Pay-once Claude skill that writes a workout app around your injuries and goals.
IRON/OS is a pay-once Claude skill (£25 one-time) that interviews you on your goals, equipment, weekly schedule, injuries and current lifts. It then writes a training programme that works around those injuries and constraints, plus a single-file workout app you save to your phone and use at the gym. An optional meal plan can be added to match the programme. Your data stays on your device. No extra subscription (needs a paid Claude plan). Fitness guidance, not medical advice.
