The Ultimate Guide To Treadmills For Bad Knees and How They Work

You want to get back on track – but you feel like your bad knees are holding you back?

You’re not alone. Knee arthritis is a deterioration in the joint cartilage. It’s a common disability for many people, and it can prevent them from fulfilling everyday activities – such as climbing stairs or even walking.

People need exercise – and most of us rely on readily available fitness apps to meet our goals. But for someone living with bad knees and joint pain, the choice of proper equipment – a treadmill for bad knees, for example – becomes crucial.

The right treadmill – one that has a running deck with a cushioning system – can make a difference. So, before making that choice, you should inquire about other specifications, too, such as weight capacity, speed range, incline, preset workout programs, and so on.

You should learn how these machines work, too.

On that note, if you’re looking for the best treadmill for bad knees – you just need to stay tuned.

Using A Treadmill If You Have Knee Joint Pain

Yes, working out with bad knees is allowed.

As long as you follow the advice of your doctor or therapist and don’t overdo it with your daily exercise routine, using indoor treadmills could do wonders for your health and speed up your recovery.

With things like this, it’s very important to keep in mind that there are several different models of treadmills – and not every type is suitable for people dealing with knee pain.

Plus, not all of them work the same.

It’s easy to get injured – especially if you already have joint pain.

So, before you actually set foot on your cushioned track for the next workout session, it’s best for you to learn the main differences between the best treadmill types and how do they work.

Types Of Treadmills

There are several main types of treadmills for bad knees. So, let’s go over them and briefly comment on each model, shall we?

1. Manual Treadmills

If you opt for a manual treadmill, you’re relying on the belt force and your own effort. Also, you get to set the level of incline.

With this type of treadmill, you have the option to go at your own pace – which is not so great if you’re the type of person that lacks motivation.

The belts are not that long, they’re a bit bulky, and that’s why they’re one of the cheaper options on the market.

2. Motorized Treadmills

Unlike the previous one, this type of treadmill for bad knees lets you set the pace, increase or decrease the degree of incline, and access different workout programs. The most notable difference between manual and motorized treadmills is that this type is much larger and needs a permanent location.

Does the robust feature make these treadmills bad for home use?

It depends on the free space in your home.

3. Folding Treadmills

What characterizes this type of treadmills and gives it a slight advantage over the others is that it has a folding deck and console – which makes it easier to transport and store in any corner of your home.

They’re usually motorized, easily portable – and they’ll save you a lot of space.

4. Commercial And Semi-Commercial Treadmills

What’s great about commercial treadmills is that they’re meant for 12-hour workouts – if that’s your cup of fitness tea.

Newer models generally come with a cushioned deck, interactive screens, and transport wheels. The only difference between commercial and semi-commercial models is the estimated time use:

Semi-commercial ones are originally meant for users that are not so keen on running all the time. If you’re the only one using the treadmill, you don’t need a commercial one.

5. Medical Treadmills

A medial treadmill is an excellent workout machine for someone who has suffered an injury and needs an alternative to their knee treatment. The workout intensity of these machines can be adjusted to the patient’s needs.

What’s more, these types of treadmills are excellent for tracking your blood flow and muscle tone; they usually feature built-in sensors.

Your health is your number one priority!

Treadmill Vs. Elliptical Trainer – The Difference Explained

It’s time to answer the much-anticipated question here:

What’s the difference between treadmills and ellipticals?

They are both popular and widely-used fitness machines. The main difference – besides the one in the structure – is the goal you’re after.

Unlike treadmills, ellipticals are cross-trainers. These exercise machines stimulate workouts such as running or stair climbing. Although they provide you with effective cardio training, they’re usually not motorized; most of them are self-powered.

Are Ellipticals Good For People With Bad Knees?

It’s not a strict rule, but not all elliptical trainers show great results with people with bad knees. These machines require full-body activity, and there’s a chance that someone might get hurt by using them.

The Pros & Cons Of Using Treadmills

What Is The Best Exercise For Bad Knees?

Okay, we’ve gone over the 10 absolutely best treadmills for bad knees. That means the equipment is taken care of – but what about the exercise itself?

Most treadmills have already pre-programmed workouts, but these don’t suit just anyone. If you’re suffering from knee arthritis, you should take it easy once you start exercising on treadmills.

So, what’s the plan?

First, you should confine yourself to walking – meaning no intense exercises, and most importantly, no running! That way, you won’t overdo your exercise, and you’ll have the time to control your every step.

If your knees are hurting, try applying some heat for 15-20 minutes before stepping on the treadmill. You can take a hot shower or just use a heated towel to wrap around your legs.

