Keeping Fit: Cardio with Andrea Metcalf

Strong bones are the foundation of strong bodies, and strength training is an ideal way to build bone and muscle mass. It also increases your metabolism so you burn calories all day--keeping you lean, firm, and looking terrific.

Ten 5-minute exercise blasts allow you to customize the practice to your needs. Start with a few segments and mix and match them as you grow stronger--you’ll be doing the full program in no time.

Each mini workout incorporates straightforward sculpting moves that target the upper and lower body and the midsection for an efficient, total-body tone up. So pick up some light hand weights and get started!
