Staying active has been my key to aging successfully. Regular exercise not only burns calories, it also dramatically improves both body and brain functions. My Fit & Strong DVD includes two 25-minute workouts that will burn fat, tone and shape every major muscle group and strengthen your core. Make a habit of doing these workouts and you'll look and feel your best. Level 1: Start with a gentle warm-up to get your body ready for action. We'll work all major muscle groups, including upper body, lower body and the core, then end with a soothing cooldown. Level 2: After an essential warm-up, we'll tone and tighten all major muscle groups while adding moves to improve flexibility and balance. End with a cooldown and gentle stretch.
