who we are

About Us

our philosophy

Giving you an unforgettable training experience

There was a time when movement was naturally part of everyday life. Working out was only needed for those who participated in competitive sport. This changed. Our modern lifestyle does not require a lot of movement. Modern people sit too much and move too little.  Over consumption of processed fast foods, lack of movement and high stress levels, are at the root of many lifestyle diseases. Health is wealth, but unfortunately most people only realise that when they lost their precious health. Our hectic schedules are greatly to blame. How do you fit exercise and healthy eating into busy day?

We at Fit@Nature do not want to be spectators, waving at an unhealthy population struggling through their busy days. We know we can help. We took action. We created a unique exercise experience with real results.

We believe that a training facility where you can relax in a natural environment, get a proper workout in a short period of time and have the option to order healthy food to take home, will provide a perfect solution to modern day challenges.

For the first time in my adult life I love training! Thank you for helping me and encourging me all the way. I lost 8kg since I started 7 months ago and feel great!

Ek oefen nou al 5 maande saam met Retha en haar span by die HIIT klase. Die HIIT klasse is vir my baie lekker. Ek sien uit daarna om te gaan. Ek het nooit vir een oomblik nog in my hele lewe gedink ek gaan die tipe outjie wees wat van oefen hou nie. Buiten vir die feit dat ek die klasse vreeslik geniet, voel ek vir die eerste keer in baie jare goed oor myself. Ek sien elke week hoe ek verbeter en ek het meer energie.
