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!).

Day two? Already?! Believe it, people. You know, making a major life change is supposed to be hard, but Regina Postrekhina (@greatistregina) is making this whole process look like a piece of cake… or possibly an even easier-to-bake dessert. Regina’s not letting her bad knee get the best of her and has started swimming sprint laps to up her endurance.

Sprinting through a pool can be pretty tough on its own, but documenting said training and showcasing it for the world to see truly takes a Liam Neeson-level set of skills. Alongside her grueling training schedule, Regina found the time to take over our Snapchat (@greatistsnap) and gave us a taste of her GreatistYou journey.

Meanwhile…

  • Brandon(@greatistbrandon)just discovered cauliflower rice, which lends itself to a handful of really delicious and healthy meals. (Pro tip: Try the honey-lime Sriracha glazed cauliflower wings. It’ll change the way you look at the vegetable.)
  • Adrienne(one half of team @greatistdanda)headed to NYSportsMed for a checkup and a little physical therapy—a good reminder for those who think they’re invincible. We don’t want anyone losing limbs this month; it’d be a huge bummer.
  • Jasmine(@greatistjasmine) is cycling her butt off and keeping her heart healthy. Despite the fact Jasmine says she fell off her bike twice, she still got back on and finished her workout. If you ever get frustrated, check out Jasmine’s awesome and inspirational sticky notes.
  • Finally, Greatist mentor Jessi (@greatistmentor) let us in on the fact that sometimes all you need to motivate yourself is a piping hot cup of coffee. Amen, Jessi. We, too, praise the almighty caffeine god.
