It’s January, meaning we all just made New Year’s fitness resolutions revolving around health and wellness. To that end: We linked up with real women to help them find new favorite sports bras that would help propel them through their workouts. They put some of our merchants’ picks through their paces at the gym, in the dance studio and on the trail, then reported back. Here, in part one of our two-part series, is what they found—so you can find new ways to power through this year, too.
