It's no secret that Selena Gomez and Justin Bieber have been working hard at their relationship, but that's not the only thing they're working on! Since getting back together, the couple has also been spending a lot of time working towards a healthier lifestyle. Selena is often spotted cheering Justin on from the sidelines at his hockey games, but now the two found an activity they could enjoy together. Fresh off a vacay, Justin and Selena were seen leaving a hot yoga class together Wednesday afternoon. By the looks of this photo, that was one intense work out that I want no part of.
