Leg Press
The leg press lets you load the quads and glutes heavily without balancing a bar. Seated in the machine, you lower the sled toward your chest and press it away, which makes it a safe way to add leg volume.

How to do the leg press
- Sit with your back and hips pressed flat into the pad.
- Place your feet shoulder width apart in the middle of the platform.
- Release the safety handles and straighten your legs without locking your knees.
- Lower the sled under control, pushing your knees out over your toes.
- Stop when your knees reach about 90° or your hips start to lift off the pad, then press back up through your whole foot.
Form cues and common mistakes
The same coaching points MUSQ shows on the lifter in the app.
Foot Placement
Where the feet sit on the platform changes which muscles carry the rep.
Why it mattersA shoulder-width stance centred on the platform balances quad and glute involvement, while pressing evenly through the whole foot keeps the knees tracking cleanly.
Common mistakePlacing the feet too high, too low, or too narrow for a stable, evenly loaded press.
Do this insteadSet the feet shoulder-width apart, centred on the platform, and press evenly through the whole foot.
Knee Tracking
The sled's fixed path does not fix bad knee tracking — that is still on the lifter.
Why it mattersLetting the knees travel out in line with the toes keeps the load centred in the joint through the full range of the press.
Common mistakeKnees caving inward as the weight gets heavy, especially on the way up from the bottom.
Do this insteadPush the knees out over the toes through both the lowering and the press, matching the stance's natural angle.
Range of Motion
How far the sled lowers should be limited by the hips, not the platform.
Why it mattersLowering only until the hips are about to tuck under — the lower back rounding off the pad — keeps the load on the legs instead of the lumbar spine.
Common mistakeLowering the sled all the way down until the hips round off the seat pad to chase extra range.
Do this insteadLower until the knees reach roughly 90 degrees or the hips start to lift off the pad, whichever comes first, then press back up.
Top Lockout
The top of a leg press rep should stop just short of straight.
Why it mattersLeaving a slight bend in the knees at the top keeps tension on the quads and stops a heavy sled from snapping the knees back past straight.
Common mistakePunching the knees all the way straight and locking out at the top of every rep.
Do this insteadExtend the legs until they are almost straight, stopping just short of a hard lockout.
Back Position
The lower back has a job on a leg press: staying flat against the pad.
Why it mattersA back and hips that stay flush against the seat pad transmit the leg drive cleanly, instead of letting the pelvis rock under load.
Common mistakeLetting the hips shift or the lower back arch off the pad as the sled lowers.
Do this insteadKeep the hips and lower back pressed flat into the pad through the whole set.

Leg Press FAQ
Does foot position on the leg press matter?
Yes. Feet lower on the platform bias the quads; feet higher shift more work to the glutes and hamstrings. A wider stance brings in the inner thighs.
Should you lock your knees on the leg press?
No. Stop just short of a hard lockout so the load stays on your muscles instead of your knee joints.
Is the leg press as good as squats?
It builds the quads and glutes very well but trains less balance and core bracing. It works best alongside squats, or instead of them when squatting isn't an option.
