The Entertrainer is a device intended to motivate lazy people to work out. It is a wireless heart rate monitor that doubles as a universal remote. You can either enter in a heart rate that you want to maintain over the course of your workout or enter your age and the intensity you want and it will calculate a target heart rate for you. If your heart rate starts to decrease much under your target heart rate the device will lower the volume on your TV to give you a heads up that you’re not working hard enough. If you continue to slack, it will turn off the TV altogether until you pick up the pace again.
