The challenge

A workout programme can deliver information. A digital ecosystem can build a relationship.


BUFF’s founders were selling workout programmes through books and PDFs.

The content existed, but users had no connected environment in which to follow their programmes, record workouts, understand progress or remain engaged over time.

The opportunity was to transform static fitness content into an ongoing digital experience.

The solution

From workout plans to a recurring fitness experience.


We transformed BUFF into a subscription-based fitness ecosystem where users can follow structured programmes, complete workouts, track performance and understand their progress over time.

Gamification, achievements, community, analytics and engagement mechanics were layered around the core training experience to create more reasons for users to return.

The product became more than a digital version of a programme. It became the environment in which the user’s fitness journey takes place.

The ecosystem

Training, progress and motivation in one experience.
