Most Wanted: TREADWALL

TREADWALL

Everyone knows that climbing is a great workout — but installing a climbing wall in your house isn't exactly a viable idea. Enter the Treadwall . This innovative machine offers a 4 foot-wide climbing area and acts just like a treadmill, only for climbing instead of running. If a vertical climb sounds too dull for you, pony up for the Pro model and tackle inclines/declines of +5 to -20 degrees — or as we like to call it, Spidey-training.
