Does a Fitness Tracker make you Fitter or Leaner...with Rowie McEvoy

Does a Fitness Tracker Make You Fitter or Leaner? Do we need to measure steps, calories, heart rate, sleep, blood pressure, and blood oxygen levels to be S.E.L.F - Strong, Energetic, Lean, and Fit? Were we weak, unfit, and fat before fitness trackers were invented? Can we be healthy and stay mentally healthier if exercise, activity, and healthy food were as normal/daily as eating, sleeping, bathing and breathing? www.maxfitnesscollege.com
