Not necessarily. You decide whether a membership, a day pass booking or a single course booking with one of the more than 46,000 sports providers in Germany best suits your needs.
The great thing about MySports corporate sports is that you can even be sponsored for outdoor activities: This includes all step-based activities such as running, walking and strolling, plus cycling. Of course, no membership with a sports provider is required for outdoor activities.
Your employer decides which sports activities he wants to reward.
