Loved the online format and support

I found the online format, support and materials at OnFit very user friendly, informative and clear. I am really enjoying the practical element. I feel like I am literally pinching myself every day. I thank my OnFit tutor…, again for all of her help and support and encouragement. I could not have done it without her. Just being able to talk out some of the questions made me feel like I was in a tutorial group!”

The best aspects were being able to learn in a comfortable environment, in a flexible manner. Reliable teachers – able to call as soon as I had a problem and the assistance they offered was brilliant!

Cert III & Online
Some fitness courses are fast tracked and only briefly cover certain skills, however I feel Onfit is very thorough and offer so much support! Keep up the great work!
Tim K.
Cert IV Online Graduate
Choosing Onfit Training College was the right choice. When I shopped around for which online PT course I wanted to do, I looked at a lot! I didn’t rush into deciding either. Many of the course providers I contacted had pushy salespersons trying to offer “special deals” only valid that day. Not Onfit. I felt they were genuine and truly wanted the best for me too. Their online course material is very user friendly and their free app for the Ipad means I can have my study material anywhere, anytime. No need for a wi-fi connection. I have been able to study sitting in the car waiting for the kids at music, waiting at a doctor’s appointment (you know they are never on time). Any spare time, I read the next topic. I have received the best support from my tutor, Jo, in my Cert III. She has been very informative, provided feedback and helped with those questions that I needed a little more understanding. If you want a reliable, informative and supportive course provider – choose Onfit Training College.
