Actually I have two. When I bought my eliptical it came with a HRM that you wear around your chest and if you hold on to the bars it will tell you your heart rate. I really like it. The maching will adjust to what your heart rate is to keep the maching at the right level. The other one I have is a richard simmons one that goes around the chest and has a watch that recieves the transimission. So you can wear it walking to or doing what ever, so you are not tied to a machine. I would recommend getting one. The ones that go on the chest are more accurate from what I have read than the finger ones. They really help you keep your heart rate to the maximum rate for aerobic activity.
