Testimonials

Imagen Mélanie Van Den Steen

"Radical Fitness is just the best!!! There are so many different programs tailored to everyone’s preferences. The classes always go by too fast because they’re so great, with super energizing music every time... I wouldn’t switch to anything else for the world ❤️"

Imagen Bernard Hakir

Imagen FIT GIRLS

Imagen Teresa Walkinshaw (Group Fitness Instructor)

Hi everyone, my name is Teresa 🐯

I absolutely love every thing about Radical Fitness ❤

Ubound is my absolute favourite high energy cardio. The music sets the pace to match the beat in Ubound. I love that the choreography isn’t long and complicated! 2 columns!! It’s so easy to remember. The moves and combinations are awesome, you get that high intensity interval cardio that really works for everyone, with lots of positive experiences!

Power is exactly what I would want in a bar class. The beat drives the rhythm for execution, that elevates and motivates you more. Some of the tempo allows you to create depth in the movements. I love that you can either choose to increase your resistance or go endurance or power cardio! My favourite thing about Power is the super series where you get to train a muscle group over 3 tracks 💪 The formats are innovative and I love that it is different.

I love the cutting edge of new training with Radical Fitness, it’s also the latest in fun training and there is something for everyone in each program.

The teaching in each certification is amazing and really informative.

I like to think the experience I give to the members is positive, high energy and inspired coaching! Not being bias but Radical Fitness make the best programs.

Proud to be a Radical Trainer ❤

Imagen Effie Fonseca (Group Fitness Instructor)

Hey all, my name is Effie and Radical Fitness changed my life.

I have been an instructor for a very long time and group fitness is my passion, I love the fitness industry... then along came Radical Fitness and it was a game changer. The certifications were so informative I just could not wait to teach.

These programs changed me as an instructor, they made me stronger, fitter, more confident and more passionate then ever before. Top ride is my program, I had taught cycle BUT Top Ride was the Gold class. The program has different formats, it pushes you to a limit you think you could never get too.

The bike room is always full, as the program challenged everyone. Needless to say, this was my new superhero and all the members love it. Top Ride offers climb day, full day and race day and it is so dynamic that you burn well over 800 calories.

If you have time restraint and can only fit in a quick class well this will cover everything for you, not to mention great stress release. Try it and discover the benefits for yourself.

Imagen Aimee Scott (Gym owner and Group Fitness Instructor)

Thank you Melissa and the team for all your help bringing Radical classes to Aimz Fitness!

From certifications, on-going training and launching classes we have felt supported the whole way. I would highly recommend Radical Fitness.

Imagen Roxanne Kelly (Gym owner and Group Fitness Instructor)

I have been teaching Radical group fitness classes for many years now and I love the variety of music that RF uses. The programs are all professionally and cleverly choreographed.

It is hard to pick a favourite programme because they are all so good and offer such a variety of classes that offer something to suit everyone.

Oxigeno is loved by my older attendees as they feel so good when they leave the class.

Power is very popular with runners as it helps their strength enabling improved performance. Top Ride supports anyone wanting to get into fitness as they can do it at their own pace and also extends the fittest person at the same time. RF is the best!!
