I want to enter the field of fitness and bocome a personal trainer. I was just wondering if the real successful ones have been to university or if they only completed certificates at Tafe (etc) and gained experience once at work?
In other words would i be more successful if i went to uni or tafe?
Please help.

Go to a University and get a degree in physical fitness.
You will have better credibility PLUS you will earn much more money.
