Very convenient to use! It's really simple yet very powerful at tracking our clients' fitness progress throughout their entire workout experience with us - not that they all know this is what we do here but it seems like everyone just wants some kind of quantifiable proof as far as how good or bad I am doing in my workouts vs other people who are also working out there during those times when you can actually see them/me too!! This helps me track things which might be hard if i'm only by myself
