Getting Qualified

By Qualified, you need to be REPS level 3 qualified if you want to work as a personal trainer in the UK.  http://www.exerciseregister.org/ will provide you with more of the framework than I can. But you'll need to complete level 2 in gym instruction or exercise to music and then move on to level 3.  You can expect to pay between £2000 and £4000, you need to ensure that the course gets you onto the REPS register.  One of the lower priced ones in the UK that provides this are Discovery Learning, you can see them here  http://www.discovery.uk.com/.

Alternatively, if you are of a certain demographic, you could qualify for funded learning.  Here is some more info on this http://www.lifetimehf.co.uk/for-you/work-based-learning or you can look into getting a career development loan, you can see more here http://www.direct.gov.uk/en/EducationAndLearning/AdultLearning/FinancialHelpForAdultLearners/CareerDevelopmentLoans/index.htm
