Gamercize’s GZ PC-Sport has surely been devised for those who can pat their heads and rub their stomachs at the same time. Place it under your desk, connect to your USB mouse or keyboard, and start walking. If you slow down or stop, the peripheral will not work. We call that massive incentive. The Sport lets you know how well you are doing and gauges which level you are on. The Power Stepper steps up (pun intended) when you adjust it to a brisk walk and the Endurance Cycle lets you pedal away while chatting, e-mailing, or other online activities. You can purchase a full package or simply purchase the PC-Sport and use your own exercise machine for prices beginning at £69.95 (~$140.00.)
