Are Treadmills Bad for Your Knees?
Excessive use of any piece of workout equipment can overwork your knees and possibly lead to injury. It’s important to gradually introduce new workouts to your exercise routine, which is why a low-impact treadmill workout is often the best first course of action.
Walking or jogging on a treadmill can increase blood flow to the cartilage in your knees, delivering nutrients to keep the cartilage healthy. Regular workouts help promote weight loss and strengthen the muscles around your knees. Treadmill workouts can also be done in the comfort of your own home.
Not all treadmills are well-suited for knee issues. To simplify the vetting process for you, we’re spotlighting seven of the best treadmills for bad knees.
Considerations for Choosing Quality Treadmills for Bad Knees
Shock Absorption & Deck Cushioning
A treadmill’s ability to absorb shock with each stride is paramount, especially when it comes to improving the health of your knees. Deck cushioning serves a similar purpose by acting as a buffer between you and the treadmill's belt.
Deck Length & Belt Size
Deck length typically varies between 45 to 60 inches and directly impacts a treadmill’s belt size. When narrowing down on the right size options for you, your height is an important factor to consider. Individuals who are upwards of 6’0” tall have longer strides and require more running surface.
Treadmills will include safety features such as handrails, a safety key, and an automatic slow start. These features are necessary for transitioning smoothly from one speed to another and maintaining stability. You can trust that treadmills with these features are designed to further reduce the risk of injuries.
Speed Range & Incline
It’s essential to invest in a treadmill that offers a flexible speed range to give you the option to walk at your leisure or set a new speed record. Some treadmills cap out at 8 mph, while others can reach 12 mph.
A treadmill’s maximum incline can vary from model to model in this same way. Increasing incline at slower speeds can be an effective way to exercise without excessively straining your knees.
Size vs. Space
We recommend finding a treadmill that complements your lifestyle while taking up just the right amount of physical space in your living quarters. Some models are designed to fold up in-between uses, which can be great for storing in smaller spaces.
The core components of a treadmill are the motor, console, and build quality. Treadmills will either have an AC or DC motor. AC motors tend to be the more powerful but noisier option of the two, which is why treadmills with a DC motor are typically preferable in a home.
A console is where you access the control features of the treadmill. With some models, a console will include features like a fan, USB port, and heart rate monitor.
Ease of Assembly
Assembling your treadmill isn’t as strenuous or time-consuming as you might have assumed. In most cases, a treadmill will arrive partially assembled with straightforward directions attached. A treadmill's set-up can likely be completed in an hour.
Most treadmill brands will offer standard warranty coverage for the frame, motor, parts, and labor. As a general rule, warranties for labor and parts should extend for at least two years; for the frame and motor, you should expect more extended warranties from 12 years to lifetime coverage.
A treadmill is an expensive investment, and this is true for the more affordable options as well. Finding an excellent quality treadmill with the right build and features for your lifestyle is crucial. You receive value for money when you invest in a treadmill.

Best Treadmill Workouts for Bad Knees
Incline intervals are great for taking a low-impact approach while burning calories. The key is to alternate between a “flat road” incline and a high incline. We recommend short interval spurts of two to five minutes at each incline level for about half an hour.
Especially for jogging and faster running, we recommend walking at a slow warm-up pace and low incline for five minutes and then raising the speed settings until you reach a comfortable pace. Follow up with a five minute cool-down to give your legs time to actively recover.
For Faster Running
When it comes to faster running, take the reverse approach to your walking workout. Maintain a low incline and choose different speed settings to alternate between. For speed intervals, a transition between a comfortable walk and a faster run for two to five minutes at a time.
People Also Ask (FAQs)
Why do some sources say that running on a treadmill is actually bad for knees?
Not all treadmills are designed with shock absorption and durable belt material. Running on a treadmill that lacks these features can overstrain your knees, which is why it’s best to slowly incorporate low-impact workouts on a great quality treadmill.
What are the most popular and recommended treadmill brands that offer the best cushioning and shock absorption?
Schwinn, NordicTrack, 3G Cardio, Sunny Health & Fitness, and HCI Fitness are among the most popular treadmill brands. These brands construct their treadmills with particular attention to shock absorption and suspension systems.
Are there any health restrictions for using treadmills?
Depending on your individual circumstances, it may be necessary to consult a healthcare physician before beginning treadmill exercises. If approved, we recommend starting with low-impact workouts for short durations of time.
Are more expensive treadmills best for my bad knees?
An expensive treadmill outside of your budget isn’t your only option. You can find an affordable treadmill option that will work to your benefit, but you need to know which qualities to look for.
Is treadmill incline bad for my knees?
Increasing incline while also increasing speed can overstrain your knees, but increasing incline at a steady pace can strengthen your knees.
What else can one do to help knee problems?
If you have knee problems, we recommend that you consult a doctor. It’s necessary to give your knees adequate rest, elevate your legs, and stretch your limbs regularly.
Low-impact treadmill workouts may not cure your knee problems but can strengthen your legs. It’s important to invest in equipment that has been designed with durable and flexible material. The NordicTrack T Series 6.5 S Treadmill is the best model on the market for bad knees, but each of our top-ranked treadmills are also designed to exceed your highest expectations.
