At 11 years old, Coss Marte was hustling on the streets of New York City's Lower East Side. By 17, he was making over $2 million running what he claims was the first 24/7 drug delivery operation in NYC — bringing cocaine and weed on demand across the five boroughs. Then a betrayal inside his own team brought the entire empire down, and he was suddenly facing up to 25 years in federal prison. Behind bars, a doctor delivered a brutal warning: his cholesterol was dangerously high, and unless he completely changed his lifestyle, he would have a heart attack before turning 30. Faced with that reality — and a transformative experience in solitary confinement — Coss made a decision that would change his life. He started working out in his cell, recruited fellow inmates to join him every day, and lost 70 pounds. He also did something most people in his position never do: he wrote a business plan.
