Bowflex Revolution
The Bowflex Revolution home gym ($2,400) is no cheesy infomercial product — and may just really be a revolution in home fitness. Using a resistance technology originally developed to help astronauts maintain their muscle and bone mass in space, the Revolution offers hundreds of exercises including rowing, curls, preacher curls, chest press, shoulder press, leg curls, leg extensions, and leg press. You'll be looking like Schwarzenegger in no time as the machine generates up to 300 pounds of resistance, and up to 600 pounds of leg press resistance.
