Unleash the Beast: A Journey to Rediscover the Greatness Within

“Mark is a real inspiration—not only in the way he transformed his life, but also in how he’s now looking to share his success to help others achieve their goals. Mark’s journey from couch potato to Ironman is both emotional and powerful, and the lessons he learned along the way are invaluable for anyone looking to make a change in their life.”

—Joy Bauer, MS, RDN, health and nutrition expert for NBC’s TODAY show and best-selling author of From Junk Food to Joy Food
