I'm just starting to try to find the time to exercise on my lunch hour. What cardio workout tends to blast the most calories?
Stop thinking about what you're doing and instead focus on how hard you are doing it! You can run for hours at a light to moderate intensity and not burn nearly the amount of calories you might in a 45-minute cycling class or run on the treadmill where you change your intensity every 5 minutes. I say choose your favorite cardio exercise (dancing, running, walking, kickboxing) and vary your intensity throughout your workout for the most efficient and best results
