Hi Guys
I would agree 1000% with Laura on this one. Having worked in the Fitness Industry for many years I am very aware of quite a few instructors teaching classes who do not have relevant qualifications. It can potentially be very dangerous on many levels. I am and have been treating quite a few clients as a result of poor quality instruction in classes.
Key piece of advise is to ask to see their qualification, if they have it they will be more than willing to show it to you.
