I wish I knew why my wrist was popping out, must be too much of a strain I guess. Made doing some things today suck a little, but I got through it

That's great that you joined a gym! If they told you not to workout before your assesment, I'd listen, you can always do it later, maybe get it done after the assesment Good luck and pay attention to everything they show you. Ask them questions if you need to on how to work the equipment.
