If you’ve ever wanted a trainer in your ear—one that actually knows your stats in real time—then you’ll like what Apple just announced at WWDC 2025. Called Workout Buddy, the watchOS 26 feature uses Apple Intelligence to generate real-time, motivational feedback during workouts based on your heart rate, pace, distance, and fitness history. For example, depending on your specific data, you might hear, “Your last mile was your fastest yet!”

The voice doesn’t sound robotic, either. Apple uses Fitness+ trainer voices to give Workout Buddy a tone that’s energizing and human. It can track milestones, call out progress, and even give you a recap when you finish. The feature works with Apple Watch and Bluetooth headphones, provided your phone is nearby. At launch, it will support English only and work across many popular workout types like running, walking, cycling, and strength training.
