ConBody: The Revolutionary Bodyweight Prison Boot Camp, Born from an Extraordinary Story of Hope Spiral-Bound | March 20, 2018

An incredible bodyweight-only fitness book written by Coss Marte, a former Lower East Side drug dealer who found purpose and inspiration in prison—by developing a kick-butt workout.

ConBody is former Lower East Side drug dealer, Coss Marte’s, bodyweight-only approach to fitness. Created in prison with only the space of his own cell and no equipment to work with, Coss designed a plan that helped him go from dangerously obese with a five year prognosis to losing 70 pounds and training other inmates.


Before prison, Coss was flying high, dealing drugs, and making money hand over fist as a teenager. But after watching his life and those of his loved ones fall apart, he realized things had to change. Once he saw that his workout plan was not only effective, but accessible, he knew he’d found a pathway to health and ultimately to a new life.

When he left prison, he returned to the Lower East Side where any betting person would tell you he’d be back slinging crack in no time. But instead he worked out in his old hangouts and gained a small following that turned into an acclaimed business winning entrepreneurial awards and the support of Shark Tank’s Barbara Corcoran.

Coss’s method works. Just ask the thousands of clients who attend his classes. These exercises are for anyone, anywhere. Male, female, rich, poor, all you need is yourself and the space of a jail cell to get to work. It’s perfect for busy lifestyles on the go and can be done in hotel rooms, small apartments, and in your backyard. With fun, engaging exercises, ConBody will help you get and stay healthy.
