PHUAG:
asking if anyone has injuries or is pregnant
In Australia this is actually a very grey area at the moment. There is no official advice on whether instructors should ask if there are injuries or pregnancies in the class. This has been mentioned more than once on various official courses I have been on, and the general consensus is that they do not know which to advise an instructor does until such a time where the outcome of a court case makes it clear. This of course, is making everyone nervous, including the actual fitness education organisations.
By asking if there are any pregnancies or injuries in the class could, in the court of law, leave you liable for that person during your class. On the other hand, not asking for injuries could also leave you liable for failing to provide adequate advice and options during the class.
Basically the official advice being handed out at the moment during Cert 3/4 and group exercise courses is that, be very very careful about what you do or don't say before the class and that you have to make a decision for yourself on where you prefer to place your risks.
I used to solve this problem myself by saying something more vague like "if there's anything you need to tell me, please let me know as I come around and collect your ticket".
