WorkoutGPT - AI Health Harness

Ask questions about your activity, workouts, sleep, training load, fitness age, or progress and get clear answers directly in the chat. WorkoutGPT can use structured health and workout tools to analyze your real data and return more precise, personal, and useful results.


New: Quick Fitness Report

Get a compact overview of your current fitness status in seconds. The Quick Fitness Report summarizes key health and training signals such as VO2 max, resting heart rate, TRIMP-based training load, last night’s sleep, and your current fitness age. It is designed for quick daily check-ins, recovery awareness, and understanding how training and sleep affect your fitness state.
