Machine leg press
The machine leg press is a compound lower-body exercise that targets the quadriceps, glutes, and hamstrings. It allows you to safely train the legs with heavy loads by eliminating the need to balance a free-weight barbell.

- Sit on the leg press machine and place your feet flat on the sled platform, roughly hip-width apart.
- Lower the safety bars and grasp the handles at your sides to keep your hips secured in the seat.
- Slowly lower the platform by bending your knees until they reach approximately a 90-degree angle, keeping your lower back flat against the pad.
- Push the platform away by extending your legs, driving through your entire foot rather than just your toes.
- Extend your legs fully but stop just short of locking out your knees, then repeat for the desired number of repetitions.

Form tips
- Keep your heels pressed firmly against the platform at all times to protect your knees and maximize power output.
- Maintain a tight core and press your tailbone firmly into the seat pad to prevent your lower back from rounding.
- Control the descent of the weight slowly to maximize time under tension and avoid bouncing at the bottom.
Common mistakes
- Locking out the knees at the top of the movement, which transfers the load from the muscles to the joint structures.
- Allowing the lower back or glutes to lift off the seat pad, which places severe compressive forces on the lumbar spine.
- Allowing the knees to collapse inward during the press, increasing the risk of ligament injury.
FAQ
How many reps and sets of the leg press should I do?
For muscle growth and strength, perform 3 to 4 sets of 8 to 12 repetitions using a weight that challenges you in that range while maintaining perfect form.
How does foot placement affect the muscles targeted?
Placing your feet higher on the platform shifts more focus to the glutes and hamstrings, while a lower placement increases the emphasis on the quadriceps.
Is the leg press a good substitute for squats?
Yes, it is an excellent alternative for building leg mass, especially for individuals with lower back limitations, though it does not recruit stabilizing core muscles as much as a free-weight squat.
