Sarah Olive Bergeson is an AFAA certified group exercise instructor, personal trainer, writer, workout lover, clean eater, and mom. She lives in Los Angeles with her husband and her two busy little boys. You can usually find her crouched on the floor looking for lost Transformers under the couch or staring weirdly off into the distance with bitchy resting face, even though she’s not mad. She loves David Bowie and when things are very organized. You can see more of her articles and workouts at Organic Authority.
