That's why I was intrigued when I read my colleague Rhiannon Williams' latest piece about AI gym trainers. Lumin Fitness is a gym in Texas staffed pretty much entirely by virtual AI coaches designed to guide gym goers through workouts (there's one human employee on hand--to switch everything off and on, perhaps.) Patrons can complete a solo workout program with the help of a virtual coach in their own designated station, or participate in a high-intensity functional training class with others. Sensors in both the equipment and the floor-to-ceiling LED screens that line the walls of the gym track users' movements, and Lumin uses machine learning models to tailor advice. The gym owners are confident that these new AI trainers will encourage people like me who feel intimidated or unmotivated to work out. Over the next few years, artificial intelligence is going to have a bigger and bigger effect on us and the way we live.
