Is There A 500 lb Weight Capacity Treadmill?

Yes there is and I have done some research on these. It is the 500 pound professional that fires me up. These hard-working, focused athletes are in it too. Do not underestimate these athletes.

We all come in different shapes and sizes. A 500-pound athlete is just as determined as someone less than 200 pounds.

If you want to invest in a treadmill heavy weight capacity has to come into play. You don’t want to waste your hard earned dollars on a heavy-duty treadmill that cannot keep up with you.

Treadmills With 500 lbs Weight Capacity

These heavy-duty treadmills are far more reliable than your average traditional treadmill. but also cost more.

They have a stronger frame and unmatched versatility. Let’s check out a few and see if they would not be a perfect fit for your fitness needs.

Please keep in mind these treadmills are not cheap.

They are for the serious investor who desires the very best in high weight capacity workout machinery. They are ultra-premium treadmills for good reason.

Bariatric Treadmill Considerations

Bariatric treadmills are state of the art treadmills with 500 pound weight capacity capability.

Do you have a BMI score above 40? Are at least 100 pounds over your recommended weight?

If so, the medical community state you are a good candidate for bariatric surgery also known as weight-loss surgery.

If you are currently 500-pounds do not lose hope. Don’t ever think you cannot get to your goal weight.

Greater Stability & Power

An exerpeutic treadmill will provide the stability and power that you need while you are currently at this weight. Stay focused.

You can do this and get below 400, then 300 on to 200 pounds or wherever your fitness goals lead you.

The most powerful treadmill I could find that was reasonably priced and could support a 500 pound athlete is the Precor TRM 885 Commercial Treadmill.

Precor TRM 885 Commercial Treadmill

The maximum user weight for this behemoth is 500 pounds.

High Speeds

It ranges in speed from 0.5MPH up to an incredible 16 miles per hour (under 4 minute mile pace).

Obviously, that is not the goal here. If you are just under 500 pounds this is a great option.

Wrapping Up

You want to always consult a Physician before starting any fitness program. There is heart and desire in all of us.

Athletes and working professionals who range in weight from 300 to 500 pounds are no different than a tiny elite Kenyan. Everyone wants and desires to be fit.

Treadmills are an investment in yourself. The higher end models cost more because they are more reliable, can withstand the extra stress and are durable.

Always purchase quality. There are plenty of cheap treadmills in the marketplace to choose from.

Choose wisely when it comes to investing in one that will last. No one needs to be running at 15 to 16 miles per hour. I am a 2:19 marathoner and I could only last at that speed for a few minutes tops.

How Trustworthy Is A Treadmills Weight Capacity?

If you have chosen to go with one of the treadmills mentioned above always go with top manufactures like SoleFitness, NordicTrack and LifeSpan Fitness.

Find the best treadmills (of which many are listed) and rely on the specs and longevity of the company that builds them.

Always use treadmills at your own risk and don’t be in a rush to get fit. The body takes time to adapt to any stress load you place upon it.

Universal Heavy-Duty Specs

This is universal. It doesn’t matter if you are 140 pounds or 500 pounds. The body adapts to stress but it cannot be rushed.

A high weight capacity treadmill is always going to cost but also keep in mind it is a one-time investment.

Choose quality and you will get quality back. If you choose cheap expect a treadmill that will not last that long.

Why Curved Treadmills Are Your Best Bet

Curved treadmills have the highest weight capacity of any treadmill in existence. I saved this portion for last because it is a style of treadmill so few people know about.

It also requires more out of the user than any other treadmill.


There is no electricity involved. The user propels the treadmill belt which means you burn more calories, have a higher heart rate and get fitter fast.

Higher Quality

Curved treadmills cost the most and for very good reason.

They do not require electricity, carry incredible weight capacity capability and have near zero maintenance costs.

If you are interested in a heavy-duty treadmill curved treadmills are your best bet. It doesn’t matter if you are 150 pounds or 500 pounds they can handle it.

A non-motorized treadmill will always last longer.

The price is higher but would you rather invest and save for the long-term or buy cheap and keep having to spend? Something to consider.

Non-Motorized Curved Treadmill Machines

Assault Fitness AirRunner
Max User Weight: 350 pounds

The Assault Fitness AirRunner is one of the most expensive but longest lasting heavy duty treadmills you are going to find.

The athlete, regardless of weight, is going to see the long-term return on investment (ROI) when choosing this behemoth.

Burn More Calories

If you want to burn more calories, save yourself the extra electricity costs of using a treadmill and get fitter faster this is the one.

Curved treadmills burn up to 30 percent more calories compared to regular flat treadmills.

The belt? Yeah, it lasts up to 150,000 miles before you even have to change it. Try getting that return in investment with any other treadmill. Good luck.

Non-motorized treadmills force you to run on the balls of your feet which force you to run with a more economical running stride.

This is why I am a huge advocate of these treadmills.

Assault Fitness AirRunner Curved Treadmill

400 pound weight capacity at over 4MPH, 800 pound capacity at lower speeds.

The last motor-less treadmill to keep in mind as you make your investment decision is the Woodway Curve Cordless Treadmill.

There is no maximum speed on this gem.

One of the best things about cordless treadmills is they save you money.

They do require you to work harder. It is you that propels the belt. There is no electricity.

150,000 Miles?

The belt will last up to 150,000 miles at a minimum. This cannot be matched by any other traditional treadmill.

The Slat Belt system the woodway curved treadmill provides allows for near frictionless movement.

The investment is higher for curved treadmills but always remember how long they will last and how much money you will save.

No motorized parts means no need to spend extra money on additional parts. If you are a gym owner these types of treadmills are one of the best investment you can make for your fitness gym or personal use.

In this exhaustive overview of heavy-duty treadmills I have been as extensive as I could be. I hope these treadmills will give you some ideas and help you make the educated purchase of your choice.

Always remember, you get what you pay for. Quality will cost but will also last the longest.

Heavy-duty treadmills have motors and some do not as discussed here with curved treadmills.
