Each and every day, Jake Prusha, a member of the US Coast Guard stationed in Boston, takes part in a grueling challenge called the "Murph" workout, which honors a Navy SEAL who was killed in Afghanistan back in 2005. Prusha's doing this for 100 days - not to get fit, but to raise awareness of members of the military and first responders who are grappling with mental health challenges. Jake talks with Nichole about his story, why this challenge means a lot to him, and how you can help him raise money for the Wounded Warrior Project. (Find Jake on Instagram at @jakeprusha.)
