30 Minutes to Fitness: Start Here

Two well-structured programs for anyone who's just starting to work out or who “fell off the fitness wagon.” Kelly combines easy-to-follow exercises with lots of intensity options and sincere encouragement (“just 30 minutes you can do this”). The first program begins with a varied mix of athletic-style cardio favorites (always offering a “base” move if you get tired or distracted). That's followed by an aero/tone segment that builds muscle as it burns fat. The toning workout features alternating sets of proven body-sculpting classics (e.g. curls lunges push-ups). It starts with standing routines and ends with floorwork. Requires 2 to 5 lb. dumbbells.
