My experience at MMISS was nothing short of amazing! Studying under Mark and his team, I knew I was learning from industry professionals, past and present, who set the standard. The MMISS educators are second-to-none; their knowledge and support combined with world-class educational resources raise the bar for fitness courses.

After discussions with Mark McGaw and his team, I chose MMISS due to its solid 25+ year reputation as a fitness education provider, and MMISS pioneered online fitness course delivery in Australia. Through my learning experiences with MMISS, and subsequent experience as a practicing personal trainer in Australia, I feel very confident in doing so. Thanks Mark!!

Mark is an amazing fitness tutor and I am grateful to learn from someone that is successful in the fitness and sports industry.  He knows what he is talking about and explains everything in great detail.  After doing my certificate 3 & 4, I have been confident in entering the fitness workforce as a personal trainer immediately.

Price ,efficiency and convenience are the greatest advantages of the MMISS. For the same certificate you can hardly find a lower price than the MMISS. The courses can be all done online without any time restriction (deadline), which may be the most convenient and comfortable choice under current COVID 19 situation. Every time I finish a small block, I get the feedback in a very short time from the assessor, which is very efficient. Thanks for Mark and the assessor Steven for their excellent work.

I became interested in fitness when I was around 12 after watching Rocky, 1, 2 and 3, this being in a 6 hour cinema marathon – from then on I was hooked on bodybuilding – my first body building show was at 14 and after winning Junior Mr UK, I was spotted in a bodybuilding magazine and head hunted for Gladiators and won the ultimate gladiator competition. I chose MMISS due to its reputation, for being an in the trenches, science based, certification. This gave me an edge in fitness as both competitor and the running of my business.

James CrossleyJames Crossley

As a National Level competitive athlete, I was no novice to physical training and nutrition. However, Mark’s hands on approach to teaching core concepts helped me take my own training to a whole new level. More importantly, Mark made a determined effort to impart as much of his personal wealth of knowledge and experience from the Fitness Industry onto me so I could be well placed to become the most professional and well-rounded competitive personal trainer market. With Mark in your corner, you can have the confidence you have the best tools in the business to give your future clients the professional service they deserve.
