Open source means that the source code of software is public, and anyone can view, use, modify and distribute it. Open source gyms can be realized in the following ways:

1. Gym management system: Gyms can use open source gym management systems, such as PowerSport Gym Booking applet and Gym Management System based on SpringBoot.

2. Open source hardware devices: gyms can use open source hardware devices, such as OculusQuest2VR headphones.
