The 500Sr offers plenty of workout flexibility, with an easy-to-read console that supports several different program types, including manual, fat-burning intervals, glute max hill climb, target heart rate, and custom trainer. The latter program is particularly valuable over the long term, as it lets you vary your workout depending on your mood. This not only keeps your attitude fresh, but it also makes your overall training regimen more efficient by challenging your body in different ways. It's also a breeze to track your workout progress thanks to the blue backlit LCD, which displays your time, pulse, calories, intensity level, RPM, speed, distance, and watts. And no workout is complete without a little motivational music, with is why the 500Sr comes with a set of built-in speakers and a plug-in jack for your MP3 player. Once you're plugged in, you can listen to your favorite playlists and tune out the rest of the world as you cycle through the imaginary hillsides.

Other features include contact pulse sensors in the handgrips for reading your heart rate, an accessory holder on the console for magazines or books, a built-in Smart Fan, and a weight capacity of 275 pounds. The 500Sr measures 67 by 31 by 12.5 inches (W x H x D), weighs 119 pounds, and carries the following warranties: limited lifetime on the frame and brake, three years on parts and electronics, and one year on labor.
