Chinese Stair Master. When I "hiked" on the Great Wall, it was like doing a giant stairmaster. I use FitBit and it said that day that I climbed 176 flights of stairs, that's 1760 feet! This image shows one of the massive stair masters that I climbed, I walked down and then started up. The challenging part is it was soooo hot, and the only way to cool down was in the little huts, so you had to climb in the heat, and then recover in the houe before you attempted the next set. I probably shouldn't have warn jeans! View the larger version on Flickr
