Treadmill Speed is measured in Miles Per Hour (mph). Average running speed is 5-9 mph.

0.5-12 mph

Treadmill Incline measures the angle of the deck, and how steep it is relative to the floor (0% is flat, and 15% is like a steep hill).


The Treadmill Motor is what turns the belt as you run. We recommend at least 2 HP (Horsepower) motors, 2.5+ HP for jogging, and 3.0+ HP for running.


Treadmill Deck dimensions are measured in inches: Width x Length. The wider and longer the deck, the safer it is (55-60 inches long recommended for running).

20" x 60"

The Treadmill Belt is the surface you run on. The thicker the belt, the less impact on your joints. At least 2-ply (1 inch) recommended.

Power incline can angle the deck by up to 15 percent. Incline can be automated by preset workout programs, or controlled with buttons on the handlebars and console.
