Mike Lee shares his personal journey of using technology to track his health and wellness. After a health crisis in 2014 that required thyroid surgery, Lee began using various wearable devices and apps to monitor his activity, sleep, nutrition, and progress in losing weight and running long distances. Over time, Lee was able to lose 75 pounds and run 628 miles in one year through diligent self-tracking with devices like Fitbits, Jawbone bands, and apps like MyFitnessPal and MapMyWalk. He emphasizes choosing a tracker that fits your lifestyle and taking small, consistent steps towards better habits through technology.
