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!).

If you’ve been too busy to check out the action, don’t sweat it. We’ve got a quick video to catch you up. Sit back, relax, and let GreatistYou recapper Jeremy Glass run through the highlights.
