Why Study with Onfit?
  • Flexible, Quality Online Courses
  • Extensive Support from our Expert Team
  • Industry Approved Theoretical Knowledge
  • Relevant Fitness Business Skills

Some fitness courses are fast tracked and only briefly cover certain skills, however I feel Onfit is very thorough and offer so much support! 

Tim K
Certificate IV in Fitness 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.

If you want a reliable, informative and supportive course provider – choose Onfit Training College.

Kathryn Y
Certificate III in Fitness Graduate

The best aspects [of studying with Onfit] 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! 

Taylor R
Certificate III & IV in Fitness Graduate

“After graduating from Onfit I have used my qualifications to start my own personal training business, at Anytime Fitness Toombul, which gave me the flexibility to pursue my passion to play Rugby Union at an elite level.

Since then I have opened a boutique performance training studio, Maxxfit Performance Studio, in Fortitude Valley and my own Anytime Fitness 24hr fitness centre in Kallangur on the northside of Brisbane.

I have been able to achieve these things in the industry from hard work and the knowledge I received from the courses with Onfit. If you’re passionate about helping people transform their lives, then studying with Onfit is for you.”

Lachlan C
Certificate III & IV in Fitness Graduate

“I’m loving studying with Onfit. Everyone is so helpful & friendly and if I ring and ask a question I always leave the conversation feeling confident. I’ve learnt so much.”
