I think it's a bad idea to allow personal trainers to practice acupuncture.  Acupuncture is a 4000 year old medical tradition.  Western medicine, by contrast, is only about 300 years old.  We don't let personal trainers perform surgeries, and we shouldn't let them do acupuncture.  Also, acupuncturists go through years of training and board certification.  Allowing personal trainers (or anyone) to usurp all that training is a bad precedent.
