This is entirely up to you. If you've never set foot on a treadmill or laced up a pair of running shoes before, it's obviously a good idea to seek some expert guidance. But, that guidance need not be a pricey subscription. Many free or low-cost apps are available that help you keep track of your runs, make plans to advance your fitness level, and even provide pre-designed programs for meeting long-term goals like running a 5K or completing a mile run in under a certain amount of time. That said, if you're the kind of person that will actually feel more motivated by the presence of a persistent subscription that might hold your hand a bit more and keep you from turning your new treadmill into a coatrack a few months later, then, by all means, consider one of the companion services mentioned here, or an alternate option that better suits your budget and fitness goals.
