Last updated on July 4, 2021

When you’ve got knee pain, your cardio machine exercise equipment options are severely limited. This is especially so when it comes to training for cardio endurance and fat loss. Most exercise options will involve putting direct impact on the knee joint and therefore stressful on your knees. Yet there is one form of cardio training that is extremely low-impact and, therefore, a fantastic choice for people with knee pain. This is the elliptical machine. Not all elliptical machines, though, are equal. Because you can’t afford to gamble with the health of your knees, we have gone the extra distance to find the three best elliptical trainers for people with bad knees at different price ranges that will suit your budget and will allow you to achieve your fitness goal.


In this article, we provide in-depth reviews of the three best elliptical trainers for people with bad knees, along with an overview of what you need to look out for when buying a zero-impact elliptical and some tips on how to stay safe when performing an elliptical cardio workout around bad knees.


Key Features for Ellipticals and Bad Knees


  • Stride Length – you need full range of motion to prevent knee strain!
  • Rear wheel drive – prevents forward lean which stresses the knees!
  • Low Step on/off height – 8 inches or less is ideal!
  • Smooth, jerk free operation – the jerkier the operation, the more strain your knees will experience!
  • Large flywheel – 7kg or more will deliver the smoothest operation!

Training with Bad Knees


There is a lot of evidence to show that training around knee problems is good for your health. Apart from improving your cardiovascular endurance and helping you burn calories, it can directly improve the health of your knees by improving the blood flow so that oxygen and nutrients strengthen the cartilage and the muscles that support the knee joint. The weight loss that results from cardio exercise will also help to reduce the strain on the knee joints.

There are a number of causes for knee problems. A person may suffer from rheumatoid arthritis, meaning that they will have arthritic knees for the rest of their lives. Getting into the lifestyle habits of regular zero impact exercise that strengthens the cartilage and muscles around the knee has been identified by osteoarthritis specialists as one of the best things that can be done for this condition. Other people may have suffered a knee injury during sport or as part of their everyday activities. This training on a zero-impact elliptical will allow them to maintain their fitness level, while strengthening the area around the knee. This will prevent them from going backwards in their training and conditioning. Other people may be post-surgery and in need of a gentle rebuilding program. A zero-impact elliptical is, again, ideal for this purpose.

Training on an elliptical is far easier on bad knees than using an exercycle. Another excellent zero impact choice is the rowing machine.


What to Look for in a Zero Impact Elliptical


There are 5 things to look out for when buying a zero-impact elliptical good for bad knees and great elliptical workouts:


Stride Length


The stride length is the maximum distance that you are able to move your feet on the elliptical foot platforms. If you are unable to get a full, fluid, natural motion than your knees will be affected negatively. For most people of average height, an average size stride length of between 18 and 20 inches is ideal. If you are 5 foot 6 or under, you will be able to get away with a shorter stride length, but keep in mind that other users of the machine may not be able to use it effectively.


Drive Position


The motor of an elliptical consists mainly of its flywheel, which drives the elliptical pedal motion. This is known as the drive of the machine. It can either be located at the front or the rear of the elliptical (some newer machines are also having centrally located drives). You will usually find front drives on lower-priced ellipticals. These require that the user lean slightly forward when performing the exercise. This is not ideal as it can place some strain on the joints. A rear drive elliptical will allow for a more freestanding, natural and less joint impacting elliptical movement and is, therefore, preferred for people with bad knees.




When we are talking about height, we are referring to the setup height required to get on and off the elliptical. You wanted to be as low as possible to reduce the impact on your knees.




The last thing that a person with bad knees wants is to use an elliptical that provides a stuttering, jerky motion. So before buying, be sure to check the reviews to see what the actual performance is like. You want to read that people are experiencing a fluid, natural and smooth elliptical motion without any jerkiness.




The larger the flywheel, the smoother the elliptical motion will be. You should machine that has a flywheel weight of 7kg or more.



Elliptical Safety Tips


  • Be sure to hold the handle during your training session. This will, not only engage the upper body, but provide support and stability while you are working out.
  • Keep your feet in line with the pedals, rather than having them angled either inward or outward.
  • Maintain an upright stance throughout your exercise session – do not lean forward or around your lower back.
  • Do not lift your heels of the pedals – maintain a flat foot position at all times.
