I'm doing my Cert III in fitness at the moment. Have managed to get through it with high distinctions and distinctions so far. Waiting on results from my most recent assessment before I get on to my last 2. Once I'm done I'll be a qualified fitness instructor. Will likely go on to do cert iv and my diploma. The great thing is that since I know so much already from my own experience, I am flying through it and my assessors are very impressed with some of my answers to the questions.
I run an outdoor fitness group on Saturday mornings (which I've put on hold now until I've finished with my comps) and it would be good to continue that with some more people moving forward (and possibly actually getting paid for it). I wouldn't ever want to be a PT full time. I love my job too much to leave. It would be good to do on the side though.
