"Then you’re at the gym working out, you probably don’t want to hear the huffing and puffing of the sweaty guy (or gal) next to you. That’s part of the reason why you might bring along your iPod or iPhone along with you, bobbing your head to the latest Smashing Pumpkins release or pumping your fist to the adrenaline-fueled tunes of Journey. Whatever your musical interests, you want to keep your mind focused on the music and not the grunts of the other gym rats."
