  • I have been coming here since summer 2017. I got pregnant and workout to almost until the end of my pregnancy. Then, 6 month latter after my delivery, I came back. I would not change 9round for any other gym. I like the set up and workouts. The workouts are never the same; in 30 min they suck the hell out of you. It is easy and convenient, and now that I am a mother I need something effective and quick. I highly recommend this gym.