Another thing – choose the right footwear.

You need comfy sneakers. That means you’ll have to buy a separate pair for your treadmill exercises. You shouldn’t be doing your treadmill exercises with your everyday shoes on.

Things To Consider Before Buying A Treadmill For Bad Knees

Buying just any treadmill isn’t a good idea – especially if you’re looking for a specific model of the best treadmills for bad knees. Different specifications and treadmill features will suit individual needs.

But no matter which treadmill you’re looking for and whether it’s for the purpose of light exercise or intense workouts, you should take a couple of things into account before you click that “Buy” button.

The Belt Size And Speed

Your treadmill workout will include walking and/or running. Either way, gym equipment must be safe during the entire workout process.

When it comes to the belt size and treadmill models, the belt size should be at least 48 inches long and 18 inches wide. If you’re taller than 6 feet, the belt should be at least 54 inches in order to have a proper workout.

Just as the size should suit people of all heights, the belt shouldn’t slow you down as you start walking or running.

As a rule, treadmills come pre-lubricated, but that’s always the case. So, before you set it up, check the instructions. Perhaps there’s an indication in the instructions whether you should lubricate the belt a couple more times.

Display Panels

The best treadmill for bad knees will feature interactive touchscreen control panels.

If you’re old-school, you might have trouble with the newer versions, though.

For example, it can take you twice as long to adjust the speed controls, and you might lose your desire to exercise by the time you’re done. So as not to feel out of place, go through the manual and get fully acquainted with the control panels before you start exercising.

Note that different treadmill brands could have totally different control panels.

Connecting Your Phone Or Tablet Device

Yes, it’s possible.

With these newer models, you have the chance to connect your smartphone or tablet device to your treadmill via Bluetooth. Lots of people with knee injuries rely on online exercise videos and go through with them on their treadmill indoors.

One more thing:

Once it’s connected, your smartphone automatically becomes your visual control console. Fascinating, right?


If you’re planning on engaging in workout programs for weight loss, you’ll need the best treadmill that goes up to 10 mph per hour. A high-quality running deck with a cushioning system should absorb the intensity and force of your step without collapsing – even more so if you’re dealing with knee pain.

The treadmill’s belt shouldn’t shift with each foot strike – even as you hit maximum speed – and you should be aware of the horsepower:

If you’re a person that likes to jog, you should be looking for a treadmill with at least 2.0 HP.

Weight Capacity

Since you’re on the lookout for treadmills for bad knees, you should take into account the weight capacity and whether the desired treadmill has the capacity for your weight.

Lower-end treadmills include a weight capacity of about 200-300 pounds, while some high-end models claim that their best treadmills have a running deck that can handle up to 800 pounds.

Safety Key Feature

A safety key is a crucial element to look for in the best treadmill for bad knees.

It’s a small key that’s connected to the front control panel of the treadmill. The purpose is to enable the user to stop the treadmill if a malfunction occurs or you have an accidental fall. It’s like an emergency treadmill feature for users.


Once you turn it on and officially start your workout session, try to listen closely to the noise levels.

If your treadmill is working smoothly throughout your entire exercise session, you’re good. However, if you hear rough noises coming from the machine or even short “stops” in the belt – that’s not good news. And who wants an annoyingly loud treadmill, anyway?


The incline adds a certain degree of intensity to your fitness routine.

Simply, it’s an additional function that makes your walk – or run – more interesting. It helps you vary the incline while you’re exercising. While certain machines have an in-built “hill system” that already has an adjustable incline, others need to be stopped and adjusted.

If you go for the treadmill that has to be inclined manually, you’ll have to put your exercise on hold, turn off the treadmill, adjust the incline, and get back up. Bear in mind that these types of treadmills are somewhat cheaper, though.


What if something goes wrong with your treadmill?

Even with the best treadmills for bad knees, the chances of a malfunction are not ruled out. In that event, you’ll probably want to look at the warranty of the manufacturer.

Here’s a tip:

Look for treadmills that have a lifetime warranty – that’s the best-case scenario. If you can’t find one with this type of warranty, then look for a minimum of 10 years. Who knows what could go wrong with your machine, and you don’t want to pay hundreds and hundreds of dollars for repairs every now and then.


You’re out looking for the best treadmills – but do you have the money for it? Among other factors, you have to take your budget plans into account.

The most important thing for you is to find a treadmill that is well-made but affordable. It would not be wise to get an overpriced treadmill and break your budget – or to just take any cheap treadmill and risk it breaking down after just a couple of brisk walking exercises.

Keep looking; we’re sure you’ll find a budget-friendly treadmill.
