Did You Know Doing Only Cardio Slows Your Metabolism?
If losing weight conjures up visions of hours of mindless treadmill workouts, you’re in for a pleasant surprise. It’s not an efficient way to lose weight, says Robert S. Herbst, personal trainer, coach and powerlifter. “When you just do cardio, your body slows down your metabolism to conserve energy (calories).” Instead, Herbst recommends a combination of interval training (alternating bouts of high and low intensity) and weight training. “These activities rev the metabolism because the body spends calories to repair and build new muscle as it recuperates from exercise,” he says. The new muscle also burns more calories at rest, boosting your metabolism all day long.Source
