If you’re AFAA certified…you will find over 25 “Personal Fitness Trainer Forms, Questionnaires, PAR-Q’s , Liability and Assessment Forms” in your AFAA book (first edition, 2006, revised 2007) in the Appendix C…pages 418 thru 456.
I Hope this Helps!
Nothing is too probing when you keep everything confidential; the information will help you help the client. The clients do not have to answer what they are not comfortable with, anyway.
ACE text books also have forms. Whoever certified you should have forms for you to use, as well.
I just did a quick Google search and was surprised how many I found. All I entered was ‘personal training health questionnaire’. Here is one example which is very similar to the form that I am using. http://www.evolutioniwc.com/images/pdf/health.pdf. You will also see sample physician approval forms.
Hope this helps.
