Build Mitochondrial Health in four  minutes a day?  Try this three minute work out 3 times a day. Another good doctor –  Zach Bush, MD leads this three minute work out.  We are busy people, but even a short workout adds zing to the start of the day.  Keep your coffee if you wish, but take this first!!  Exercise is critical for overall health.  Add simple actions to daily habits.  That is how health builds.  From Dr. Mercola’s Fitness Library.
