Probably the best deal in the region. I checked out a bunch of other gyms such as OrangeTheory (2…read morelocations), Gold's and Fitness Together in Georgetown, and Ambitious Athletics downtown closer to my work. I did my homework! These other gyms were all different versions of just okay for my needs, although I will note that Ambitious Athletics is well-run and a solid choice, and Fitness Together is lovely if you have big $$ and don't mind a perky trainer who blows smoke about your nonexistent skills, as though you were The Rock. Still, nothing really made me feel like I had found the place until I landed on Anytime Fitness.
Traffic and parking: Other posters have mentioned the parking problem, and it's true, so you should make another plan. I take Metro from my job downtown, and the gym is close enough to the Rosslyn stop for an easy walk. If you drive you could try doing Park and Ride from a different stop that has a parking lot.
Music: Gym, Uber, and coffee shop music has always been a sore spot for me, because I dislike most pop music lists (especially gack 80s) and most usually play it too loud. This gym keeps a pleasant club track without lyrics rolling, kind of like going to Ibiza or Mallorca but for regular people, and it doesn't trigger me as much as typical dreck coming out of overhead speaker these days. It's decent and I can ignore it, or use the rhythm to synch a machine workout. I may invest in some earbuds for my own music, but for now this is a-ok.
Trainers: I'm super picky about trainers because I want someone who is friendly but not nosy, and personable without oversharing. I also don't want to be praised all the time! Some people need a lot of high-fives and good-jobs, but that feels like BS to me. I just want to work with someone who knows what they are doing, be challenged, have some quiet chitchat that isn't too deep, and leave. I think the quality of the personal training is first rate here.
Equipment: It is all clean, functions well, and there is a variety between machine systems and free weights. Bathrooms and showers are clean. I almost always bring my own towel, but I forgot it once and their towels were fine (and free!).
Overall it was the best I found in the region, and although I wanted a spot in DC, I don't mind hopping on Metro to visit Virginia once in a while and go here. I hope this review helps them get more clients, because it seems quiet most times that I'm there. Obviously I don't want to have to wait for machines, either, but they could use a few more folks to ensure that it keeps running for many years to come.
