It’s no secret that protein is essential to post-workout recovery. Resistance exercise breaks down muscle tissue and consuming protein immediately after a workout repairs and builds it.

Take a better look at the nutritional label—do you actually know what any of these ingredients are? If not, then it’s time to consider a smarter after-gym snack: buffalo, turkey and beef jerky.
