Engaging Gym Class Promotion Designs Needed

We are a private studio and a pro boxing gym that has Moved locations (our own building)
we have upscaled the new location to be more spacious and nicer in general.

for 15 years we have thrived on 1-to-1 training (client books a coach)
We are launching a new format of training for our clients
it is training in a boutique group format (we won't ever exceed 10 people per class)
The classes each have 1 senior instructor and the junior that assists to ensure everyone gets good quality training (ie Female focused classes,
Box Class, BoxFit , HIIT Boxfit and Kids Classes)
Each class has been structured by the head instructor to be a highly engaging, energetic and fun.

Classes happen against a schedule that is available on our booking platform
People can log in to the app and see what class is happening at what time & on what day and make appointments accordingly.

We are a contract and membership free business (people pay month to month) nothing binding.

Clients pay buy a 30 day Class pass and can attend as much or as little as they want - to launch were having 30% off

We have taken photos of our 3 senior coaches and we need highly engaging designs for social media and website that sells them and their class (eg. box fit etc)

We need to create a compelling advert/designs for social media and for our website that highlights the whole offering and adverts/designs that can accompany the offer that shows schedule and markets each class with its respective head coach
