After trying MOSSA workouts back in 2011, I decided to become a certified MOSSA instructor, which turned out to be one of the best career choices that I have ever made.
Being trained by MOSSA experts makes me feel so honored and lucky. Not only did they teach me proper techniques and execution, but they also guided me step by step on how to pass them on safely to my clients. Their support is continuous and guaranteed.
Being on stage motivating people is a huge responsibility and a great blessing at the same time. Apart from extra income, helping people reach their fitness goals is the greatest reward. Their satisfaction and smiling faces at the end of the class are what makes this investment totally worth it!

MOSSA program training is truly unique. Thanks to it, I have developed and grown immensely as a group fitness instructor.
In my experience, the investment is minimal and pays for itself very quickly.
As for the support I received, absolutely. I felt supported the entire time, and even now, I know that I am not alone and that I have someone backing me up at any given moment.
Honestly, MOSSA programs have helped me tremendously to profit from group fitness and to keep both the participants and myself highly engaged. On top of that, I continue to develop with every single new release; I never have to wonder what I'm going to teach, and I am always fully prepared for my class.

You can access the training on your computer, tablet, or smartphone, giving you the flexibility to complete it whenever it suits your schedule.
How long do I have to complete the online training?
You have 30 days from the date of enrollment to complete your online training. Most courses include approximately 10 hours of content, and participants typically finish anywhere from 2 days to 2–3 weeks, depending on their schedule. If you need more time, you can purchase a 30-day Online Training Extension for €30.
Can I start teaching after completing the online training?
Yes. Once you complete your online training, you may begin teaching classes immediately. However, you must submit your Assessment Video within 90 days of completing the training. The video should be a recording of a regular class and can be submitted electronically (e.g. via WeTransfer or a Google Drive link) to [email protected].
Improtant Note: If your Assessment Video’s gets a PASS then you will receive your ASSESSMENT CERTIFICATE OF COMPLETION certifying you as a MOSSA Instructor in the specific program.
If you do not pass your first assessment you will receive a RESUBMIT, and you have another 30 days to resubmit a video. If you do not pass assessment again, you can resubmit one more video.

If you have passed the 90-day due date, you are no longer allowed to teach classes. However, we realize that you have to teach to participants for your assessment video, so, in this situation, you can gather some participants during an unscheduled time in the group fitness room at your facility to film your assessment video. Once you pass assessment, you can start teaching classes normally again.
