While many Americans battle obesity and their effects such as cardiovascular disease and diabetes, there are many choosing to prevent those conditions by exercising regularly.

"The Centers for Disease Control recently estimated that only 20% of us get the recommended amount of daily exercise," Dr. Brett Osborn, told us. The physician is the author of Get Serious, A Neurosurgeon's Guide to Optimal Health and Fitness.

Cardio is better than lifting. For all you chronic dieters and cardio enthusiasts out there trying to shed fat, the right strength-training program can boost your metabolism and help burn off more fat. "By increasing lean muscle mass, you will increase your basal metabolic rate, BMR," Obborn said "Activated, contracting muscles are the body's furnace. Excessive cardio and dieting can eat muscle tissue away, compromising this furnace."
