The Commercial 2450 is NordicTrack’s top-of-the-line folding treadmill, and you can score one for $300 off this season. Building on the already-solid specs of the Commercial 1750, it has a slightly wider 22- x 60-inch running deck, a top speed of 14 mph and a higher 400-pound weight limit.

For your next trek: NordicTrack's highly rated hiking treads are on sale too. Both the X16 and X24 have a maximum incline of 40% and automatically adjusting fans. The X24's display is slightly larger, so it's the better choice if you want a truly immersive workout.
