What an incredible company. I’m the owner of Reknighted: a physical and mental health coaching company, and I couldn’t recommend a certification provider any more. They are EXTREMELY efficient and professionals at what they do. Plus the level of integrity they run by is exceptional.

SPECIAL shout out to Mike from onfit, exceptional bloke and his genuine care is truly unparalleled to any professional I’ve seen. Top recommendation here.

I would highly recommend completing any course with Onfit College! Onfit was on top of everything from marking assessments to educational support. The teachers were friendly and very easy to get in contact with, they were very knowledgable and supportive. The course challenged me but with the support of the Onfit team it became easier, I felt the content taught me all new things and it was a massive help to my Fitness Instructor career. I will be completing future courses with Onfit for sure!

Onfit was fantastic in terms of their customer service and their approach to helping students. They were very prompt and keen in ensuring the best quality for assessment assistance. The student services was also fantastic where they were always willing to guide students in the right direction. I managed to secure a public health care AHA job with this qualification and knowledge provided. Highly recommend!!
