Give people a useful reason to look closer
A good class post helps someone understand something about your studio. It might show your teaching, explain a class or let the atmosphere come through.
Choose one thing to communicate
Before choosing footage, decide what you want someone to take away. For example: how a beginner lesson works, what a particular fitness session involves or where to find the next course dates.
Use footage that supports the message
If the message is about learning, show teaching or practice. If it's about the group experience, show participation. Keep the footage and words connected.
Be specific about your studio
Details such as the class type, location and teaching approach help a viewer decide whether to find out more. Use claims you can support and check that timetables and offers are current.
Give the viewer somewhere to go
Finish with a clear action: view the timetable, read about the class or book through your usual system.
Look beyond the view count
Notice the questions, inquiries and bookings that follow your activity. Ask new students how they heard about you. Treat that information as useful evidence without assuming every outcome came from a single post.
