The Seattle Seahawks have instituted mandatory yoga classes for its entire roster.

Yoga was an optional activity last season but it became highly popular that the decision was made to make it mandatory for 2013.

Pete Carroll has everyone in the organization practicing positive thoughts and actions.

"Do your job better than it has ever been done before," says Carroll.

The Seahawks also work with sports psychologist Mike Gervais.

"We do imagery work and talk about having that innovative mindset of being special," Russell Wilson says. "We talk about being in the moment and increasing chaos throughout practice, so when I go into the game, everything is relaxed."
