Best Treadmill for Bad Knees

If you have bad knees, you need to incorporate cardio into your everyday routines in safe and smart ways. Low-impact workouts can be as effective as high-impact workouts, especially when exercising arthritic workouts. With the right treadmill, you will have full control over your exercise’s intensity and make adjustments in seconds.

Modern treadmills have become an all-in-one solution to exercise challenges. They are equipped with cushioning underneath the conveyer belt, which reduces the impact on the feet and helps prevent any kind of leg injury.

However, choosing the best treadmill for bad knees can be challenging if you don’t know what to look for. Fortunately, I’ve compiled a list of the best treadmills on the market that anyone with bad knees can trust.

Why Most Treadmills are Bad on Your Knees

Most treadmills on the market are designed to handle high-intensity workouts, and the decks lack extra cushion to absorb impact. Every step that hits the treadmill deck sends a wave of force up your body, starting from the ankle up to the spine.

Some people say that the impact force on a treadmill deck is double that of your weight. This can cause more harm to your joints, especially if you already have an injury. All you need is a treadmill with a sufficient shock-absorbent cushion that can absorb some, if not all, impact.

How to Use a Treadmill with Bad Knees

Running on a treadmill is different from running outdoors. Individuals who don’t take the necessary precautions to keep themselves safe end up hurting themselves. Here are some safety tips to keep you safe from knee pain when exercising on a treadmill:

  • Treadmills have several control buttons and switches, and you should be familiar with these before exercising.
  • You should walk on the treadmill instead of running to avoid further knee injuries and pain. You can opt for brisk walking at a speed of 3 to 4 mph as it provides an effective cardiovascular workout that strengthens your legs, knees, and glutei.
  • Use high-quality shoes that minimize the impact on the knees and joints. It is advisable to use low-heeled and athletic shoes to maintain proper balance while on the treadmill.
  • Shorten your stride so that your feet will hit the ground directly under the body. Additionally, a short stride allows you to walk efficiently and increase the speed of the pace.
  • Use good quality knee braces to prevent your knees from repeated injury. It also supports and stabilizes your bad knees.
  • Socks can also offer sufficient cushioning to pad your feet. Wearing high-quality socks minimizes the impact of running.
  • Avoid looking sideways, down, or backward. Always look forward to maintain balance.
  • Adjust the machine’s inclination and speeds to the lowest levels. Start slowly and gradually increase the workouts’ intensity so that your body can adjust.
  • Don’t hold the front of the side railings or handlebars since they can throw the balance off.
  • Before you start exercising, ensure that the safety key is attached to your shirt.
  • Begin your routine with 7 to 10 minutes of warm-up workouts.

Best Treadmill for Bad Knees: Buying Guide

There are some main features that you should look for when buying a treadmill for bad knees. You do not want to spend your hard-earned cash on a treadmill that will not work for you. Here are some factors you should consider before making the final decision.

Running Surface Area

The running area should be ideal for your stride width, gait, and stride length. A small surface area restricts your walking style, which adds stress to your knees. So, before choosing the best treadmill for bad knees, ensure that the running surface suits you.

Deck Size

If the treadmill’s deck is not too lengthy or heavy, it can be transported and stored easily. This is an important element available in all treadmills for bad knees out there. A small deck size also makes it highly portable.


The inclination shows the downhill and uphill movement and helps burn 40% more fat than flat trainers. However, you should consult your doctor to determine how much inclination your knees can handle. Check the degrees of inclination offered by your favorite treadmill. Sometimes, even level-1 inclination can hurt your knees.


Although speed should not be the main factor when you have bad knees, it’s worth considering when you recover. In fact, most therapists use variable speed walks to help in recovery. Most high-quality treadmills have variable speeds ranging from 0 to 10 mph. Other models can run up to 12 mph, which is a great choice for those who like HIIT sprints and workouts.

Safety Features

Treadmills come with safety features like a safety key, handrails, and an automatic slow start. These features are crucial for transitioning smoothly from one speed to another and maintaining stability. If you find a treadmill with these features, now that it’s designed to help minimize the risk of injuries.

Shock Absorption and Deck Cushioning

A treadmill with excellent shock absorption is important, especially when you want to improve the health of your knees. Deck cushioning also acts as a buffer between you and the treadmill’s belt.

Ease of Assembly

Assembling your treadmill isn’t as time-consuming and strenuous as you might think. Mostly, treadmills arrive partially assembled with simple directions attached. You can set up your treadmill in an hour.

Ease of Storage

Foldable treadmills are perfect for small homes, apartments, and in the room of a knee patient. Ensure that the treadmill is easy to fold and doesn’t require you to sit down.

Ease of Use

You must understand the adjustments and controls of your treadmill. Ensure you know everything from assembly, maintenance, and regular usage.
