7 Best Treadmills for Bad Knees 2024: Picking the Right Machine for You

Suffering from knee pain can be really frustrating, and it’s understandable that you may be wary of cardio because you’re worried about agitating your joints further. However, picking a treadmill that works with your knees versus against them is the key to a mostly painless workout.

In this guide, I’ll tell you my picks for the best treadmills for bad knees and help you select a machine you’ll actually want to use. I’ve also enlisted Amanda Capritto, a certified personal trainer (CPT), for further professional insight on using treadmills for those with knee issues.  

Our team at Garage Gym Reviews has been on dozens of treadmills and even tested some of the best exercise equipment for bad knees. A copious amount of research has gone into examining deck lengths, belt materials, and other useful specs to help determine the best treadmills for bad knees.  We’ve also enlisted members of our expert panel to give more useful information on using treadmills with knee pain.

• Warranty is voided if the treadmill is used/stored in a garage

Bottom Line

If you’re looking to add a workhorse of a treadmill to your home gym, we recommend the NordicTrack Commercial 1750.

I’ll say it: the NordicTrack Commercial 1750 is one of the most complete, all-around best treadmills I’ve tried. For people with bad knees, the re-designed deck of this treadmill now sits lower to help with transitions on and off the 1750. Plus, studies have found that walking backwards downhill can actually help reduce knee pain and this machine has stellar decline capabilities (plus incline options if you’re feeling wild). 

In previous iterations of the 1750 (from 2013-2021), this treadmill had adjustable deck cushioning that was able to be turned on and off. Although the latest 2023 model doesn’t have this feature, I was assured by customer service that the cushioning on the 1750 is the best available. 

If you plan to assemble the 1750 yourself, grab a friend or two to help with the process. This machine is 350 pounds when it arrives at your doorstep, and unless you’re the hulk, trying to unbox and assemble this machine yourself isn’t likely going to happen.

One area where we rated this treadmill a 5 out of 5 is on its technology. If you’re into interactive programming, the updated 1750 features an adjustable 14-inch touchscreen (up from the 10-inch touchscreen of previous years) that is compatible with iFIT memberships. Plus, if you’re taking an iFIT class, you’re able to set your treadmill to automatically adjust to the appropriate speed and incline if you want to focus purely on the treadmill workout at hand.

Best Running Treadmill for Bad Knees: Horizon 7.4 AT

Good for: Someone who wants an intense cardio workout and has the space for a treadmill with a large footprint

Best Running Treadmill

Horizon 7.4 AT Treadmill

GGR Score: 4.2

Product Highlights

• Foldable design
• Deck cushioning
• 12 mph top speed
• Incline up to 15%
• 350 lb use weight capacity
• 22″ W x 60″ L running area
• Built-in workout programs
• Lifetime frame and motor warranty

Pros & Cons

Pros

• Generously sized running deck of 60 inches
• User weight capacity of 350 lbs
• Foldable
• Sturdy and doesn't shake much while in use
• Powerful 3.5 CHP motor

Cons

• Large and not made for compact spaces
• Heavy at 318 lbs
• Lack of touchscreen/interactive programming

Bottom Line

If you're a serious runner and want a foldable treadmill you can trust, I would strongly recommend the Horizon 7.4. Although it doesn't have all the extra technology features (like interactive programming or a touchscreen) it is a well-build machine with a powerful motor.

For someone with knee pain, the thought of running can be chill-inducing. Although a great treadmill can’t make the aches go away, it can make your run a more comfortable experience, which is exactly what the heavy-duty Horizon 7.4 AT does. As the best treadmill for running with bad knees, in our opinion, this machine has “three zoned-cushioning” in the deck, which basically means it is shock-absorbing and will move with you as you do more intense workouts, like HIIT treadmill workouts, interval training, or running. The 22-inch wide by 60-inch long deck is generously sized and allows almost any user to stride with ease. 

I’m also a fan of the Quick-Dial controls, which allow you to change the speed or incline in a flash. This is a nice feature to have, especially if you’re trying to listen to what your body needs at any given time. Although you may or may not use the incline feature, it does go up to 15%, which is more than enough for the average user. 

