Great community gym!  I started maybe 3 years ago but was super-reluctant to start.  After finally getting myself to try it out, I found that the coaches were super-supportive and helped me scale where I need and push me where I need.  The other members are super-welcoming and supportive as well.  I haven’t been to a gym before where everyone roots each other on.  Can’t say enough positive things about the gym, the coaches and the members.
