Alternatives to Lunges: 6 Knee-Friendly Exercises for Stronger Legs

YLunges are a fantastic lower-body exercise, but they’re not for everyone. The forward step and single-leg landing can aggravate sensitive knees, they demand good balance, and some people simply want variety. Fortunately, you can train your legs just as effectively, and often more comfortably, with the right alternatives.

The trick is choosing substitutes that genuinely replicate what makes the lunge valuable, rather than just any leg exercise. Here’s how to judge a good alternative, followed by six of the best.

This article is informational and not a substitute for individual medical or training advice. If you have knee pain or an injury, consult a professional before starting new exercises.

What Makes a Good Lunge Alternative?

Not every leg exercise is a true lunge substitute. A barbell squat, for instance, trains the legs but works very differently. To genuinely replace the lunge, an exercise should tick most of these boxes:

• It’s unilateral. The lunge trains one leg at a time, which builds balance, corrects strength imbalances between your legs, and has excellent carryover to real life and sport. The best alternatives keep this single-leg element.
• It involves dynamic knee flexion and extension. The lunge takes the knee through a full bend and straighten under load. A static hold like a wall sit doesn’t replicate this, so a good alternative should be dynamic.
• It activates the glutes. This matters more than people realise. Glute activation is what stabilises the knee, which is why a leg extension (all quad, no glute) isn’t a great lunge substitute despite involving the knee.
• It’s easy to progress and regress. You should be able to make it harder or easier to suit your level.

The exercises below satisfy these criteria while placing less strain on the knees, making them ideal if the lunge bothers you.

The 6 Best Alternatives to Lunges

Okay, so, if you are now ready to start training your legs and you want to get the benefits of lunges, without any of the risks or drawbacks with regards to the knees, here are several awesome alternatives.

1. Bulgarian Split Squats

The gold-standard lunge alternative, and arguably a superior exercise in its own right. By elevating your rear foot on a bench, you place almost all the load on the front leg while removing the forward step, which means no travelling and far less balance instability than a walking lunge. That stability is exactly why it’s so valuable: with your position fixed, you can load it heavily and really overload the front leg. The elevated rear foot also increases the range of motion at the front hip, giving the glute and quad a deep, growth-promoting stretch at the bottom. It’s unilateral, dynamic, and intensely glute-activating, ticking every box.

How to perform it:

1. Stand a couple of feet in front of a bench and place the top of one foot behind you on it.
2. With most of your weight on your front foot, lower straight down by bending your front knee and hip.
3. Descend until your front thigh is roughly parallel to the floor, keeping your torso tall.
4. Drive up through your front heel to the start, complete your reps, then switch legs.

Coaching cue: to spare the knee, keep your front shin fairly vertical and lean your torso forward slightly, this shifts more load to the glute and less to the knee.

2. Step Ups

One of the most knee-friendly options, and mechanically very close to a lunge. The crucial difference is direction: by stepping upward rather than forward, you eliminate the impact and forward knee translation that stresses the joint in a lunge, while still training the leg unilaterally through a full range of motion. It’s also highly functional, mirroring the everyday action of climbing stairs, and easily scaled by changing the box height or adding weight.

How to perform it:

1. Stand facing a sturdy box or bench at around knee height.
2. Place one whole foot flat on the box.
3. Drive through that front heel to stand up fully on the box, bringing the trailing leg up.
4. Step back down under control with the same leg leading, and repeat before switching sides.

Coaching cue: push through the heel of the elevated leg and avoid pushing off the floor with the bottom foot, that’s what makes the working leg do the job. A higher box shifts more emphasis to the glutes and hamstrings.

3. Static Split Squats:

Think of this as a lunge with the step and travel removed. You set up in a split stance and simply move straight up and down, which strips out the balance, stepping, and deceleration demands that make lunges hard on the knees, while keeping the exact same unilateral, glute-and-quad-building benefit. Because you’re not moving your feet between reps, it’s easier to learn and much easier to load safely, making it a brilliant stepping stone for anyone building toward full lunges or working around discomfort.

How to perform it:

1. Step one foot forward into a split stance, feet about hip-width apart for stability.
2. Keeping your torso upright, lower straight down by bending both knees.
3. Stop when your back knee is an inch or so off the floor, with your front shin near vertical.
4. Press up through your front heel without moving your feet, and repeat before switching sides.

Coaching cue: keep roughly 90 percent of your weight on the front leg. The back leg is mainly for balance.

4. Reverse Lunge

If it’s specifically the forward lunge that bothers your knees, simply reversing the direction can solve the problem. Stepping backward rather than forward dramatically reduces the forward travel of the knee and the impact of the landing, taking pressure off the joint. It also shifts the emphasis slightly toward the glutes and hamstrings, making it both more knee-friendly and more posterior-chain focused, while preserving the unilateral, dynamic pattern that makes lunges worthwhile.

