Arvo

Arvo is an AI-powered coaching app that goes beyond workout logging to provide adaptive training guidance. Instead of static progression, it uses specialized AI agents to autoregulate based on your reported RPE, soreness, and biomechanics across methodologies like Mentzer HIT, Kuba Method, and FST-7. The app features natural language logging where you describe how you felt, and the system automatically adjusts exercises and rest periods accordingly.

Designed for serious lifters who follow fatigue-based periodization systems, Arvo enforces methodology-specific rules while managing progressive overload intelligently. The maker states it uses GPT-5 reasoning models to handle the multi-variable logic of training without hallucinating unrealistic progressions. Currently in open beta with a free plan available.
