The Grind

Football may be his first love, but Brandon Marshall is no longer playing for himself. After persevering through legal issues and a Border Line Personality Disorder diagnosis, the Chicago Bears wide receiver has regained control of his life. We follow the five-time Pro Bowl athlete as he gears up for the 2014-2015 NFL season, all while aiming to erase the stigma of mental health disorders.

As Brandon focuses on his off-season training, he also opens up about his past issues, including his Borderline Personality Disorder diagnosis in 2010. Through awareness and education, Brandon explains the importance of providing support for those with mental health, which is a main objective of his organization The Brandon Marshall Foundation.

Game time is almost here and Brandon is pissed off. The wide receiver signed a $40 million contract, giving the Chicago Bears what he considers a massive discount, considering his talent. The all-pro athlete breaks down his accomplishments and explains why this year is going to be his best one yet.

Think it's all endurance training and weight lifting? Well, it is...plus an intense workout regimen that doesn't stop, even during the off-season. Pro trainer Matt Gates takes us inside Brandon Marshall's FIT Speed Athletic Performance facility in Weston, Fla. to find out how NFL athletes stay in shape year-round.

Brandon stops by the Under Armour offices to explain his keys to success (it's all mental) and how maintaining his focus and dedication to the game has helped give him an edge above his competitors.
