Exercise Myth: To Burn the Most Calories, Focus on Cardio

The reality: Both weight training and cardio burn calories, but lifting weights boosts your metabolism for up to 24 hours after you work out, says exercise physiologist Irv Rubenstein. Depending on the intensity of your workout and your fitness level, your body will continue to consume additional oxygen, and therefore burn calories, as it returns to its pre-exercise state. For best results do intervals -- combinations of cardio and weight training -- on one or two days, along with traditional cardio the rest of the week.
