Why outdoor training?

Nature is your gym.

Training in the fresh air has countless positive effects on health, mood and wellbeing. You will notice these five points after the first sessions.

  • Fresh air
  • More vitamin D
  • Stronger immune system
  • Healthier cardiovascular system
  • More positive mood

Outside all year round. With a good warm-up, the right clothing and a lit training location, training is possible in winter without any problems. It is also important for your health to spend as much time as possible in the fresh air.

In bad weather or other conditions, training can also take place in a gym – or in the Petrispark, which is covered.
