Being Fickle About Your Workouts Pays Off

Bone loss, back pain, high cholesterol . . . very different problems. But there's a single solution. Abandon the same old workout routine.

Your mind isn't the only thing that's tired of the treadmill, bored with the bike, or completely out-of-love with the elliptical. Your body might not be getting everything it wants, either.

Research shows that the broader the variety of exercises you do, the more health benefits you get. The triple reward for consistently mixing it up: stronger bones, a limber (and ouch-free) back, and a healthier cholesterol profile. (And let's not forget a higher chance of not burning out on one particular workout.)

When women who went through menopause early combined a range of physical activities -- from strength training to jumping rope -- the results were clear: Broadening their fitness menus expanded their physical benefits. After 2 years of doing cross-training workouts at varying speeds and intensities, the women had increased their bone mass, boosted their muscle strength, reduced their back pain, and improved their cholesterol profiles.

Mix strength and cardio workouts into your week, and try these strategies to keep things fresh:

• Add intervals -- short bursts of increased intensity -- to a workout.
• Explore new equipment or classes. Or take up a new sport, such as racquetball or ballroom dancing.
• Try combo classes. Many water workouts blend swimming and strength training; yogalates combines yoga and Pilates.
• Work out with a buddy. Get the benefits and joys of socializing (and maybe even enjoy a little friendly competition) while you work out.
