Heartbeat Personal Trainer
From Sega Retro
The Heartbeat Personal Trainer is an extremely rare variation of the Sega Mega Drive, released solely in North America. It was released in 1993 for a retail price of $299 USD, with an "updated" version supposedly due for release in 1994. Being one of the rarest pieces of Mega Drive hardware (it is estimated that only 1000 units were manufactured), information on the console is scarce. The system was bundled with Outback Joey, an equally rare Mega Drive game.
The Heartbeat Personal Trainer is able to run any North American Sega Genesis game, but came bundled with exercise software and motion sensors which are only compatible with this unit. A sensor can be connected to the unit which monitors the user's heartbeat, which in turn controls the speed of an on-screen Kangaroo (Joey), the aim being to keep your heartbeat at a certain rate by exercising. Other sensors can detect movement, and past exercise history can be saved and compared with others'.
Though not a requirement, the unit was designed to be used in conjunction with exercise equipment, e.g. treadmills, exercise bikes, etc.
