I love training myself and clients, with heart rate monitors because it gives me imperial data to work with. Its nothing like being about to measure numbers, with out having to crunch numbers. At the end of a work out, I know what the average heart rate was, the fat percentage burned, the max heart rate, how effective the workout was. This comes in hand with not only weight loss clients, but clients looking to build muscle or maintain their current builds.
