Sometimes I think we should just hire women to fuck us over and piss us off on workout days. Nothing like a dumb bitch to fill us with a bit of rage to tear it up in the gym.
Ever get weird looks because it's obvious you're a pissed-off pumper? I was listening to Megadeth and going to town last night with curls, then beat the shit out of myself on a Precore. I usually keep it at around 130-140 strides per minute, but I cranked up the intensity and went at 180 for five minutes - I could barely walk when I was done. If you use 'em right, you'll get an awesome burn from those things..
