What a treat this was. I left my headphones at the house for the first time in probably 2 yrs. I got to admit it was kinda wierd but what the hell, I'll just work out anyways. To far to turn around and get them now. Let me tell you.... The headphones blairing in your ears really help a person zone out and focus on what you went there to do. I have never heard so much grunting, screaming, and just down right hollaring in my entire life. Does all this foolishness really help a person lift a weight?
