If you are incarcerated in their pretty little i-pod universe or any media player, they are presumably out of direct approach. Men know that portable radio and I-pod are one of the biggest hindrances when socializing in the gym. The question is how do you step forward to the chick you are targeting, the chick that is in a nut shell in her own little world of sound and clearly ready to lock the rest of you out? You can try saying something clever and if she saw your lips moving, she would usually take off the ear sets and ask what? However, her exasperation in having to do so is noticeable and this is an immediate negative posture which is not that easy to overcome.
