Soloflex is a technology all its own and prides itself on having no cables or pulleys. It utilizes a unique variable resistance elastomer made of heavy-duty rubber called the Weightstrap. Each weight strap can produce up to 100 pounds of weight resistance, and the Classic comes with 405 pounds of Weightstraps. The patented barbell works like a free-weight barbell, but its solid and permanent installation prohibits uneven lifting. Along with the Weightstraps, the Classic comes with dip bar, curl tubes, and free weight rods, for those who want to add a little extra to their workout. There's also a helpful wall chart, user guide, and even a workout video. Soloflex has thought of it all, so while this machine may be a departure from the norm for you, they put you right at home with it. It's easy to set up and even easier to use, what more could you want from a Best Buy.
