Problem

70% of people in their 50s have chronic pain in at least one of their knees, back, or shoulders, but after being told 'just exercise' by their doctor, they don't know specifically which exercises to do or how. YouTube workout videos target people in their 20s-30s, and overly strenuous movements can worsen conditions. One-on-one physical therapy sessions cost $22-37 per visit, making 2-3 sessions per week financially burdensome. Ultimately, people give up exercising, neglect their pain, and frequently end up needing surgery.

Solution

Input your pain location, intensity, and diagnosis, and receive a week-by-week self-exercise program based on orthopedic and rehabilitation medicine guidelines. Each movement is explained with text and illustrations, including safety guides like 'stop if you feel this type of pain during this movement.' Bi-weekly to tri-weekly reminders plus pain change tracking monitor progress.

Target: Ages 50-62, with chronic knee, back, or shoulder pain, who have been advised by doctors to exercise but don't know specific methods
Revenue Model: Basic exercise program (4 weeks) free. Advanced pain-specific programs + exercise progress Report at $3.70/month, plus referral commission from rehabilitation clinics and physical therapy centers
Ecosystem Role: Education
MVP Estimate: 2_weeks
