What can these things tell you?
No two devices report exactly the same nuggets of data, but they all focus on exercise and health metrics”miles jogged, steps taken, calories burned. You can drill into the data of a specific workout session or track 24-hour totals. Some monitors also rate sleep quality.
How do they work?
Accelerometers record footsteps and sleep-time restlessness. GPS tracks your location. Altimeters follow changes in elevation. And sensors that monitor skin temperature and perspiration can even help divine how many calories you’re burning. Built-in displays can show snapshots of data at a glance, but for rich charts detailing health and exercise progress, you’ll need to connect to a PC or mobile device.
Will a body monitor make me healthier?
No, that’s your job. What monitors can do is nudge you to be more active and help you set goals. You’ll begin to figure out which activities burn the most calories and which lifestyle habits affect sleep most grievously. Ideally, the data will drive your decisionmaking and you’ll become addicted to personal improvement.
Thanks to regular firmware and software updates, various monitor features”algorithms, mobile apps, and even basic functionality”can change and improve over time. Nonetheless, no single monitor does everything. For this reason alone, the model you choose will depend upon what you’re trying to accomplish. Some focus on individual workouts, reporting exactly how far, how fast, and how hard you pushed yourself. Others are geared toward broader lifestyle goals. Assess your needs and match them to a device with complementary features.
