AI Fitness Coach & AI Health Coach — Rizin

Rizin is your AI fitness coach and AI health coach in one app — generating adaptive workout plans, personalizing nutrition and meal planning, adapting around injuries, and (optionally) tuning your entire program from blood-work markers. Available 24/7. Learn how Rizin works or explore the full feature set.

Adaptive Plans That Update Every Week

The AI coach doesn’t hand you a static 12-week program. It reads your logged sessions, RPE, soreness, and schedule, then rebuilds the week ahead based on what you actually did. Volume goes up when you’re progressing; intensity pulls back when you’re fatigued. Every change is explained so you understand the reasoning.

Injury Adaptation — Real-Time Plan Changes

Tell the coach about a knee problem, shoulder strain, or any pain and your plan regenerates immediately — removing conflicting exercises, substituting safe alternatives, and adjusting overall intensity. As you log improvement the coach progressively reintroduces load. You keep training; the coach routes around what hurts.

Blood-Work Personalization (Pro)

Upload your blood-work panel and the AI coach translates markers like ferritin, vitamin D, fasting glucose, and TSH into concrete plan changes: intensity caps for low iron, carb adjustments for elevated glucose, supplement priorities for deficient B12. Every adjustment is shown on your dashboard with the marker that triggered it.

Meal Planning & Nutrition Coaching

Log meals by photo, barcode, or plain text. The coach calculates your TDEE and macro targets, generates a 14-day meal plan, and adjusts both as your body and training load change. Ask it what to eat before a workout, whether a meal fits your plan, or to swap a recipe — in plain language, any time.

Full Context, Every Conversation

The coach carries your goals, training history, injuries, equipment, recent sessions, and nutrition data into every chat. Profile changes — new equipment, updated schedule, a new injury — flow back into the next plan generation so they actually stick.
