Core stability

Core stability is strength training for your entire body, creating a good and stable position in the water. You also enjoy the benefits of core stability in running, leading to a well-trained body, strong legs and a good attitude. The exercises are specifically aimed at triathletes. The gym is only 1 km from the Ir. Ottenbad, so it is ideal to combine two training sessions on an evening.
Members of The Triotters can follow these courses for 20 euros per year. Non-members pay 36 euros.

  • Monday nights from September 15 till April 15 at 20:00 to 21:15 hours.
  • Address: Grebbeberglaan 55-a, Eindhoven. The name of the location is 'Gymzaal Grebbeberglaan'.
