Awesome gym! I was visiting from out of town and needed a place to workout. TJ and his coaches were all super welcoming and helpful. Every kind of equipment you need for either Open Gym, personal training or group.

Thank you, TJ, and his friendly staff for creating such a welcoming place to work out. I always feel a bit intimidated going to a new gym but TJ has developed a month-long plan to help new-comers (such as myself) learn and grow. Regardless of fitness level, I highly recommend TJ's Gym.
