How long will the Proform Sport 4.0 last?

Thumbtacks are great for holding up pictures or important papers on a corkboard, but they do not hold up well to things that exceed half of an ounce. Have you ever tried hanging a picture frame with a thumbtack? Sure, they’re cheap, but the little point will probably begin to rip through your drywall until the picture finally falls down. If you tried to use the Sport 4.0 for anything more than a walking treadmill, then you will be like the scraped drywall and fallen picture in this scenario. And the worst part is, there are many other affordable alternatives that offer more quality. Thus, we would only recommend the Sport 4.0 as a last result for someone wanting a walking treadmill.

Brief Overview

While we do recommend beginner treadmills for those just starting out, there is a limit to how little quality you should buy. When we compare the Sport 4.0 to other treadmills in this price range, it is like a Hostess Snack that you idealize in your head when you’re on a diet: disappointing and not worth it.

Overall Quality

Maybe we should start with what little good we can say about the Sport 4.0. It comes with two cheap dumbbells and is affordable. And…oh wait, that's it. You may be walking through a sporting goods retailer or picking up some bulk goods at Costco and stumble upon the Sport 4.0. The price tag may be enticing, but please remember that this treadmill is one we use to make other treadmills look better. The Sport 4.0 is like the ugly stepchild that makes the okay looking sibling look like America's Next Top Model. <br/_><br/_> The main issue we have is that the Sport 4.0 is below average in every category. For each price range, we have our top four Best Buys. From this list, we compile averages for each feature category in order to have a reference for the top treadmills in each category. When you compare the Sport 4.0, you can see that it has many shortcomings. For example, the average preprogrammed workouts for this price is twenty; the Sport 4.0 has eight. The Sport 4.0 has an eighteen by fifty-inch walking belt while our top four average is nineteen by fifty-four. And to top it off, Proform shows their minimal support with a ninety-day warranty while other companies with models in this price bracket back their treadmills for a year. But the one feature that is probably the most telling is the build. The Sport 4.0 is way below average for this price which indicates cheap materials and low quality. We wouldn’t be this harsh if there were only a few treadmills in this price bracket. But Icon, Proform’s parent company, even produces better treadmills in this price range. The simple fact is that you can find much better quality for the same price.

In the past, we have said that Proform’s Sport 4.0 has a cool console and industrial design, but not much quality. Our reviews have commented on the small motor and big belt that combine to make a poorly made, disposable treadmill. Consequently, we have said that the Sport 4.0 is not worth the money.


All in all, we would not recommend the Sport 4.0 since there are so many other better candidates in the four-hundred-dollar bracket. This model is below average in each category and the quality is so poor that it probably won't last a walking user very long. While we do recognize the need for cheaper, beginner treadmills, we think your money will be better spent on a different model.

Rich- Should be ZERO STAR optionDec 17, 2018

Doesn't work. The treadmill makes noise but the belt won't move. The display screen shows nothing at all except "hello".

Mic- GoodbyeMar 05, 2019

I bought this treadmill today and put it together. Put my running shoes and sweats on and all this thing does is to say HELLO. I called the support they couldn't help so I'm saying goodbye to it.

elpasobearfan- Horribly Poor Non-Existent Customer ServiceDec 28, 2019

Cannot reach a live person to speak by telephone. Three times on hold for more than 55 minutes. Then disconnected. Live Chat is NOT LIVE. You must provide credit card info and subscribe to service in order to use their product.

Michelle- JUNK TreadmillApr 29, 2020

I bought this treadmill Dec 28 worked great at first ...Has a manufacturer warranty for 90 days which exp March 28 and on April 15th the belt just stopped working. We tried many ways of troubleshooting thru you tube videos and nothing. So i decided to call ProForm what do I got to lose, well that was a big waist of time i was told they can send someone out for 150 dollars and then pay for any parts that are needed or go on you tube and watch videos(REALLY) I get it I paid about 400 but still 3 months thats poor quality and customer service was useless..DONT WAISTE YOUR TIME OR MONEY!!!
