Hilarious!!!!!!!!!!!!!!Everyone says the "pump" is worthless but ask the pros what they think. I used to be trained by Larry Scott. Larry says that a training session that does not result in a good "pump" is a wasted session. Larry subscribes to the "pump and go" philosophy. You workout out until you get the maximum pump and then quit. Going beyond this point is counterproductive. Arnold says the "pump" is essential to good gains. He also says that the "pump" is better than sex. The big boys believe that the "pump" is essential. I believe they know what they are talking about.
