Exercise Guidelines Sports Exercise and Medicine for the Pharmacist (Fall 2012 MPA) • Physical activity guidelines (2008) • Avoid inactivity • Some better than none • Any activity provides some benefit • Metabolic equivalent units (MET) • Cardiometabolic exercise (CME) - General health and gradual weight loss = 150 points/day or ~1000 points/week
