Michael Phelps – Swimming, USA

Michael Phelps is perhaps the most famous Olympian of all time, and statistically the most decorated by a wide margin, with his 28 medals. The road hasn’t been easy, however, as he’s suffered from suicidal thoughts, severe depression, and documented alcoholism…

His six medals in the 2016 Rio Olympics are a testament to his determination, as merely two years prior, Phelps was checked in to a rehab facility for the second time in a ten-year span. Since that time, he hasn’t had a sip of alcohol, he sleeps a minimum of eight hours a night, and his body fat percentage has dropped by several points.
