Working out is tedious enough without having to shuffle though thousands of songs for your running mix. But thanks to Run Tracks, that's a thing of the past. Not only does the blog provide you with tons of pumped up songs for your workout, it categorizes them by genre, and even what type of routine you're doing (lifting, sprinting, warm-up, etc). Now you have no excuse for not getting in shape.
