Based on the limited information available, it's impossible to create a comprehensive summary of "Professional Fitness Szczecin" services and activities. The task required an analysis of their Facebook page, which I am unable to perform without access to the content. However, based on the context, it's safe to assume the company offers fitness services, targeting individuals in Szczecin. Their unique selling points and business activities would be related to providing fitness services, marketing on Facebook, and interacting with customers. A detailed summary in Polish is not possible without the Facebook page content.
