I love the arrival of Spring, so April is one of my favorite times of year. It makes total sense that Earth Day falls during April, too. We all get to head outdoors for our workouts and celebrate everything that the planet has to offer. Our April picks are all about being fit, but in the most responsible way. You'll find gear that is made in sustainable ways using responsible materials, and it's my hope that you'll even be inspired to plant a tree or two!
