Lets face it, most Olympic 100meter to 200 meter runners would smoke most state level bodybuilders if they decided to step on stage...Short High Intensity cardio obviously works...Why don't you hear about it in the novice to lower level bodybuilders who have other things going on in their lives who don't have the time for 2 hrs of low intensity cardio? Are these people really that insecure that they believe it will take too much muscle away from their precise 175 pound body?
