5 Myth-Busting Facts about HIIT

By LISA ELAINE HELD www.wellandgood.com

Jordan Metzl, MD, is serious about high-intensity interval training. So much so that HIIT is becoming his go-to Rx.

The New York City physician has been trying to build bridges between fitness and medicine for a while now, and with his new book, Dr. Jordan Metzl’s Workout Prescription, out December 13, he strongly makes the argument that HIIT is a workout that—despite some of the pumped-up rhetoric out there—is not just for the super fit.

Dr. Metzl believes it can be accessible to people of all ages and fitness levels, and comes with incredible health benefits for those with minimal time and equipment. (To that end, the book includes lots of at-home body-weight workouts that range from 10 to 30 minutes, so you can literally jump right in.)


“What I tried to do is use both the role of doctor and fitness instructor to offer the best information on the science of intensity…and how people can get the most benefit [from exercise] within the least amount of time,” he explains.
