The Bullworker has made a triumphant return. Now marketed under names like ISO-7X, this isometric and isotonic exercise device can give you a complete gym workout at home. I purchased an ISO-7X about 4 months ago and this really works.
The Bullworker manual was published in the 1970s, but the exercises work. It's a classic exercise manual, but these exercises will help you to tone and/or strengthen your body in weeks, not months.
