Leg Press

Sit in the leg press machine with your back flat against the pad. Place your feet shoulder-width apart on the platform. Release the safety catches and lower the platform by bending your knees until they approach 90 degrees. Press back to the starting position without locking your knees.

Pro Tips

• Keep your lower back pressed into the pad throughout
• Do not lock out your knees at the top
• A joint-friendly alternative to barbell squats for older lifters

Muscles worked

Primary: Quadriceps (knee extension throughout the press) and gluteus maximus (hip extension — contribution increases with a higher foot placement and greater hip flexion depth). The leg press removes the axial loading of a barbell squat and the balance and stabilisation demands, allowing direct leg pressing with isolated loading.

Supporting: Hamstrings (stabilisation of the knee joint throughout), adductors (inner thigh stabilisation, especially at the bottom of the movement), calves (minor).

Common mistakes

Letting the lower back round off the pad: This is the most common and most problematic error. Allowing the pelvis to posteriorly tilt (lower back rounding away from the pad) at the bottom compresses the lumbar discs in a flexion position under high load. The lower back must stay in contact with the pad throughout the full range of motion.

Locking out the knees: Extending the legs to complete lockout transfers load from the quads to the joint structures. Stop just short of full extension on every rep.

Too much weight, too little range: Heavy leg presses with minimal depth (quarter presses) are common but counterproductive. Most of the quad and glute loading occurs in the bottom third of the range. Full depth — hips approaching 90 degrees of flexion — is necessary for the movement to be effective.

Foot placement confusion: Higher foot placement increases glute and hamstring involvement and reduces quad emphasis. Lower foot placement increases quad emphasis and is the standard for quad-dominant leg pressing. Choose placement to match the training goal.

Programming notes

The leg press is one of the most used lower body exercises in hypertrophy programmes because of its ability to load the legs with high volume without the axial loading and technical demands of the barbell squat. It allows near-failure quad training in a safe, controlled position.

Typical programming: 3–5 sets of 8–15 repetitions. In programmes where the barbell squat is the primary lower body exercise, the leg press serves as a volume-adding secondary movement. In programmes where squatting is limited (joint restrictions, no barbell access), the leg press can serve as the primary lower body compound exercise.

Frequently asked questions

Should the leg press replace squats, or is it just an accessory?

For most lifters, the leg press works best as a high-volume accessory alongside barbell squatting, not a direct replacement. The squat trains the full kinetic chain — trunk, hip, knee, and ankle — under load, developing strength that transfers broadly. The leg press removes axial loading and balance demands, which reduces stimulus to stabilisers and the core. That said, if you have joint restrictions, no barbell access, or are returning from injury, the leg press can serve as your primary lower body compound without apology — just programme it accordingly with higher volume and closer to failure.

How low should you go on the leg press?

Lower the platform until your hips reach approximately 90 degrees of knee flexion, or as deep as you can go while keeping your lower back flat against the pad. Going deeper increases range of motion and quad stretch under load, which is a key driver of hypertrophy. The limit is your individual hip structure and flexibility — the moment your lower back rounds away from the pad, you have exceeded your usable range. Prioritise depth over load until you can hit full depth consistently.

Does foot placement actually change which muscles are worked?

Yes, and the difference is meaningful. A lower, narrower foot position shifts emphasis onto the quadriceps because you achieve greater knee flexion and less hip extension. A higher, wider foot position increases the range of hip extension and brings the glutes and hamstrings into the movement more significantly. Neither placement is universally correct — match it to your goal. If you are using the leg press as a quad builder, go lower. If you want more posterior chain involvement or are working around knee discomfort, go higher.
