Well, it's important to note that Arnold wasn't training naturally either. That will definately speed up your recovery time. Many times people tend to do ab work with a less than intense focus. You don't see anyone pushing and grunting on their abs as they would on a squat. This is a mistake. If you want to grow any bodypart I challenge you to train full tilt...even your abs. But, I know you're looking for other opinions, so hopefully some others will chime in for you.
