Apple Launches Workout Buddy AI Coach for Smarter Fitness

At WWDC 2025, Apple introduced Workout Buddy, an innovative AI workout coach designed to transform how users engage with their fitness routines. This tool leverages data from your current workout and your fitness history—such as pace, miles logged, activity rings closed, and training load—to provide personalized, real-time coaching.

Workout Buddy stands out by using a text-to-speech generative voice model that mimics Fitness+ trainers, offering encouragement in a motivating and engaging way. Users can select from multiple voices, ensuring a personalized coaching experience that feels authentic and supportive.

The integration with the Apple Watch and iPhone Workout app means users receive a pep talk at the start of their run, real-time updates on milestones like fastest mile or heart rate averages, and a comprehensive summary at the end highlighting pace, heart rate, and achievements such as first 10K runs.

Privacy remains a cornerstone of Workout Buddy, with Apple emphasizing that the AI coaching is both personal and secure. The Workout app also receives a new layout, making features like Custom Workout and Race Route easily accessible.

Additionally, media integration allows Apple Music to curate playlists or podcasts tailored to the workout type or user preferences, enhancing motivation and enjoyment during exercise.

Why Workout Buddy Matters

Workout Buddy exemplifies how AI can elevate personal fitness by delivering tailored coaching that adapts to individual performance and history. This approach not only motivates users but also helps optimize workouts for better results.

By combining AI with voice technology and seamless integration across Apple devices, Workout Buddy creates a holistic fitness experience that feels both high-tech and deeply personal.

For developers and businesses in health tech, this innovation signals a growing demand for AI-driven, personalized fitness solutions that respect user privacy while enhancing engagement.
