A CrossFit / functional-fitness box — programs and classes, an on-ramp, coaches as bookable resources, a community gallery, memberships, reviews and a free-intro booking, over the app's own /api.
Open Forge — CrossFit Box in the no-code builder and it reshapes itself as you chat — rename it, retheme it, add screens, change the data model. Publish when you are ready. You are not editing a page: the template is a complete product, with a web app, a native mobile app, a REST API and a seeded database.
