A Florida inventor has come up with a gym contraption that eliminates the need to lug free weights around. The Selex machines offer the convenience of Nautilus, housing weights alongside a barbell. Weights can be added or taken away with the flip of a tab. The founders expect the system, licensed to Pyramid Fitness Industries, of Sharpsville, Pa., to be easy to sell, since it's a variation on an established product, not a new concept.
