Fitness Forever

WWE wrestler Bob Backlund advocates living clean. It is in this article that his fitness program is described as follows:

"The Step Test consists of stepping up and down on a single 12-inch step at 24 steps per minute for three minutes. It might sound easy, but this test was initially designed during World War II as a way to measure cardiovascular endurance. It can wear out even the most in-shape person in a hurry."

I don't really think I want to even try to do that.