I would not recommend the Horizon 7.4 for people who have small spaces. The 318-pound treadmill has a large footprint at 76 inches long by 37 inches wide by 63 inches high. Even though this treadmill does have folding capabilities, it’s still a big presence even when it’s tucked away.

If you’re an interactive programming lover, the Horizon 7.4 has Bluetooth connectivity to popular apps like Zwift and Peloton. Although I do wish there was a touchscreen built-in, you can easily use your own iPad or phone to connect with the treadmill and programming.

Best Cushioned Treadmill for Bad Knees: Sole F63

Sole F63 Treadmill

GGR Score: 4.3

Product Highlights

• Folding treadmill
• Costs around $1,200
• Bluetooth speakers, USB port, and cooling fans
• Powerful 3.0 HP motor

Pros & Cons

Pros

• Financing is available
• Bluetooth speakers
• USB port
• Device holder
• 15 different levels of incline
• Cushioned deck
• 20" W x 60" L belt
• 325-lb weight capacity
• Lifetime frame and motor warranty

Cons

• Heavy machine
• No touchscreen

Bottom Line

The Sole F63 Treadmill is an affordable option for people who want a powerful, reliable machine that folds without breaking their budget.

If you’re looking for a cushioned treadmill specifically to help mitigate knee pain while you’re walking or jogging, check out the Sole F63. It has what the company calls a “Cushion Flex Whisper Deck,” which they say reduces joint impact by 40%. While we can’t vouch for that percentage, our testers really enjoy the cushioning system on this machine, saying it provides a pleasant ride. 

The F63 is suitable for a variety of users, too. It offers a 325-pound weight capacity, as well as a 20-inch-by-60-inch deck and a 3.0 CHP motor—all enough for runners and walkers alike. Plus, with a lifetime warranty on both the frame and the motor, you’ll have peace of mind that this machine will last. 

While there isn’t an integrated touchscreen or the ability to connect your device to the machine, the F63 does feature a tablet holder as well as six preset programs to choose from. It also comes with a heart rate monitoring strap—a nice added touch. 

We will say that during testing, the F63 did shake when we cranked up the speed. It doesn’t make the machine feel unstable, but it’s worth noting if you plan to do a lot of high-speed running.

Best Curved Treadmill for Bad Knees: AssaultRunner Pro

Good for: People willing to shell out extra cash for a sturdy, self-powered treadmill

Best Curved

AssaultRunner Pro

GGR Score: 4

Check Price

Product Highlights

• Low-impact shock absorbing belt
• Incredibly sturdy and durable
• Built-in wheels for portability
• 100% athlete-powered

Pros & Cons

Pros

• Extremely popular
• Durable machine
• No motor means fewer maintenance issues
• Easy-to-read monitor
• Thick rubber belt provides great traction
• Bearings under belt provide smooth run
• Sturdy
• Rear handle makes moving easier
• Powder-coating withstands the elements
• Affordable curved treadmill
• Staple for CrossFitters

Cons

• Extremely heavy
• Curved shape takes getting used to
• Plastic shell may crack
• High spin rate on belt
• No fancy monitor, water bottle holder, or other conveniences

Bottom Line

The AssaultRunner Pro is one of the best value non-motorized treadmills for home gyms on the market.

I’m not going to lie—every time I get on one of the best manual treadmills, I pretend I’m a hamster running on a wheel. Weird? Definitely, but hey, whatever keeps me going. If you, too, would like to role play as a hamster, I’m a big fan of the AssaultRunner Pro to fulfill all your rodent dreams. 

This self-powered machine has a shock-absorbing belt and a design that helps people walk or run with better form. This is especially important for people with knee pain, as running with incorrect form can further agitate injuries. 

I also like that the AssaultRunner Pro has a max user capacity of 350 pounds, which makes it an inclusive choice. This also means you can safely do farmer’s carries or other weighted walks like suitcase carries without a problem.

However, all these wonderful features usually mean an expensive price tag, and the AssaultRunner Elite is no exception. This treadmill comes in just under $3,000, and it’s huge. You really need to have a dedicated space in your home or garage gym for this almost 300-pound machine. The Pro comes with a 150,000 mile belt warranty, 5-year frame warranty, and three years for moving parts.

