Without that information, I don’t have the required context to answer the question well. When I get asked a question like, “How soon should I eat after working out?,” or, “How much protein should I take in?” I answer, “It depends.” I don’t feel comfortable giving a stock, one-size-fits-all answer because I don’t know off-hand the athlete’s goals, body composition, where he or she is at in his or her training/competition cycle, and so on. And when it comes to your health and fitness, you can’t end up this far off the mark if you want any hope of meeting your goals.
Wait, what?! So even if you’re using the “best” fitness tracker out there, it’s only 73% accurate? And if you’re stuck with the worst option, it’s only giving you seven percent of the picture? If an archer was off by such a wide margin, he wouldn’t just fail to hit the bullseye, he’d miss the target altogether. A study conducted by the Stanford School of Medicine put seven leading devices through their paces and found that “the most accurate was off by an average of 27%,” and “the least accurate was off by 93%.” But the dirty little secret that the fitness tracking industry wants to keep a lid on is that it’s often anything but. It might be fine to let technology guide us if the information it was providing was entirely correct. Then we’ll move on to some suggestions that help you use these devices more effectively. But before you get swept away by the hype and start thinking that your choice of fitness technology is a magic bullet that can improve every aspect of your performance, recovery, and life, let’s take a look at three of the biggest problems it poses. Manufacturers and developers promise monitoring of everything from sleep to heart rate variability, and even personalized coaching that can improve your exercise technique.
By 2020, the global market for fitness-focused apps and other devices is expected to grow to $30 billion. A report by Forrester, a leading market research company, estimates that 20% of Americans now own wearable devices, and many of these are used for fitness tracking.
