Why it's a star: Celebrity trainer Jeanette Jenkins and her crew, including Kelly Rowland, Grammy winning R&B singer and judge on The X Factor in the UK, teach you fun and challenging exercises that will leave your ab muscles burning. You've seen some of these moves before (bicycle crunches, roll-ups and planks), but the nonstop pace, focus on lower back pain-prevention and the sprinkling of innovative exercises makes this DVD worth an encore in your sweat schedule. You'll feel the burn throughout your core the next day!
Bonus: You can join the #SexyAbsChallenge on Twitter with @KELLYROWLAND and @JeanetteJenkins now for five weeks of healthy tips, meals and motivation as Kelly gets ready for the Grammy Awards in February. She's nominated for her song "Motivation!"
