I recently started receiving ads from a school called the National Personal Training Institute, telling me how I can get into shape and train for a career as a personal trainer all at the same time. The cost for a 1-2 year period is $5900. But I have a friend who is already a trainer who says that the test is something you can just study for and pass for a lot less money, and I can still get my certification. Has anybody out there heard of this school? And have any trainers out there ever gone to a place like this to get certified?
