Rizin is your AI personal trainer, nutritionist, and progress tracker in one app. Get a personalized workout plan and nutrition targets in minutes, then let Rizin Autopilot review your week and adjust the plan for you. Available on the web at rizin.app — now on the App Store for iPhone.

Adaptive Workout Plans & Rizin Autopilot #

Personalized splits built around your goals, equipment, schedule, and recovery. Rolling plans keep the weeks ahead topped up automatically, a weekly review shows what improved and what needs attention, and Rizin Autopilot prepares plan adjustments from logged sessions, RPE, and soreness — not a fixed 12-week template.

Log Meals However You Eat #

Search foods and restaurants, scan a barcode, snap a photo with Meal Scan, use Quick Add, or just tell the AI coach what you ate. Rizin logs calories and macros to your daily plan, and BMR/TDEE targets adapt as your body and training change.

24/7 AI Coach #

Chat with your coach any time to ask form or programming questions, log meals or workouts in plain English, swap exercises, or update equipment. One-tap actions take you straight to your workout or meals, and every change flows back into the next plan generation.

Injury & Recovery Aware #

Tell Rizin about an injury and the planner removes conflicting exercises and substitutes safe alternatives. Sleep, soreness, and training load feed a daily readiness signal that tunes today’s session intensity.

Pricing #

7-day free trial, no credit card required. Essential $14.99/month. Pro $19.99/month with Pro Mode, body composition tracking, supplement logging, and optional blood work personalization. Cancel anytime.
