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 whipped up a quick video to catch everyone up on GreatistYou—and share some highlights from our five awesome contestants. Sit back, relax, grab some popcorn, and enjoy.
