Super great place to train, everyone is friendly and respectful. The instructor is a very good teacher, I've learned so much in a short period of time along with my daughter who loves training here and he's great with the kids so I highly recommend this gym.

I'm impressed with the relaxed informal class structure at Sub-G. After training at a few schools over the course of a few years the non-traditional approach at Sub-G was very refreshing. This is a growth oriented learning space...