Best Walking Treadmill for Bad Knees: Echelon Stride

Good for: People who need a compact walking treadmill that won’t further agitate bad knees

Best Walking

Echelon Fitness Stride

GGR Score: 4.3

Check Price

Product Highlights

• Folds flat to just 10″
• Lightweight and very portable
• Smaller motor is ideal for walkers
• Bluetooth connectivity to apps

Pros & Cons

Pros

• Auto-fold technology
• When folded, is just 10” deep
• Lightweight and easy to move
• Super simple assembly and usability
• Bluetooth connectivity to Echelon United

Cons

• Weaker motor
• Short running surface at 55”
• Short 1-year warranty
• Basic console

Bottom Line

The Echelon Stride is ideal for walkers and those who jog recreationally, especially people looking for a treadmill that folds flat.

The Echelon Stride is another well-cushioned choice for knee pain sufferers. The deck is made of rubber and absorbs the impact of the user’s steps. I found the deck to be comfortable and supportive. Plus, the 55-inch by 20-inch belt is substantial enough for a slow stroll or a power walk without having to take calculated strides. 

Although this machine has the option to get speeds up to 12 MPH, I wouldn’t recommend consistently counting on this machine to perform at the upper level of its speed range. This is due to the fact that the motor is a subpar 1.75 CHP, which is well below the industry standard for motor performance of 2.5 horsepower. 

However, I do really like the auto-fold feature. This is a machine that actually folds well to a tiny 10 inches, making it easy to store under a bed or in a closet. If you’re tight on space, the Echelon Stride is a solid option to look into. Plus, you don’t have to stress about the machine slamming to the ground and potentially injuring yourself like other foldable treadmills I have tested in the past. 

Another thing I love? The Stride comes almost entirely pre-assembled. Once you unbox the machine, simply unfold the handrails and plug it in to a compatible outlet and voilá! You’re ready to get started.

Best Treadmill for Bad Knees with Interactive Programming: Bowflex Treadmill 10

Good for: People who love programming but also want one of the best home treadmills for bad knees

Best Interactive Programming

Bowflex Treadmill 10

GGR Score: 3.7

Check Price

Product Highlights

•  -5% decline to 15% incline
• Speeds up to 12 MPH
• Compatible with JRNY, Bowflex’s online fitness platform
• 10″ interactive console
• Cushioned running deck
• Soft-drop folding system

Pros & Cons

Pros

• 1-year JRNY subscription included with curated playlists and training content
• 22” x 60” running deck
• Convenient speed and incline knobs
• Max user weight of 400 pounds
• Decline capabilities
• Interactive screen
• Heart rate armband included
• Ability to stream Netflix, Hulu, Amazon Prime Video and HBO Max with subscription

Cons

• At their own admission, Bowflex states it does not disclose information on motor power
• Heavy
• Some users found the screen to be too small
• Some connectivity issues reported

Bottom Line

The Bowflex Treadmill 10 has a lot to offer users when it comes to technology and performance. It comes with a roomy, cushioned running surface, an interactive touchscreen display and it is heavy-duty. Keep in mind that Bowflex does not disclose their horsepower for the motor but users rave over the powerful feel.

The Bowflex Treadmill 10 is the cardio machine equivalent to a Buick. This mammoth features a generous 22-inch by 60-inch running path and “comfort tech deck cushioning.” I found the Treadmill 10 to be very comfortable to use and the deck has shock absorption that makes jogging or walking feel less stressful on joints, particularly the knees. 

One of my favorite parts of the Treadmill 10 is the included touchscreen, which connects with JRNY programming. JRNY is similar to iFIT, but just less fleshed out. However, at just $19.99 per month, it is one of the cheaper programming options I’m aware of. You’re able to take a variety of classes that aren’t just limited to the treadmill including strength, yoga, and pilates options. 

The 323-pound machine is extremely stable, and I had no issues with the machine shaking while in use. The Treadmill 10 also has a max user capacity of 400 pounds, which is well above the industry standard of 300 pounds. Since this heavy machine has a large footprint, it makes the most sense to have a permanent or semi-permanent home for the Treadmill 10. Plus, you’ll probably want to pay for expert assembly from Amazon or the like after you purchase this machine, since it is a beast.

