Spirit XT685

Spirit XT685 treadmill


If you’ve been searching for a treadmill, you have been for sure recommended to try a model from the Spirit XT line. All the products from this line are famous for their reliability and high performance, from the low-entry version, XT185 – to the high-end version, the XT685.

The XT685 from Spirit is a sturdy, upgraded treadmill that is definitely worthy of your time, if you’re looking for a unit in the $2000-2500 range. It rates well in all categories, so we thought we should definitely try it. There is one uncertain aspect, and we can’t seem to shake it off. It’s the fact that Spirit is an economic brand, so we ask ourselves “Can we really rely on this unit?”

Spirit XT685 receives many points in many departments, such as sturdiness, programmability, functionality, program variety and motivational tools. But there is a question mark in the reliability area, since Spirit is, after all, an economic brand. Even so, we do recommend this high-end treadmill, and here are all the good reasons why.


When we decide to try a high-end treadmill, we are primarily looking for a strong motor. The XT685 satisfies our expectations with a sturdy, powerful 3.5 hp AC motor that supports our highest demands successfully. We realized even from our first workout that this treadmill is worthy of our time.

Spirit designed a series of similar treadmills. The XT685, XT485, XT385, XT285 and XT185 are almost the same machine. Almost. One of the key differences resides in the belt dimensions. The XT685 unit adds an extra 2”, which means taller and heavier walkers and runners can use this treadmill. That’s one great perk and also sine-qua-non for high-end units.

Once these very important features were checked, we carried our testing on to the cushioning options. As it turns out, Spirit really put some energy into the entire cushioning strategy and the result is quite satisfactory. We felt no injuries, no stress after an intense Fusion workout. That’s quite something, and is available with all the models, even the $1,300 version.

Talking of Fusion, this is one of the highlights of this treadmill. Those of you interested in resistance, cardio and strength workouts will be happy to know that Spirit outdid itself with the XT685 unit (click here for the product page at Spirit website).

Another cool thing is that you get to insert age and weight prior to workout, which means the feedback on calories and heart rate is as accurate as possible. The workouts are quite diverse and programmability options were generously added.

Having a muscle activation profile is greater than we expected. It keeps you constantly aware of which muscle groups are activated and when. It’s a great way of keeping track of your performance. We totally love this feature.

We also dig the remote adjustment keys. These keys are incorporated into the handlebars and allow you to adjust speed and incline without having to slow down, lean towards the console, press those buttons and come back. That’s a major turn off, but luckily you don’t have to think about it when working out on the XT685.

All the extra perks such as the cooling fan that works flawlessly, the speakers that are also quite satisfactory, unlike many other treadmills out there and the warranty that boosts reliability are definitely worth your while.

Main attraction

The main attraction of the XT685 treadmill is the unit itself. It comprises all the benefits of a high-end machine, made of heavy steel and powerful enough to be used at the gym.


But there is one thing that we can’t get off our mind. Spirit remains an economic brand, which means we can’t really indulge in 100% confidence that this treadmill is the best choice in the $2000-2500 range. We’ve received only good comments about it so far, that’s why until contrary evidence we have trust in its long-term performance.

All in all, the XT685 is a catch: it’s nice to look at, it’s sturdy, offers a stable mount, helps you keep cool during toughest of workouts, provides an attractive variety of programs, especially for consistent cardio enthusiasts and offers an abundance of programmability options.
