A Smith machine stands in for a sled here, its fixed vertical track guiding the press when your gym has no dedicated leg press station. The rigid path means alignment is entirely on you, so set your feet deliberately before unracking, because a slightly off position stays off for the whole set. Load conservatively compared with a true sled.
How to do the Smith Machine Leg Press
- Adjust the seat and footplate of the smith machine to a comfortable position.
- Sit on the machine with your back against the backrest and your feet shoulder-width apart on the footplate.
- Grasp the handles or sides of the machine for stability.
- Push the footplate away from you by extending your legs, keeping your back against the backrest.
- Pause for a moment at the fully extended position.
- Slowly bend your knees and lower the footplate back towards you, returning to the starting position.
- Repeat for the desired number of repetitions.
Tip: Push through the whole foot and keep your knees tracking in line with your toes rather than caving inward.
Muscles worked
Primary
Glutes · Legs
The glutes get more involved the higher and wider your feet are on the platform and the deeper you go.
Secondary
- Quads — The quads extend the knee and do most of the work, and they should feel it hardest in the bottom half of each rep.
- Hamstrings
- Calves — On a leg press calf raise, the calves push the platform away with the ball of the foot; go for a full stretch at the bottom and a slow lowering.
Common mistakes
- Lower back peeling off — if your hips lift at the bottom, the range is too deep for your hip mobility; stop just before the pelvis tucks.
- Slamming into lockout — slamming to full extension under a heavy sled loads the joint, not the muscle; stop just short of lockout and keep tension.
- Feet too low — a low foot position pushes the knees far forward and shifts everything onto the quads and knees; move the feet up to bring in the glutes.
- Half reps, too much weight — the leg press invites ego loading, so pick a weight you can take to at least 90 degrees of knee bend with control.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Strength | 4–5 × 3–6 | 2–3 min |
| Muscle growth | 3–4 × 6–12 | 90–120 s |
| Endurance | 2–3 × 12–20 | 60 s |
Use the leg press after squats as a way to get more quad volume without the bracing demand, or as the main lower body lift on a lighter day. Follow each set with calf raises on the same sled to save time.

Frequently asked questions
What muscles does the Smith Machine Leg Press work?
The Smith Machine Leg Press primarily works the glutes. It also involves the quads, hamstrings and calves, which assist the movement and stabilise the joints.
Is the Smith Machine Leg Press good for beginners?
Yes. The Smith Machine Leg Press is rated beginner: it uses a smith machine and the movement is simple to learn. Start light, focus on the full range of motion and add load once every rep looks the same.
What can I do instead of the Smith Machine Leg Press?
If you cannot do the Smith Machine Leg Press, try the Leg Press, the Wide Leg Press or the Curtsy Lunge. Each of them trains the glutes through a similar movement, so you can swap them in without changing the rest of the workout.
How many sets and reps should I do?
It depends on your goal. For the Smith Machine Leg Press, a sensible starting point is strength: 4–5 × 3–6 with 2–3 min rest; muscle growth: 3–4 × 6–12 with 90–120 s rest; endurance: 2–3 × 12–20 with 60 s rest. Put it early in the session while you are fresh, before isolation work for the same muscles.