Although the T10 is actually able to be folded, it’s not really a spacesaver: The protruding screen doesn’t allow for a seamless or flat fold, which limits your storage options. Plus, the attached wheels to move the treadmill are small and not conducive to rolling the machine across carpet.

Best Budget Treadmill for Bad Knees: UREVO Under Desk Treadmill

Good for: A casual exerciser who wants an inexpensive cardio machine with a cushioned belt

Best Budget Treadmill for Bad Knees

UREVO 2-in-1 Under Desk Treadmill

GGR Score: 3.6

Check Price

Product Highlights

• Folds flat to fit under beds and couches
• Comes ready to go; no assembly required
• Easy to move
• Can also be used under a standing desk
• No incline

Pros & Cons

Pros

• Under $400
• Handle can be folded under to use under a desk
• Easy to store and good for people in tight spaces

Cons

• Short and skinny deck not ideal for running
• User weight capacity below industry standard at 265 lbs
• Max speed of 7.6 mph

Bottom Line

If you are looking for a foldable treadmill for under $500, the UREVO 2 in 1 is a great option for you.

Listen, the UREVO 2-in-1 Under Desk Treadmill is not a Peloton Tread. It doesn’t have all the fun technology features or extra long deck. However, this is one of the best folding treadmills and is under $400. It has five layers of non-slip rubber on the running belt. I am a very clumsy individual, so non-slip anything is always a good option for me. Even if you’re not fall-prone, if you have less than ideal knees, this is a nice safety option to have. 

RELATED: Treadmill Safety

I wouldn’t recommend the machine for running or jogging, purely because the deck isn’t long enough at 16.5 inches by 42.5 inches. This is a common compromise on machines that are budget-friendly, but it can still be used just fine for walking. Plus, at under 80 pounds, the UREVO can be easily moved from room to room without a lot of fuss. I found it easy to fold—the handlebars come down toward the belt—and move with the attached wheels. 

RELATED: How to Move a Treadmill

Since the actual shell of the UREVO is constructed using a lot of plastic, I don’t know how long this machine will last. The controls on the top part of the deck seem cheap and the remote that controls the speed is small. I’d recommend taping it to the treadmill so you don’t lose it, otherwise you won’t be able to adjust the speed at all. But, if you’re looking for the best budget treadmill for bad knees, the UREVO 2-in-1 might be a good option.

Take a look at our full UREVO Treadmill review.

Other Treadmills We Researched

These machines didn’t quite make the list, but we still think they’re worth mentioning. Check out our thoughts on these four high-quality treadmills:

Nautilus T618 Treadmill: This treadmill was recalled on June 9, 2023, for issues with the machine self-starting and requires a software update from the company to be safe to use. But, beyond that, the T618 features a sturdy 3-ply belt and generously sized deck. At $1,500, we do wish it had an included touchscreen to view programming instead of the backlit LCD screens, but the Bluetooth connectivity is a nice add. (Full Nautilus T618 Treadmill review here.)

Schwinn 810 Treadmill: This treadmill has “SoftTrak Cushioning” for a comfortable workout and is under $1,000. However, I’m not crazy about the 275-pound max user capacity, as the industry standard is 300 pounds. 

ProForm Carbon T7 Treadmill: For under $1,000, this cardio machine is a good option for people with bad knees due to its ISO Flex belt cushioning. (Full Proform Carbon T7 treadmill review here.)

How We Picked and Tested

Every single treadmill that made this list has been personally tested by a member of our team. When testing these machines, we paid special attention to the cushioning and how it felt to run or walk for any length of time. 

We also considered things like deck length, and any adjustments or features that made exercising a bit easier. After all, if you’re struggling with knee pain, the last thing you want is a complicated and frustrating workout experience

Benefits of Treadmills for Bad Knees

Surprise surprise, treadmills can actually be a good choice for someone with bad knees. I know, shocker. Here are some reasons you might want to add a treadmill to your home gym, even if you suffer from joint pain:

Reduce Risk of Further Injury

Consistently walking on a treadmill if you have knee pain can actually benefit you in the long run. Studies have shown that frequently using a treadmill for exercise can strengthen the muscles surrounding your knee, therefore reducing your risk of further injuring your knee. Plus, physical activity increases blood flow overall, which can help promote healing from an injury.

