Keeping Fit: Strength 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.

Strengthen the most important muscle in your body—the heart—with this simple, fun cardio workout. You’ll burn calories and fat, increase lung capacity, control your weight, and add energy to your day.

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 is full of moves that get the heart pumping but are easy to perform and modify. You’ll grapevine, jab, squat, and kick your way to a strong and healthy body. So lace up your sneakers and get started!
