Star of the new "Get Extremely Ripped: Revved to the Max" DVD, Jari Love says that regularly lifting weights can help to build and preserve muscle mass, especially if you're looking to lose weight. In fact, research shows that as you lose weight, a portion of each pound you lose comes from muscle, which slows your metabolic rate. A recent study found that when people cycled for 30 minutes a day, they lost three pounds of fat and a half-pound of muscle, whereas those who cycled for 15 minutes and weight trained for 15 minutes lost 10 pounds of fat and gained two pounds of muscle, she says. The weight-lifting group also increased their metabolic rate, allowing them to burn an additional seven calories per pound per day.
"While cardio is important for maintaining cardiovascular health, maximum benefits will come from cardio plus weight training to build lean muscle that burns more calories and fat," Love says.
