One of the many awesome things about teaching Body Challenge is that each week I get to comb through all my favorite tunes and put together a 45-60 minute mix of movement inspiring music. I try to combine the best of what's new with my favorite vintage tracks so there's something for everyone. I'm a personal trainer, not a DJ. But I have to tell you, there's an art and science to mixology that I find rewarding. So if your playlist is leaving your workouts lackluster, try one of these 10 mixes and see if you get inspired.
