Challenge yourself with one of your hardest workouts yet from Jeanette Jenkins of The Hollywood Trainer Club. With cardio-intensive exercises that will leave you breathless and toning intervals that will quickly have your muscles burning, you'll need to dig deep to stick with this workout. You're going to be constantly moving, so it's important to have a good source of protein, like a think! protein bar, packed with 20 grams of protein to aid muscle recovery.
