Wanna talk to a lady i see everyday at a gym. how to break the ice?

i'm doing summer at my college, and i go to the gym everyday. at the gym i always see this girl, who is a suitemate of a female friend of mine (starting from here i will call the girl of my interest j). J and i have never talked, but i know her name. i think J looks really gorgeous. she's about 5'4" and has a pair of eyes that literally hypnotizes me. i look at her quite often (i don't stare tho), and when our eyes meet i just look away. i am dying to talk to j, but i just don't get an opportunity. if i just go up to her and start talkin, it will be so awkward. i have to either 1) wait till j and j's suitemate throw a party or 2) wait till my friend C, who knows J, visits and introduces me to her. According to my friend C, J is a "waste of a cute face and a nice body, but a nice girl". He said J is the most boring/awkward/silent person he's met but i would like to get to know her. she may be friendly towards me. who knows? what would you do if you were me?
