This week, greatists from around the web made some killer choices for their fitness, health, and happiness. We went straight to the source — Twitter and Facebook — for some awesome #imagreatist posts! From home-workouts to fruit-infused water, standing desks to Tough Mudders, we're inspired by all the small choices that are making a huge difference.
