When I’m not at my computer writing about fashion, there's a good chance I'm breaking a sweat somewhere. Whether I'm out on a run or flexing in yoga class, I consider fitness an important part of my weekly routine. As a result, I’ve had the chance to road test (or sweat test, maybe?) lots of different leggings—it's my job after all. Some, like Nike, are great technical styles for a long run, whereas brands like Outdoor Voices are a favorite for when I’m headed to yoga. But it may surprise you to find that one of my favorite pairs of leggings costs just $30 and comes from Old Navy. Technical apparel can oftentimes be pricey, but Old Navy’s activewear isn’t just super affordable, it holds up during tough workouts too.
