I've done no cardio for the past 3 weeks, and lost 8 pounds. Explain that! All you need is a solid diet, and high intensity training. If you guys want to waste your time doing 3-4 hours of cardio per week, go ahead. Ever seen a difference between a distance runner and a sprinter? Which one would you rather look like? I want to look like a lean, muscular sprinter, not a weak, skinny jogger.
