Check out the video above to get Mike Donavanik's insight into the real differences between a work out on an elliptical machine vs. a treadmill!
What he says makes a lot of sense (that's why he's doing exclusives for us!) about the elliptical being momentum based, so the intensity has to be set higher to start getting real benefits and results.
Likewise, though, you'll want to use the incline features on the treadmill!
Thanks Mike, and keep on sending those questions to Mike on Twitter at @mikedonavanik!
