This machine kicked my butt today. I am seriously sore. If you haven’t tried a treadclimber yet, you need to find one. It’s a cross between a stepper and a treadmill. It has a separate treadmill for each side and it moves up and down as you are walking. It really feels like you are walking uphill in sand. I had been on some of the early prototypes at fitness shows in Chicago and San Francisco when these things were released, but I had forgotten just how good they work. The Wellness Center in Galax has one, and it stays in use all the time. If you want a new challenge, you’ll have to check this beast out.
