If you know of a fitness center in N. Arlington/EFC

[zumbamama]

either a gym, community center or condo/apt. building that has a fitness center...I am looking for a 6am class to teach, once or twice a week. I've contacted several places already, but they all have Bootcamp everyday at that hour. So just putting it out there in case anyone knows of a place where there may be interest in starting up a Sunrise Zumba class. Gracias!
