usually taken close to muscular failure. It tolerates higher frequency than a heavy compound lift — twice a week for the same muscle group is common. Add small amounts of weight or an extra rep once every working set can be completed with good form — the same progressive overload principle behind every strength exercise in the library.

How to do the Leg Press, step by step:
- Step 1. Using a leg press machine, sit down on the machine and place your legs on the platform directly in front of you at a medium (shoulder width) foot stance. (Note: For the purposes of this discussion we will use the medium stance described above which targets overall development; however you can choose any of the three stances described in the foot positioning section).
- Step 2. Lower the safety bars holding the weighted platform in place and press the platform all the way up until your legs are fully extended in front of you. Tip: Make sure that you do not lock your knees. Your torso and the legs should make a perfect 90-degree angle. This will be your starting position.
- Step 3. As you inhale, slowly lower the platform until your upper and lower legs make a 90-degree angle.
- Step 4. Pushing mainly with the heels of your feet and using the quadriceps go back to the starting position as you exhale.
- Step 5. Repeat for the recommended amount of repetitions and ensure to lock the safety pins properly once you are done. You do not want that platform falling on you fully loaded.
Key takeaways
- The Leg Press is a beginner-level strength exercise using machine.
- Primary muscles worked: Quadriceps; secondary: Calves, Glutes, Hamstrings.
- A typical working range is 10-15 reps for 2-4 sets, usually taken close to muscular failure.
- The most common technical fault is cutting the rep short at the top or bottom instead of using the full stretch and contraction.

Is the Leg Press suitable for beginners?
Yes — the dataset lists the Leg Press as a beginner-level movement, though anyone new to training should still start with light weight (or no added weight) to learn the pattern first.
What equipment do I need for the Leg Press?
A machine. No other equipment is required for the standard version of this movement.
What's the difference between the primary and secondary muscles listed?
Primary muscles (Quadriceps) do most of the work and are usually the limiting factor in the set. Secondary muscles (Calves, Glutes, Hamstrings) assist or stabilize but aren't the main driver of the movement.
