Some athletes swear by it.
Adam Archuleta works out by dropping a dumbbell, then grabbing it on the fly. When you walk into the Evo Sports gym, you know immediately that it's no place for bodybuilders. There are two rooms with weights, a water cooler, and a few machines that look like scrap-metal abstract art. And, aside from a desk, some cabinets and two chairs in a small office in the front, there's no furniture. Everything here is utilitarian, nothing wasted, nothing for show.
