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.  

Why You Should Trust Us

The 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. 

6 Best Treadmills for Bad Knees

Overall Best Treadmill for Bad Knees: NordicTrack Commercial 1750

Good for: People who want a reliable treadmill with both excellent cushioning and all the bells and whistles. 

My Favorite Things:

  • Comfortable deck cushioning 
  • Included 14” touchscreen on the new model
  • Compatible with iFIT programming
  • Decline and incline settings
  • Financing options available through the NordicTrack website

My Callouts:

  • Time consuming to assemble 
  • Close to 350 lbs boxed
  • Expensive at close to $2,000

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 2022 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.

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 Curved Treadmill for Bad Knees: AssaultRunner Elite

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

My Favorite Things:

  • Treadmill belt is shock-absorbing
  • Sloped design helps users run/walk with better form
  • Can support up to 400 lbs
  • Lifetime warranty on the belt

My Callouts:

  • Around $4,000 
  • Super heavy and difficult to move
  • Very basic monitor

I’m not going to lie—every time I get on a manual treadmill, 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 Elite to fulfill all your rodent dreams. 

Coop running on the AssaultRunner Elite treadmill

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 Elite has a max user capacity of 400 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 $4,000, and it’s huge. You really need to have a dedicated space in your home or garage gym for this almost 375-pound machine (when boxed). On the bright side, the Elite comes with a lifetime belt warranty, 10-year frame warranty, and a three-year part warranty. With such a comprehensive warranty, it makes the price tag a little easier to swallow.

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.

My Favorite Things:

  • Under $400 
  • 5 layers of cushioning on the deck
  • Space-saving; easy to store and move
  • Lightweight

My Callouts:

  • No incline options 
  • Short deck at 16.5” x 42.5”
  • Bare bones with no technology extras

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 compact treadmill is under $400 and 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

putting handlebar down on urevo treadmill

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.

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.

My Favorite Things:

  • Cushioned, shock-absorbing deck 
  • Generously sized running area at 22″ x 60″
  • Can sync with popular fitness apps such as Peloton and Zwift 
  • User-friendly incline and speed controls with a dial

My Callouts:

  • Large footprint; not ideal for small spaces 
  • Bring your own device to stream programming
  • 318 lbs and difficult to move

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. 

RELATED: Best Folding Treadmill

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 Walking Treadmill for Bad Knees: Echelon Stride

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

My Favorite Things:

  • Deck is made of rubber and is “impact-absorbing” 
  • Auto-fold feature makes storage a breeze
  • Under $1,500
  • Maximum speed options up to 12 MPH

My Callouts:

  • Weak 1.75 CHP motor (2.5 HP motor is the industry standard) 
  • No touchscreen
  • Subpar warranty
  • No incline availability

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. 

echelon stride treadmill product photo

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.

My Favorite Things:

  • Plenty of deck cushioning 
  • Compatible with JRNY programming 
  • 400 lbs max user weight capacity
  • Decline and incline levels

My Callouts:

  • Large machine at 323 lbs
  • Although it is foldable, it doesn’t fold very flat
  • Hard to assemble by yourself

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.

RELATED: How to fix a treadmill

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.

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, 2022, 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. 

Sole F63: If you don’t mind a more primitive but large LCD display, you may enjoy the F63, as it has pretty solid belt cushioning. The Sole website even claims the “Cushion Flex Whisper Deck” can reduce impact by up to 40% on joints. I can’t verify that in any way, but the belt does feel more cushioned than the average treadmill. 

RELATED: Sole F63 Treadmill Review

LifePro Pacer: Although I’m a fan of the Pacer’s folding capacities, I don’t feel that the deck is particularly cushioned. It isn’t a bad machine by any means, but I don’t think it is an ideal choice for someone who suffers from knee pain. 

RELATED: Lifepro Pacer Folding Treadmill review

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:

tread bowflex treadmill 10

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!

Buying Guide: 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. 

FAQs about Treadmills for Bad Knees

Are treadmills good to use if you have bad knees?

According to a study, “treadmill walking exercises have positive effects on balance ability and skeletal muscle strength.” However, you and your doctor know your individual body best. Please consult with a licensed medical professional before starting any new exercise programs with a knee injury present.

What are some low-impact exercises I can do if I have bad knees?

Well well well, I’m glad you asked. We’ve actually compiled a whole article full of low-impact exercise ideas for post-injury training. Whether you like using ellipticals, are looking to get a stronger cardiovascular system, or are on a weight-loss journey, low-impact exercises are for you!

How can I run on a treadmill without hurting my knees?

I can’t provide any magical advice that will suddenly make running on a treadmill feel like floating on Willy Wonka’s chocolate lake if it usually feels like a near-death experience. However, I can suggest things like warming up properly, using a treadmill with a well-cushioned deck, and stopping when your body tells you it’s had enough. 

RELATED: Best Home Treadmill for Running

What are some treadmill features to look for when purchasing?

Look for things like a generously sized running surface, cushioning system, preset workout programs, water bottle holders, powerful motor, heart rate monitoring, tablet holders, transportation wheels, cooling fans, and an HD touchscreen. Obviously depending on your budget, you don’t need to have all of these things in order to get a treadmill that will help you meet your fitness goals, but they are things to consider. 

Check out our full treadmill buying guide for the best tips.

How can I feel less knee pain while walking or running on the treadmill?

“This will vary from person to person, but a good place to start is checking your shoes. By looking at the tread on the bottom of your shoes, you can tell how your gait (walking pattern) might be affecting your knees. For example, a shoe that is unusually worn down on the outer edge of the outsole indicates that the person is overpronating their feet, AKA turning their arches upward. This adds undue stress on the knees and can be corrected with a variety of leg and ankle exercises over time. A short-term solution is to experiment with your stride length and see if you can achieve a heel-to-toe pattern that limits pain,” explains CPT Amanda Capritto.
