Unlock Legendary Leg Power: The Secret Leg Press Technique That Bodybuilders Swear By—Are You Doing It Wrong?

Ever wondered which exercise lets you fling around the heaviest weights without turning into a human pretzel? It’s a big deal when you’re plotting out your workout, right—because piling on the pounds safely equals bigger muscles and insane strength gains. Sure, the deadlift or back squat might pop into your head first—they’re the rockstars of heavy lifting. But hold up! Before you swear off machines forever, meet the leg press: the unsung heavyweight champ quietly waiting in the corner of the gym. This beast lets you stack plates like there’s no tomorrow, all while keeping your spine off the hook. Sounds like a win-win, but don’t be fooled—it’s not just plop down and push; mastering the leg press means learning how your body ticks to avoid injuries and squeeze out max power. Intrigued? Let’s dive into why fitness guru Ebenezer Samuel calls this your “most powerful exercise” and how you can make the leg press your secret weapon in the quest for leg day domination. LEARN MORE

WHICH EXERCISE ALLOWS you to work with the most possible weight? That’s important to think about when you’re building a workout plan, since you’ll be able to build strength and muscle working with heavy loads.

The deadlift or back squat might be the first options that come to mind, and these big barbell movements are solid answers. But expand your horizons to include machine-based movements, and there’s an easy answer to this question: the leg press machine.

The leg press offers exercisers an enticing proposition: Load as much weight onto the rig as you can handle, plop down into the seat, and push away. You’re not working with free weights, so in theory there’s much less to worry about when it comes to form. But in reality, you’ll need to understand a bit more about the exercise—and the way your body works—to perform it as safely and effectively as possible.

Here, Men’s Health fitness director Ebenezer Samuel, C.S.C.S., explains everything you need to know about what the leg press, which he calls “your most powerful exercise.”

How to Do the Leg Press

Men’s Health

The biggest mistake you can make when you do the leg press, according to Samuel, is not approaching the machine seriously. You can’t just sit down in the rig and expect to perform well without dialing in your form. Think about the leg press as a squat from a different position to begin, then focus on your positioning—both upper and lower body—to solidify your approach.

Upper Body Positioning

Even if your spine isn’t under load, you need to maintain upper body and core tension. Keep your torso engaged throughout the movement—this will help to avoid any lower back stress.

Grab the handles on the machine and pull yourself down into the seat.
Squeeze your glutes to drive your butt down into the seat while engaging your abs to drive your lower back into the pad.
Squeeze your shoulder blades and drive your neck into the pad, too.

Leg Position

Where you place your feet on the rig will depend on your desired stimulus and anatomical needs.

Place your feet on the sled. Aim for a position where your knees are at least hip-width apart to start (although Samuel says you can go wider as well).
The closer you place your feet to the back of the plate (in near your body), the more knee-dominant the movement will be, making it more quad-focused. If you place you feet further away, the movement will be more hinge-dominant, meaning it will be more focused on your hamstrings and glutes.
If you’re just starting out, place your feet generally in the middle.
The leg press allows you to keep your toes pointed forward, which might not be an option when you’re squatting under a bar due to hip mobility constraints.

How to Perform Leg Press Reps

Press through the sled with your feet, maintaining tension in your torso. Release the sled from the safety lock, then control the weight down.
Watch your knees as you lower the weight, making sure you don’t allow them to cave in or track excessively outward.
Lower down as far as you can, maintaining upper body tension with your back flush against the pad. Don’t allow your butt to raise off the seat; if you shift you’ve gone too deep.
Press through the pad with both feet to raise the wait back up, extending your knees.
As you fatigue, Samuel notes that you can perform reps within a shorter range of motion.

Benefits of the Leg Press

Work with big weights
Less stress to CNS
Develop leg muscle and strength
Good for beginners

As stated earlier, the leg press allows you to train your legs with heavy loads. You’ll be able to work with bigger numbers than your free weight movements (meaning: exercises that use implements like dumbbells, barbells, and kettlebells) for one simple reason: You’re not stressing your spine.

“We’re removing something called axial loading,” explains Samuel. “When I’m doing a squat or a deadlift, I’ve got all that pressure from the weight and from gravity coming down on my spine.”

Since your position within the machine doesn’t force you to support the weight with your spine, you’ll be able to pile on more plates and use only your big leg muscles. What’s more, you’ll avoid straining your central nervous system (CNS), which causes fatigue and might limit your ability to keep pumping out reps sooner.

This position also makes the leg press a simple tool for beginners. You’ll be able to work with heavier weights more quickly than the form-intensive free weight exercises. That said, you shouldn’t totally skip those moves (squats, deadlifts, lunges) in favor of the leg press; instead, use the machine as a tool to build strength to make your free weight exercises stronger.

Which Muscles the Leg Press Trains

Quads
Hamstrings
Glutes

The leg press is all about your legs (duh), so all the big muscles in your lower body are involved. That means the quads, hamstrings, and glutes. You’ll also work the smaller supporting muscles in your legs—not to the same degree as in free weight exercises, to be clear—but the big ones will be the focus.

Who Should Do the Leg Press

Bodybuilders
Strength training athletes
Beginners

Since the leg press really allows you to home in on the legs and work with heavy loads without focusing on the specific form or function of free weight movements, it’s a great option for bodybuilders or anyone else whose main gain is to grow their muscles.

That said, Samuel says that more functionally-minded strength training athletes can use the leg press to overload their quads, glutes, and hamstrings, which will benefit their other lifts and overall strength performance in the long run. As noted above, beginners will also benefit from the lack of axial loading as they build strength for free weight movements. Anyone can use the exercise; ultimately, your goals will dictate how often you include it in your training.

How to Fit the Leg Press in Your Workout

One of the best ways to use the leg press, according to Samuel, is to push high reps and volume. Consider a set-rep structure with three sets to four sets of 15 to 20 reps. You can also do fewer reps with more weight to really push your leg development. Just don’t try to max out the leg press, no matter what Ronnie Coleman did.

Slot in the leg press as the third or fourth movement in a lower body workout, especially after you’ve built up CNS fatigue with the big time exercises like squats or lunges with free weights. Think of it as your “endgame exercise or finisher” after you’ve done the other work when you want to level up your leg day.
