WorkoutReplayAnalyzer: Form Check AI
Upload gym videos and get AI feedback on lifting form, rep counting, and injury risk — designed for home gym users and personal trainers who can't afford form coaches.
The Problem
Most lifters train alone without real-time form feedback, leading to inefficient workouts and preventable injuries. Existing solutions either require expensive in-person coaches, live Zoom sessions, or generic video analysis that doesn't understand barbell mechanics. Home gym users especially have zero accountability for bad form.
Target Audience
Home gym enthusiasts (20-45 years old), budget-conscious lifters, personal trainers who want to upsell form analysis to remote clients, CrossFit coaches reviewing athlete videos asynchronously.
Why Now?
Pose estimation models are free and accurate enough now; previously required expensive APIs. Video upload infrastructure is cheap. Fitness creators are hungry for scalable coaching tools post-pandemic.
What's Missing
Existing PT software focuses on scheduling/payment, not form feedback. Computer vision tools exist but require ML expertise to deploy. No one has built the consumer-friendly bridge between raw pose data and actionable coaching cues.
