ML, have you been asked to fill in any forms yet? If not, have you been given an appointment with an instructor for fitness assessment and program design? This would be the person to tell.

I'm sure you're aware that in the gym, there are multiple instructors and even more patrons. It may be difficult for them to keep it in mind all the time. BUT, if anything happened to you, they should pull your info and have it out for when an ambulance arrived. You could ask them to put it in red at the top of your program if you feel comfortable with other patrons seeing that.

Do you wear a medic alert bracelet or anything?

Out of curiosity, where do you live? When I was at the gym today, there was two separate people signing up - how cool would it be if you went to my gym?! Because, of course, my gym is the only one in the whole WORLD who had any new clients today!
