Leg Press: How Many Sets and Reps, and How to Progress

How many leg press sets and reps to run each week, how to pick your load with RIR, and a concrete eight-week plan for adding weight without stalling.

The leg press is one of the few exercises where you can push serious weight without your spine or your balance being the limiting factor. That makes it a solid way to add volume for the quads and glutes, either alongside squats or as the main movement if squatting is off the table for you. The open question is how much of it you need and how to keep the load climbing past the first month.

How many sets per week

Do not count the leg press in isolation. Count it as part of your total leg volume. For most people, 10 to 20 hard sets per muscle group per week is the range where growth happens, and the leg press usually takes up a third to half of that.

First 6 months of training: 3-4 working sets per week, across one or two sessions.
After a year: 6-8 working sets per week, split across two sessions (3+3 or 4+4).
Advanced: 9-12 working sets per week, which is roughly the ceiling before recovery starts to suffer.

Two sessions a week beat one session with the same total volume. Eight sets in a single day means the last two or three are done on already-fatigued legs, and those are the ones that give you the least back. Training three days a week? Split it 3+3+3.

How many reps

The leg press works across a wide rep range, but there is little point going below 5 reps. The machine does not reward maximal attempts, and the load on the knees and lower back climbs for no return.

6-10 reps: a weight that is easy to track week to week. Good choice for your first working set.
10-15 reps: the main range for muscle growth and the easiest one to hold technique in.
15-25 reps: use it on your last set if you want, but expect to be out of breath for 2-3 minutes afterwards.

A practical layout for one session: three working sets, the first at 8 reps, the second at 10-12, the third at 12-15, dropping the weight 10-15% between sets if you need to.

How close to failure

Use RIR, reps in reserve: how many more reps you could have done when you racked the set. Run your early sets at RIR 2-3 and the last one at RIR 0-1. True failure on this machine means the sled stops halfway up, and you feel that in your knees and your recovery for weeks, with no extra benefit to the muscle.

Warm-up and rest

Empty sled or the lightest plate, 15 reps through a full range.
50% of working weight, 8 reps.
75% of working weight, 5 reps.
90% of working weight, 2-3 reps, then rest 2 minutes and start your first working set.

Rest between working sets: 2-3 minutes for sets of 8-15 reps, up to 4 minutes if you are working below 8. Sixty-second rests do not buy you more growth, they just cut the weight you can handle on the next set.

How to progress: double progression

Pick a range, say 10-15 reps, and three sets. You hold the same weight until all three sets reach the top of the range, and only then do you add load.

Week 1: 140 kg for 10, 10, 9.
Week 2: 140 kg for 12, 11, 10.
Week 3: 140 kg for 14, 13, 12.
Week 4: 140 kg for 15, 15, 15, so you add weight.
Week 5: 155 kg for 11, 10, 10 and the cycle restarts.

A jump of 10 kg, meaning 5 kg per side, is realistic here because the absolute loads on a leg press are large. If you are brand new, you will add 10-20 kg a week for the first 2-3 months. That is mostly you learning the movement rather than building muscle, so do not set your expectations by that pace.

When you stall two weeks in a row on normal sleep and food, drop the weight 10% and climb back the same way. After 6-10 weeks of progress, take one easy week: half the sets at 70% of the load.

One more thing: the number on the sled does not mean the same thing on two different machines. The 45-degree angle, the weight of the sled itself and the rails all differ, so compare yourself to last week rather than to someone else's numbers.

Technique details that actually matter

Feet: hip width or slightly wider, toes turned out 15-30 degrees, knees tracking over the toes.
Placement on the platform: feet lower means more quads, feet higher means more glutes and hamstrings. The difference is real but not dramatic, and it comes down to 5-10 cm either way.
Depth: lower until your pelvis is still flat against the seat. The moment your lower back starts peeling off and rounding, that is your range for today.
Lockout: stop 5-10 degrees short of full extension and never snap the knees straight under load.
Hands: on the handles, never on your knees.
Tempo: around 2 seconds down, no bounce at the bottom, controlled push back up.

When to see a doctor

Knee pain that lasts more than 2 weeks despite cutting the weight and the range of motion.
Knee swelling, the joint locking, or a sense of the leg giving way when you walk.
Pain radiating from your back down the leg, numbness, or weakness in the foot.
A bulge or groin pain when you strain, which can be a hernia.
Dizziness, heavy pressure in your head, or dark spots in your vision during a set, especially if you have high blood pressure. Get your blood pressure checked and stop holding your breath through the whole set.

If you are coming back from knee or hip surgery or a disc injury, agree on your range of motion and starting load with a physiotherapist before you start adding plates.

The short version

3-4 working sets a week if you are new, 6-8 at an intermediate level, 9-12 if advanced, split across two sessions.
Stay in the 6-15 rep range and rest 2-3 minutes between working sets.
Early sets at RIR 2-3, last set at RIR 0-1, with no chasing failure on every set.
Double progression: keep the weight until every set hits the top of the range, then add 10 kg.
Knee pain past two weeks, swelling, or numbness down the leg is a reason to see a doctor, not a reason to just go lighter.
