He's worked with huge A-list clients like Jennifer Lopez, Ryan Seacrest and Sofia Vergara, so what's celeb trainer, Jay Cardiello's pick for a post-workout bite? A bagel and jelly! He tells Men's Health, "The bagel itself is an excellent source of dense carbohydrates to help refuel muscles for recovery." Jay also tells the mag you shouldn't feel guilty gulping down a glass of chocolate milk! Another huge fan of chocolate milk is WNBA star, Skylar Diggins! She says chocolate milk is the best thing post-workout because it gives you recovery and helps refuel muscles. Who wouldn't be motivated to workout if you knew something so sweet was waiting at the finish line!