“Despite the common belief that walking and running are bad for the knees, both types of exercise can actually improve joint health by increasing bone density and strengthening the muscles around the joint itself,” says CPT Amanda Capritto. 

RELATED: Treadmill Benefits

More Comfortable Workout

Extra deck cushioning on your treadmill means a more pleasant workout for you (and your knees). It’s a lot easier to focus on the task at hand if you aren’t thinking about how horribly your knees hurt during your workout sessions. 

Improve Balance

As we get older or have injuries, it is even more important to continuously exercise to improve your balance to avoid falling. According to a clinical trial, consistent treadmill training is effective for improving balance control. Even more of a reason to add a treadmill to your home gym!

What to Look for in Treadmills for Bad Knees

If you suffer from occasional or chronic knee pain, the last thing you want is a treadmill that will aggravate your joints even more. Never fear! We’re here to help you make the right decision by equipping you with useful information you need to know. Let’s get started:

Cushioning

The No. 1 thing you should look for when purchasing a new treadmill (if you have knee pain) is heavy cushioning on the running deck. Pay close attention to the information about the machine’s belt. Is it 2-3 ply? Is the PVC belt at least .8mm thick? Is there any information about additional cushioning considerations the brand has made when designing the deck? These are all things to consider before hastily choosing a treadmill. 

Incline and Decline

Depending on if you plan to use incline or decline, this may not be much of a concern for you. I don’t personally suffer from knee pain, but I do have issues with my reconstructed ankle and I do not enjoy using high inclines because it hurts. If this is similar to you with your knees, you may be able to get a cheaper treadmill that doesn’t have incline and decline training options. 

However, studies have shown that regularly walking backwards downhill can actually help strengthen knees. If you’re feeling up to it, give it a try.

Soft Drop Feature

If you have bad knees, you likely don’t want to struggle to fold and unfold your new treadmill and risk hurting yourself further. If this is the case, make sure the machine you chose has some sort of soft drop feature or hydraulics that allow the deck to slowly come down on its own. 

Trust me, I don’t even have bad knees and it is a struggle when you’re unfolding a heavy treadmill that doesn’t have a gas shock. You end up having to squat with the machine as it comes down to avoid it slamming on the floor and potentially straining your knees.  

Deck Size

Whether you enjoy walking or running, you’ll likely want a sizable deck for your new treadmill. The industry standard on a deck for running is 22 inches by 60 inches, but most budget treadmill options are quite a bit smaller. Hey, they have to cut costs somewhere. 

However, if you’re someone with knee problems, the more walking or running space you have, the better. I feel like you shouldn’t have to think too hard about the steps or stride length you’re taking, so the larger the deck for those with knee problems, the better. 

Control Panel

Personally, I always want all of the controls to be easy to use and intuitive for any user that steps on the treadmill. Who wants to constantly be fumbling around to figure out how to increase their speed or change the preset workout program? Certainly not me. Especially if you have an injury, like bad knees, making your experience on a treadmill as streamlined as possible is key.

Tips for Using a Treadmill with Bad Knees

Although I can’t magically make your knees hurt less (I’m sorry, I wish I could), I can give you some helpful reminders and tips for using a treadmill if you have bad knees:

• Warm up ahead of time: Spend 10-15 minutes rolling out tender spots, stretching properly, and getting your body (and knees) primed to hit the treadmill.
• Wear the right shoes: You won’t be doing yourself any favors if you wear unsupportive running shoes on the treadmill. Look for options that fit your foot properly, allow you to adjust the laces if necessary, and have cushioning.
• Avoid super high inclines: Although moderate incline should generally be okay for someone with bad knees, you’ll likely want to avoid the 10-15% incline range. The higher the incline, the more your knees will be forced into unnatural angles. 
• Walk backwards: One of the best treadmill workouts for bad knees is walking backwards. Studies have shown that walking backwards can be beneficial for people with knee pain because it can improve “balance and stability.” 
• Listen to your body: You are the only one that truly knows how your body is feeling at any given moment. Do your best to listen to the signs it gives you to figure out when it’s had enough for the day.
