These bands, bracelets, and watches still hold the top spot with the ACSM for 2016 with consumer's spending of over $12 billion in 2015 and expected growth to $25 billion in 2019. These devices allow you to track your steps, weight, pulse, sleep activity, and more. If you have a FitBit or Jawbone already, it might be time to upgrade to a newer version with more capability and better data analysis. If you’re worried about fashion, biowearables (or “tech tats”) are the latest trend soon to hit the general market. They'll allow you to wear your tech on your sleeve and track heart rate, blood pressure, and other data without being too noticeable.
