Apple’s New Workout Buddy: AI-Powered Fitness Coaching for Smarter Sweat Sessions

Apple is pushing the boundaries of personalized fitness with its latest innovation, Workout Buddy, unveiled at WWDC 2025. This AI-driven workout coach is designed to provide real-time, data-backed guidance, transforming how users approach their fitness routines. By leveraging your workout history – including paces, miles, activity ring closures, and training load – Workout Buddy dynamically adapts to your needs, offering tailored coaching every step of the way.

Integrating seamlessly with Apple Intelligence on the iPhone, Workout Buddy employs a sophisticated text-to-speech model to deliver motivational cues in a generative voice that mimics a real fitness trainer. This unique feature utilizes voice data from Fitness+ trainers, the experts behind Apple’s Fitness+ app and studio workouts. Users can personalize their experience by selecting from various voices, ensuring an encouraging and engaging workout companion.

The updated Workout app on Apple Watch and iPhone now starts with an uplifting pep talk as you begin your run. It highlights key milestones such as reaching four miles, achieving your fastest mile, and monitoring your average heart rate. Post-workout, Workout Buddy provides a comprehensive summary of your performance, including average pace, heart rate analysis, and any milestones achieved, such as completing your first 10K run.

Workout Buddy will initially be available in English across a range of popular workout types, with plans for future expansions.

Echoing Apple’s commitment to user privacy, the company emphasizes that Workout Buddy is designed to be “personal and private,” ensuring data security and confidentiality.

In addition to Workout Buddy, Apple is enhancing the Workout app on Apple Watch with a streamlined layout, bringing features like Custom Workout and Race Route within easy reach. The app also introduces new media integration for music. Users can let Apple Music curate the perfect playlist based on their workout or preferences, or they can choose from suggested playlists and podcasts tailored to their listening habits and workout type.
