The watch is really easy to program all of your personal information onto (height, weight, etc) and is really easy to operate. I use it regularly to track my performance while running, cycling, and weight training and have been pleased with it's accuracy and consistency. A couple of the nice features are setting HR zones that you want to hit and the intervals that you want to operate in. There is a coach feature that tells you what training zone to hit but I have paid little to no attention to it.
