Welcome to GreatistYou, a new social experiment where we see what happens when five people decide to change their health—and broadcast their journeys for everyone to see. Four goals, five contestants, and six weeks to crush said goals for the promise of a better life (oh, and $1,000!).

The first season of GreatistYou is officially over, meaning you’ve got six weeks of running, sweating, punching, and dancing to catch up on. We invited Jessi Kneeland to Greatist HQ to discuss everything that happened over the past month and a half—and give some final advice to our contestants.
