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!).

Are you as excited for this fight as we are?! This weekend Regina (@greatistregina) will step into the ring with her Muay Thai instructor for a sparring match. She’ll be judged on her form and style, and the results will determine whether she’s completed her GreatistYou goal.

Get pumped, guys. It’s all going down soon. Stay tuned to see what happens.
