Apple’s new Workout Buddy helps you sweat smarter

June 10, 2025

Apple has launched at its WWDC 2025 conference Workout Buddy, an AI workout coach. The AI tool gathers data from both your current workout and your fitness history — including paces, miles logged, activity rings closed, and training load — to coach you through workouts in real time.

Combined with Apple Intelligence on the iPhone, Workout Buddy relies on a text-to-speech model to translate encouragement into a fun generative voice that sounds like a fitness trainer. In fact, the generative voice is built using voice data from Fitness+ trainers — the people who lead workouts within Apple’s Fitness+ app and studio. Users can choose from multiple voices to find the right one for them.

The Workout app on the Apple Watch and iPhone will also update so it kicks off with a pep talk once you start on a run. It will also mark moments, like when you hit four miles, if your last mile was the fastest yet, and what your average heart rate is. At the end of the workout, the AI gives you a rundown of your average pace, heart rate, and whether you hit any additional milestones, like your first 10K run award. Tech Crunch
