On a very chilly January morning, Coss Marte and I ventured out to his rooftop to finish the other half of his exercise book which is set to be released later on this year. I had the privilege of meeting and getting to know Coss this past summer and his will to succeed is inspiring. Coss developed an exercise program without the need for any equipment while serving a sentence in his 9x6 prison cell. Now he owns and runs his own studio, gives lectures around the world and transforms the lives of others. To hear his story check out: conbody.com.
