If you share an exercise with everyone in the software, the following happens:
The exercise becomes public: It becomes available to all platform users. Other trainers or users can view and use it in their own training programs.
Available in the database: The shared exercise enters the general exercise database, accessible to everyone. This is useful for sharing an effective or unique exercise with the community.
Sharing an exercise with everyone contributes to the community and increases options for all trainers and users.
