The Schwinn 870 is an upgrade from the Schwinn 830. Everything gets beefed up a notch. The gradient is raised to 15% and you get an extra 4 workout apps, for a grand total of 26. The top speed is 12mph and the motor gets a bit of a boost to 3.0 CHP. So this treadmill is competing with a lot of other brands. It uses Bluetooth as well and this lets you sync your workout data to the online diet and fitness tracking software myfitnesspal.
You also get a USB charging point so you can listen to some music and charge your phone at the same time. The softtrack cushioning makes taking long runs really comfortable leaving you less stress and strain on your body the days after your workout. There are really nice acoustic speakers which deliver a really big sound plus there is a fan to cool you down when thinks get intense for you.
