Leg Press
The leg press is a machine squat: you sit in a sled, push a loaded platform away with your legs and lower it back under control. It trains the quads first, with the glutes and adductors helping, and lets you load your legs heavily without balancing a bar on your back. It is also the leg exercise Muscla gives new lifters in the gym first.
How to do the leg press
Sit in the sled with your back and hips flat against the pad and your head resting on it.
Place your feet in the middle of the platform, about hip to shoulder width apart, toes turned out slightly.
Push the platform up, release the safety catches and hold the handles beside the seat.
Bend your knees and lower the sled under control, knees moving in line with your toes.
Go as deep as you can while your hips and lower back stay on the pad.
Press through your whole foot until your knees are straight but not snapped back, then start the next rep.
Seat and sled setup for the leg press
If the backrest adjusts, set it so you can bend your knees deeply without your hips lifting; a more upright back shortens the range you can use. Sit with your back and hips flat against the pad and your head resting on it. Load the sled evenly on both sides, and before every set check that you can reach the safety catches and lock them again when you finish.
Foot position on the leg press
Put your feet in the middle of the platform, about hip to shoulder width apart, with your toes turned out a little. Your whole foot stays flat, and your knees point the same way as your toes. Moving the feet lower on the platform lets your knees travel further forward and puts more of the work on the quads; moving them higher lets your hips bend more and brings the glutes in. Pick one position and keep it, so your weights stay comparable.
Bracing and breathing
Hold the handles, press your back into the pad and take a breath before you lower the sled. Keep the air in through the bottom of the rep and breathe out as you pass the hardest part on the way up or at the top. Your trunk stays still for the whole set; only your hips, knees and ankles move.
Depth, tempo and lockout
Lower the sled under control until your thighs come close to your chest or your hips are about to lift, whichever comes first. Turn around without bouncing and press with intent through your whole foot. Finish each rep with straight but soft knees and start the next one right away, so the tension stays on your legs. Use the same depth on every rep, because only comparable reps tell you when to add weight.
Muscles worked by the leg press
- Primary
- Quads
- Secondary
- Glutes
- Adductors
The quads straighten your knees and do most of the work. The glutes extend the hips, most in the deep part of the rep, and the adductors on the inside of the thigh help. Foot position shifts the balance: in an EMG study, a low foot placement raised quad activity, while a high placement raised glute activity. Turning the toes straight or out made no difference to muscle activity in another study, so choose the angle that suits your knees and hips.
Common leg press mistakes
Letting the hips roll off the pad
When your tailbone curls up at the bottom, your lower back rounds under the load. Stop the descent just before that happens, even if it is higher than you would like.
Letting the knees cave in
Knees that drift toward each other on the way up take the hips out of their share of the work. Push them out in line with your toes for the whole rep.
Snapping the knees into lockout
Slamming into straight legs at the top ends each rep with a jolt instead of control. Finish smoothly, with the knees straight but not forced back.
Pushing through the toes
Lifting the heels shifts the pressure onto the front of the foot and the knees travel forward. Keep your whole foot flat and press through the middle of it.
Piling on plates for short reps
A huge load moved a few centimetres looks impressive but makes your log useless, because each rep is a different lift. Use a depth you can repeat on every rep.
How Muscla coaches the leg press
- Warm up with two ramp sets: about 50% of your working weight for 8 reps, then about 75% for 3. Muscla adds them to every heavy compound lift.
- End working sets with about two reps in the tank, two to three when you train for strength and one more if you are new to training.
- Rest 3 minutes between sets for strength, 2 minutes for muscle and 90 seconds otherwise. In trained men, 3-minute rests built more strength and muscle than 1-minute rests.
- Add weight once every set reaches the top of your rep range. Muscla steps lower-body lifts by about 5%, rounded to the machine's grid of 5 kg or 10 lb: at 200 kg the next step is 210 kg.
- After the last set, Muscla asks “How heavy was that?” Light adds weight, Good keeps the normal progression, Heavy holds it, At the limit holds it or takes off one step.
Leg press sets, reps and rest
| Goal | Reps | Rest |
|---|---|---|
| Strength | 3–6 → 2–5 → 4–8 | 3 min |
| Muscle | 6–10 → 8–12 | 2 min |
| Lose fat | 6–12 | 90 s |
| Fit | 8–12 | 90 s |
| Comeback | 8–12 | 90 s |

Muscla counts the leg press as a heavy compound lift, so it uses the ranges for heavy squats and presses and the longest rests. It is the squat pattern new lifters get first in the gym, and Muscla never puts it on the same day as another squat variation.

Leg press questions
Is the leg press as good as squats?
For building your legs, it is a strong choice. In a 10-week study, squats raised the squat one-rep max more than the leg press did, while both improved functional tests, so the strength you build is partly specific to the exercise you train.
Where should I put my feet on the leg press?
In the middle of the platform, about hip to shoulder width apart, is a good default. In an EMG study, a lower foot placement raised quad activity and a higher placement raised glute activity, so you can shift the work with small changes.
How deep should you go on the leg press?
As deep as your hips and lower back stay on the pad. In trained lifters, leg presses to about 100 degrees of knee bend built as much quad muscle over 8 weeks as presses through each lifter's full range, so you do not need to force extra depth.
How much should a beginner leg press?
Muscla's first suggestion for a man new to training is about his body weight: 80 kg at 80 kg body weight. For a woman new to training at 65 kg it is 55 kg. Your first working set then corrects it.
Does the leg press work the glutes?
Yes, they help extend the hips, most in the deep part of the rep. Placing your feet higher on the platform raised glute activity in an EMG study.
