The Starting Strength community is a goldmine of intellectual horsepower, and Jonathon Sullivan - or Sully as we know him - is one of the main reasons for that. Sully is an MD with over 25yrs experience in Emergency Medicine, a PhD who has studied the effects of brain ischemia, and a Starting Strength Coach who runs Greysteel Strength & Conditioning in Michigan. He is now primarily a barbell coach with a mission to help older people get stronger, get healthier, and age with grace and dignity.
