The Spirit XT285 is a step up from the 185 offering a little heavier grade treadmill, bluetooth for use with the Spirit Fit App, a larger HP motor, longer 20" x 60" running surface, audio jack with speakers, built-in HR receiver to accommodate runners and higher weight capacities.
Spirit was the fiirst manufacturer in the industry to offer a folding treadmill that would stand up to heavy use. The Lift Assist hydraulics help lift the deck into the storage position while the Safe Drop feature slowly lowers the treadmill deck back down into position making it uber easy on the back.
Very good value with a 10 year parts warranty.
