How to Choose the Best Treadmill for Bad Knees

When choosing a treadmill for bad knees, there are a few key factors that you need to consider.

Cushioning System

The cushioning system is an important aspect to consider when choosing a treadmill for bad knees. Look for a machine that provides adequate support and reduces the impact on your knees while still delivering a high-quality workout.

Adjustable Incline

An adjustable incline is a great feature for a treadmill for bad knees. It allows you to add variety to your workout and also helps to reduce the impact on your knees.

Speed and Motor

A good motor is crucial for a smooth and effective workout. Make sure the motor is powerful enough to handle the speed you want to run or walk at. The faster the motor, the smoother the workout, which is especially important if you have bad knees.

Belt Size and Length

The belt size and length are also important factors to consider when choosing a treadmill for bad knees. A larger belt provides more space to run or walk, making your workout experience more comfortable. A longer belt length is ideal for tall individuals or those who want to run.

Display and User-Friendly Features

A good display should be easy to read and provide all the necessary information about your workout. It should also be user-friendly, allowing you to easily change settings, track your progress and monitor your heart rate.

Why Buy a Treadmill for Bad Knees?

Here are some of the reasons why a person with bad knees should consider buying a treadmill:

Pain Reduction

One of the primary benefits of using treadmills for bad knees is reducing pain. A treadmill’s soft, cushioned deck reduces the impact on the knees, reducing the risk of further injury. The gentle movements of walking or jogging on the treadmill can help improve knee flexibility and reduce pain.

Improved Mobility

Treadmills can help improve mobility for those with bad knees. The muscles and tissues around the knee are strengthened by gently and gradually moving the knee joint, improving joint stability and mobility. This can help reduce the risk of future knee problems and improve overall knee health.


Using a treadmill is also convenient for those with bad knees. It eliminates the need to go to a gym or outdoor area to exercise, as the treadmill can be used in the comfort of your home. This can be especially beneficial for those who have difficulty getting around or live in inclement weather areas.

Customizable Workouts

Treadmills also offer customizable workouts. Many models come with pre-programmed workouts, or you can create your own to target specific areas of weakness or pain. This allows you to tailor your workout to your specific needs, ensuring you get the most effective exercise for your knee problems.


In conclusion, finding the right treadmill for those with bad knees can be challenging. But with the right combination of features such as sturdy construction, cushioning system, adjustable incline and speed, as well as other options like built-in workouts and heart rate monitoring,

it’s possible to enjoy an effective and low-impact workout from the comfort of your home. Our top pick, the NordicTrack Commercial 1750, is an excellent example of a treadmill that ticks all the boxes for those with knee pain or injury.

Its robust construction, spacious deck, and diverse range of workout programs offer a comprehensive workout experience that caters to the needs of those with bad knees.


Is a treadmill good for bad knees?

Yes, a treadmill can be good for bad knees. It offers a low-impact workout that reduces joint stress, making it an excellent choice for individuals with knee problems. Treadmills provide a controlled and cushioned surface, which helps to protect the knees while still providing a great workout.

Are curved treadmills better for knees?

Yes, curved treadmills are often considered better for the knees than traditional flat treadmills. This is because curved treadmills have a more natural running motion, which can put less stress on the knees. Additionally, curved treadmills often have a more cushioned deck, which can help absorb shock and reduce the impact on the knees.

How do I avoid knee pain on treadmill?

To avoid knee pain on the treadmill, it’s important to follow a few guidelines:

  • Warm up: Always start with a 5-10 minute warm-up, like a slow walk or jog, to gradually increase your heart rate and prepare your joints for the workout.
  • Correct posture: Maintain good posture while running or walking on the treadmill. Keep your back straight, your head up, and your arms relaxed.
  • Footwear: Invest in good quality running shoes that provide proper support and cushioning. This will help absorb shock and reduce knee pain.
  • Adjust incline: Adjust the treadmill’s incline to reduce the impact on your knees. Running on a slightly inclined surface can help distribute pressure evenly across the joints.
  • Change up the surface: Alternating between hard and soft surfaces can help reduce the repetitive impact on your knees. Try running or walking on grass, gravel, or dirt trails.
  • Stretch and rest: Stretch your legs and allow your knees to rest after your workout. This will help reduce inflammation and speed up recovery.