How to perform it:

1. Stand tall with your feet together, holding dumbbells at your sides if you wish.
2. Take a controlled step backward with one leg.
3. Lower until your back knee nearly touches the floor and your front thigh is parallel.
4. Drive through your front heel to return to standing, and alternate or complete reps on one side.

Coaching cue: control the step back rather than dropping into it, and keep your weight in the front heel to protect the knee.

5. Single-Leg Leg Press

When knee or hip issues rule out standing single-leg work, or you simply want to load heavy without any balance demand, the single-leg leg press is outstanding. The machine supports your back and controls the movement path entirely, so there’s no stability challenge and you can regulate the depth precisely to stay within a pain-free range, while still training each leg individually and hard. It builds the quads, glutes, and hamstrings and even improves knee stability.

How to perform it:

1. Sit in the leg press machine and place just one foot flat and centred on the platform, keeping the other clear.
2. Select a lighter weight than you’d use with both legs, then release the safety catches.
3. Lower the platform under control until your knee reaches a comfortable, pain-free depth.
4. Press back up through your heel without locking the knee, complete your reps, then switch legs.

Coaching cue: adjusting your foot position changes the emphasis, as we cover in our guide on foot placement for the leg press.

6. Goblet Squat

The one bilateral option here, included because it’s such an accessible, knee-friendly way to train the whole lower body when you’d rather avoid single-leg work entirely. Holding a weight at your chest acts as a counterbalance, letting you sit back and keep your torso upright, which reduces stress on the knees and lets you comfortably reach a good depth. It’s not unilateral, so it doesn’t address imbalances the way the others do, but it’s a superb, joint-friendly leg builder and a great choice for beginners.

How to perform it:

1. Hold a single dumbbell or kettlebell vertically against your chest with both hands.
2. Stand with your feet a little wider than shoulder-width, toes turned slightly out.
3. Push your hips back and bend your knees to squat down, keeping your chest up and heels planted.
4. Descend as far as is comfortable, then drive up through your heels to stand.

Coaching cue: let your elbows track down between your knees at the bottom, and sit back rather than letting the knees drift far forward. It builds on the same pattern as the barbell squat.

Which Should You Choose?

• For sensitive knees: step-ups, reverse lunges, and the single-leg leg press are gentlest.
• For heavy loading and muscle: Bulgarian split squats and the single-leg leg press.
• For learning or building up: the static split squat.
• For no balance demand at all: the goblet squat or single-leg leg press.
• For glute development: step-ups (high box), reverse lunges, and Bulgarian split squats, all of which also feature in our guide on how to get a bigger butt.

You don’t need all six. Pick one or two that suit your knees and equipment, and rotate them over time.

How to Program Them

Treat these as you would lunges. For the unilateral exercises, work in a rep range of around 8 to 15 per leg for two to four sets, always completing both sides. Prioritise good form and a full, pain-free range of motion over heavy weight, then apply progressive overload, adding reps or load gradually as you get stronger. Training legs two to three times a week works well for most people; see our guide on how many exercises per muscle group to structure your volume.

Frequently Asked Questions

What is the best alternative to lunges? The Bulgarian split squat is the best overall, offering the same unilateral, glute-and-quad-building benefits as a lunge with more stability and easier loading. For sensitive knees specifically, step-ups and reverse lunges are excellent gentler options.

What can I do instead of lunges for bad knees? Step-ups, reverse lunges, and the single-leg leg press are the most knee-friendly, as they reduce the forward knee stress and impact of a standard lunge. Start light, keep within a pain-free range, and stop if you feel pain.

Can you build legs without lunges? Absolutely. Bulgarian split squats, step-ups, split squats, leg presses, and goblet squats all build strong, muscular legs. The lunge is effective but far from essential for lower-body development.

Are split squats better than lunges? For many people, yes. Split squats and Bulgarian split squats offer the same unilateral benefits with more stability, allowing you to load heavier and stress the knees less, since there’s no stepping or balancing. They’re a superb substitute.

Do lunge alternatives work the glutes? Yes. Good lunge alternatives like step-ups, reverse lunges, and Bulgarian split squats strongly activate the glutes, which is part of what makes them effective and also helps stabilise the knee during the movement.

The Bottom Line

You don’t need lunges to build strong, capable legs. Whether you’re working around sore knees, poor balance, or simply want variety, alternatives like the Bulgarian split squat, step-up, and reverse lunge deliver the same unilateral, glute-activating benefits, often with far less strain on your joints.

Use the framework above to judge any exercise for yourself: is it unilateral, dynamic, and glute-activating, and can you progress it? Choose a couple that fit your body and equipment, perform them with good form through a pain-free range, and load them progressively over time. Do that, and your legs will keep getting stronger, no lunges required. lunges and just as effective, any of the above will make a worthy addition to your leg workouts.
