Welcome to the NatGym®

The Natural Gym, (NatGym) is a unique form of outdoor physical training session run by Terra Incognita Fitness (UK).  We don’t use any equipment and we don’t have a gym apart from the countryside with its natural obstacles and terrain.

Whether you’re training for an obstacle race such as Tough Mudder or Spartan, simply want to get out of the conventional gym and learn new skills or want to spend more time in the great outdoors, this is for you.

We run NatGym sessions in all weather, by day and even by night.  The human eye has evolved to work in low light conditions yet in the modern world we rarely use it’s full potential.  When was the last time you worked out in the dark?  It brings you closer to nature and makes you more alert and aware of your surroundings.  We also believe in the importance of being able to operate safely and confidently in all weather conditions.  Anyone can workout in an air-conditioned or heated gym but it’s an unhealthy environment and can be expensive.  It takes real mental strength to operate in bad weather and maintain your effectiveness so we train that too.

If you spend most of the day stuck in an office or travelling why workout in yet another enclosed, indoor location?  Training in the NatGym provides far more opportunities to de-stress, learn more about your environment, yourself and above all improve your mental and physical health.


Where we work:

We can operate anywhere given enough notice, although typically you’ll find us training in Whippendell Wood or at our dedicated NatGym® site at the beautiful Hunton Park hotel near Watford, Hertfordshire. 



NatGym® sessions can be run on a private/one to one basis or for groups/team building/corporate activities.   Planning on organising a team for an obstacle race event?  Why not train together too in the NatGym®.  If you’re thinking of running a retreat why not get us involved, we’d add a whole new dimension. Feel free to explore our site and if you want to know more send us an email via the contact form or call: 07398 823637
