Since 15.03.2018 we offer in cooperation with the TK a weekly back course with us in the company. On 16.09.2021, we already started the fourth round, of course in compliance with the usual Corona safety regulations and the three G-rule: Vaccinated, Recovered or Tested! Every Thursday at 16:40 to 17:30 pm our training room becomes a gym. Also our SE-duck Selly has a lot of fun with it!
