One year, we purchased pulse rate monitors, because we teach the children early on how to monitor their heart rate. When they are really young, we show them how to put their hand on their chest and feel their heart beat, and experience their hearts beating faster or slower. As they get older, they can use the wristband heart monitor to monitor their pulse while they are exercising. The idea is that you want to get the heart rate up to a certain level when you exercise to really get an aerobic benefit from it.
