'This just knows so much more than a human ever could': Meet CoachCube, the intelligent AI personal trainer that lives inside a Tron-style box room

Man taking part in the CoachCube workout class.

Fitness in 2026 feels like it's pulling in two very different directions at once. On one hand, artificial intelligence is continuing to colonise the gym floor — largely from AI-powered coaching apps, but also via new analysis of data points from wearables, gently nudging you off the sofa based on sleep and recovery data collected from the likes of the best smartwatches, best smart rings or your form factor of choice. Whether you like it or not, your next workout will probably have an algorithm involved somewhere, requiring zero element of human interaction.

Yet, should you scroll through any city-based social feed right now, you'll find a counter-movement in full swing. All year round, run clubs are booming. People are lacing up not just for the miles, but for the social scene, the post-run coffee catch-up and the sense of occasion of ticking something off early doors. Fitness, for a growing number of people, is the new social life.
