A section from the Which? magazine investigation into Personal Trainers:
"We are constantly being advised to take more exercise. Millions of us have put our wellbeing in the hands of gym instructors we assume are properly qualified. But our research shows some aren’t adequately trained. It is also worrying that anyone can set up a gym and run it without qualifications.
While the register of exercise professionals is laudable, it is only voluntary - so it will inevitably only attract those who have gone through the correct channels. We think registration should be mandatory and gyms should be regularly assessed, with penalties imposed if they’re found lacking.
The onus shouldn’t be on customers to check up on staff. But our research shows you should never take an instructor’s advice without questioning his or her qualifications first. "
