The Aerobics Joystick by Suncom promised an improved cardiovascular system from using this device that interfaced between most standard exercise bikes and an Atari 2600. While the fire button-equipped joystick worked with shoot-'em-ups, best results were obtained with driving games (particularly, Suncom said, Enduro). The faster you pedal, the faster you drive. What could be more boring than pedaling a stationary bike--or worse exercise (thumb and forefinger excluded) than wiggling a joystick? Suncom combined the two activities to their mutual benefit. Price was $39.95.
