It is another Sunday at Industrial Athletics, the Home of CrossFit Alloy. Â Only, this Sunday, we are moving walls. Â We will all be doing construction, but if you really want to come to Open Gym, you may. Â Got something in mind you want to do? Â Open Gym is the place for you. Â Tired of coaches telling you want to do? Â Open Gym is the place for you. Â Maybe you need to make up those Fundamentals Classes. Â Come to Open Gym.
