How much exercise is enough? This is a challenging question when handling patients with varying levels of fitness. If you remember back to your time as a student the answer was often... "It depends".  Dr. Tamara Hefferon and Dr. Eric Hefferon provide some insight on what "it depends" means.  The best fundamental resource is the ACSM guidelines.  ACSM guidelines provide a great starting point, but as we know each patient is different and exercise prescription should be tweaked to the individual. So please join us in this week's discussion and feel free to share your thoughts on exercise prescription!
