Shop IRON COMPANY for environmentally friendly fitness equipment and rubber gym flooring. These are items deemed to be environmentally friendly through manufacturing processes which incorporate post-consumer materials within their finished product or have very little dependency, if any, on our power grid. Choose from rubber gym flooring and even bumper plates made from crumb rubber derived from car and truck tires diverted from local landfills. Our cardio equipment shown here includes exercise bikes, treadmills, steppers and elliptical trainers that are either self-powered or, as our SportsArt ECO-POWR line demonstrates, has the ability to push human generated energy back into the power grid and lowering the facilities electricity costs.
