I built an autonomous AI coach for strength, injury rehab & meals after a shoulder injury (20 free beta spots)

Five years ago I dislocated my shoulder. It turned into a permanent injury, and a doctor gave me two options: surgery, or daily training and rehab.

I chose training — high-intensity workouts, sports, lifting, and rehab every week. Showing up wasn't the hard part; knowing what to do was. My routine was scattered across a workout logger, gym classes, Garmin for sleep/recovery stats, and Claude where I pasted gym-board photos every Sunday. Nothing tied my lifting, my shoulder rehab, and my nutrition together.

So over the last 6 months, I built PanTrainer — an autonomous AI coach that runs my entire training, rehab, and nutrition loop in one place.

How the autonomous AI loop works:

• Autonomous Weekly Programming + Rehab (PubMed-grounded): Plans your training week around your goals, equipment, and nagging injuries, citing actual exercise-science research papers. My shoulder rehab is built automatically into my warm-ups and working sets, and weights progress week-to-week based on my logged sets and RPE.
• Biometric & Real-Life Adaptation: Syncs sleep, HRV, and resting heart rate from Garmin, Apple Health, or Health Connect. Slept badly, feeling sore, or only have 30 minutes today? The AI autonomously adapts today's session or rebalances the rest of the week (and shows you a diff to approve or edit).
• Autonomous Fridge-to-Macro Chef & Photo Logging: Snap a photo of your plate to log calories and protein in seconds. Every week, it checks what's expiring in your fridge, plans high-protein dinners scaled to your training days, and updates a shared household grocery list.

Six months in, I'm lifting heavier than I did before the injury while keeping my shoulder rehab integrated into every week.
