I keep seeing a commercial and it bothers me a lot. It's a commercial for some state college that is advertising how you can go to there school to become a personal trainer. You don't need to go to a school and pay them thousands of dollars to become a personal trainer! That school is robbing people of their money by misleading people to think that they need to pay a few grand in education to become a personal trainer. If you are interested in being a personal trainer, you should buy a book that teaches you about it, read it, implement it and then go take a test to become certified. There are many different certifications that will all give you title of personal trainer and most gyms don't care which one you get so long as you have one. Some of the best known and most accepted certifications are ACSM and NASM. Every gym accepts those 2 personal training certifications. ACSM deals a lot more on the physiology of the human body than on actual workout routines and the test is probably the hardest to pass of all the personal trainer certifications.
It's amazing how misleading and deceiving an organization can be just so they can make some money. Don't be deceived by schools offering fake degrees that they made up so that they can earn some extra money from students.
