Rizin — AI Personal Trainer App
Rizin is the AI personal trainer app for adaptive workouts, photo nutrition tracking, and injury recovery. Available on iOS and the web at rizin.app. Start with a 7-day free trial — no credit card required.
Adaptive Workout Plans
Rizin builds a personalized weekly workout plan around your goals, schedule, equipment, training history, and recovery, then adapts it every week based on your real progress. If you skip a day, push harder than expected, or feel sore, the plan reshapes itself instead of staying static.
Injury-Aware Training
Tell Rizin about an injury and it routes around it. The injury safety layer treats injuries as hard constraints — the planner removes any exercise that conflicts with your affected joints or movement patterns and substitutes safer alternatives that still progress your goals.
Photo Nutrition Tracking
Log meals by snapping a photo. Rizin uses GPT-4o vision to identify foods, estimate portions, and calculate calories and macros, then scores the meal with the Rizin Fuel Quality Score so you can see whether what you ate actually supports your plan.
24/7 AI Coach
Chat with Rizin anytime to ask training or nutrition questions, change your plan, swap exercises, log how you feel, or update your equipment. Profile changes flow back into the next plan generation, so the coach actually knows your situation.
Optional Blood Work Personalization
Pro members can upload a recent blood panel and Rizin tunes workouts, nutrition targets, and supplement suggestions to your real lab markers. It is fully optional — the app already generates strong personalized plans without it.
Pricing
Start with a 7-day free trial, no credit card required. The Essential plan is $14.99 per month and the Pro plan is $19.99 per month with advanced features including Pro Mode, body composition tracking, supplement logging, and blood work personalization. Cancel anytime.
