Hey guys, I'm looking for somewhere I can swim/work out, the only thing I'd only have nights available, after 10 or so.

One of my friends said a gym might be the best bet since some of them are open 24/7.

So can anyone recommend any places. I live in NW OKC near NW Expressway.

Aspen on NW Expressway and Rockwell (I think or maybe a mile east or west) has a pool and is open 24 hours now.
