The seated leg press does work your glutes, but not as its primary target. Your quadriceps do the heavy lifting during a standard leg press, with glute activation measured at roughly 15-22% of maximum voluntary contraction in typical setups. That’s enough to contribute to glute development over time, but far less than the quadriceps engagement, which can exceed 200% of baseline activation at moderate loads. The good news: a few simple adjustments to foot placement and depth can significantly shift the balance toward your glutes.
How Much Glute Work the Leg Press Actually Provides
The leg press is fundamentally a quad-dominant exercise. A systematic review in the International Journal of Environmental Research and Public Health confirmed that the vastus medialis and vastus lateralis (the two largest quad muscles) show the greatest activation during the movement, with the rectus femoris close behind. Glute activation during a standard foot position sits around 15-22% of maximum effort, depending on stance width.
That changes meaningfully when you modify the setup. In one study using a high foot position on an inclined leg press at 80% of one-rep max, gluteus maximus activation jumped to approximately 115% of resting baseline, which was actually the highest muscle reading in the entire lower body for that variation. So the leg press can be a legitimate glute exercise, but only when you deliberately set it up that way.
Foot Placement Makes the Biggest Difference
Where you put your feet on the platform is the single most important variable for shifting work to your glutes. Two changes matter most:
- Place your feet higher on the platform. This increases how much your hips flex and extend throughout the rep, which is the primary movement pattern your glutes are built for. A higher foot position also reduces quad involvement, letting the glutes and hamstrings pick up a larger share of the load.
- Use a wider stance with toes slightly turned out. This brings in hip abduction, which recruits the gluteus medius and minimus (the upper and outer portions of your glutes). A wide, high position is the combination most commonly recommended for glute-focused leg pressing.
For comparison, a low foot placement with a narrow stance keeps most of the work in your quads. If your goal is glute development, that’s the setup to avoid.
Depth and Range of Motion
Going deeper into the leg press increases the stretch on your glutes at the bottom of the movement, and a stretched muscle under load is one of the strongest signals for growth. The deeper you allow your knees to travel toward your chest, the more hip flexion you create, and the harder your glutes have to work to reverse the movement.
Full-range reps give your glutes both a deeper stretch at the bottom and a stronger contraction at the top. Cutting reps short, where the sled barely moves, keeps most of the tension in your quads and knees. If you’re using the leg press specifically for glute work, prioritize controlled depth over heavy weight.
There’s an important limit, though. If you lower the sled so far that your pelvis tucks underneath you (sometimes called “butt wink”), you shift stress onto your lower back. This posterior pelvic tilt places significant load on the lumbar discs and ligaments and can cause sacroiliac joint pain. To avoid it, adjust the seat so your knees start at least at a 90-degree angle with your back flat against the pad. Drive through your heels, keep your core braced, and stop the rep before your lower back lifts off the seat.
Does It Actually Build Glute Size?
The leg press can contribute to glute hypertrophy, though the evidence is mixed on how well it works as a standalone exercise. One study found that eight weeks of leg press training increased gluteus maximus size by 13-18%. Another nine-week study using the 45-degree leg press found increases of 25-30%, but with so much variation between subjects that the results weren’t statistically significant.
The strongest evidence comes from programs that include the leg press alongside other exercises. A 24-week study comparing multi-joint routines (which included the leg press, squat, deadlift, and lunge) to single-joint routines found that the multi-joint group increased glute thickness by about 14.5%, roughly five times more than the single-joint group. A 10-week study combining the 45-degree leg press with stiff-leg deadlifts produced about 6% glute growth, which jumped to 9.3% when a barbell hip thrust was added.
The takeaway: the leg press contributes to glute growth, but it works best as one piece of a program rather than your only glute exercise. Pairing it with a hip-dominant movement like a hip thrust or deadlift variation covers the full range of glute function that the leg press alone doesn’t fully address.
The 45-Degree Sled vs. the Seated Machine
Not all leg presses are the same. The two most common types are the seated horizontal machine (where you push the platform straight out in front of you) and the 45-degree incline sled (where you push the weight up along an angled track). Both work the quads, hamstrings, and glutes, but the 45-degree version places more emphasis on the glutes because it allows a greater range of hip flexion through the movement. If your gym has both, the 45-degree sled is the better choice for glute-focused work.
On a seated horizontal machine, you can still bias the glutes with high, wide foot placement and controlled depth. You’ll just get slightly less glute involvement compared to the angled version at the same load and range of motion.
How to Set Up the Leg Press for Glutes
Putting it all together, here’s what a glute-focused leg press setup looks like: place your feet high on the platform, roughly shoulder-width apart or slightly wider, with your toes pointed out about 15-30 degrees. Lower the sled slowly until your knees are well past 90 degrees, but stop before your lower back rounds off the pad. Drive through your heels on the way up and consciously squeeze your glutes at the top of each rep. Use a weight that lets you control the full range of motion rather than loading the sled so heavy you can only manage partial reps.
A mind-muscle connection matters here more than on most exercises. Because the quads naturally dominate the leg press, actively focusing on your glutes during each rep can increase their recruitment. This isn’t just gym folklore: mental focus on a target muscle has been shown to shift activation patterns during resistance training, particularly at moderate loads.
