Virtual Reality Fitness Coach Headset UI Workout Overlay

Treat virtual reality fitness coach headset ui workout overlay as a polished product design prompt for VR fitness users working through guided VR exercise. Show floating metrics around the user with rep count, heart zone, trainer cue, form warning, and session progress. Include floating metrics, rep count, heart zone, trainer cue, and form warning while keeping the product useful for VR fitness users. Make the hierarchy easy to scan, with meaningful labels, realistic microcopy, responsive spacing, hover or tap states, and accessible contrast. Add empty, loading, and error states where they would naturally appear, so the interface feels like a complete UI/UX case rather than a single decorative screen.
