Abstract: Described is a motivational fitness device, which controls volume and power on a television or stereo component in response to the heart rate. The user must exercise in their specific heart rate target training range to keep their entertainment device turned on at an enjoyable volume. A heart rate sensing device relays heart rate to a remote control unit. The control unit receives and compares the users heart rate to the specified target range and sends infrared remote control signals (or not) to the entertainment device. If the user's heart rate drops below the target range, the volume of their entertainment device will gradually decrease and ultimately switch off until the user reacquires their target. Conversely, if the user is exercising too vigorously the volume will increase, motivating the user to reacquire their target heart rate range. This device requires no exercise equipment yet any type may be used with it.
