Rizin Fitness

Rizin Fitness is an AI personal trainer app that combines adaptive workout planning, photo-based nutrition tracking, and injury-aware programming into a single coaching experience. Built for people who want personalized fitness without the $200/month price tag of a human trainer, Rizin generates a complete plan in minutes and adapts it every week based on your real progress.

WHAT MAKES RIZIN DIFFERENT

Adaptive Workout Plans: Rizin builds personalized splits around your goals, equipment, schedule, fitness level, and recovery — not a fixed 12-week template. The plan updates weekly based on logged sessions, RPE (rate of perceived exertion), and soreness signals.

Photo Meal Logging: Snap a photo of any meal and Rizin's GPT-4o vision pipeline identifies the food, estimates portion size, and logs calories and macros to your daily plan. No barcode scanning, no manual entry, no searching food databases.

Injury-Aware Programming: Tell Rizin about a knee issue, shoulder limitation, or back pain, and the planner removes conflicting exercises and substitutes safe alternatives automatically. This is a hard constraint, not a soft preference — Rizin will not program around injuries you've disclosed.

24/7 AI Coach: Chat with your coach any time to ask form questions, swap exercises, update equipment, or log how you feel. Every conversation flows back into the next plan generation.

Recovery & Readiness Tracking: Sleep, soreness, and training load feed a daily readiness signal that tunes today's session intensity. Train hard when your body's ready, deload when it isn't.

WHO RIZIN IS FOR

Busy professionals who want a coach but not a $200/month bill. People recovering from injuries who need adaptive programming. Anyone who's tried generic fitness apps and bounced off because the plan didn't fit their life. Lifters and runners alike — Rizin handles strength, hypertrophy, endurance, and conditioning goals.
