About Arvo
AI that actually coaches. Built by athletes, for athletes.
Arvo is an AI personal trainer app for bodybuilding and powerbuilding, developed by Aetha AI in Italy. It uses 20 specialized AI agents to provide real-time, set-by-set coaching during your workout. The app implements proven training methodologies (Kuba Method, Mentzer HIT, FST-7, Y3T, Mountain Dog) with scientific fidelity. Available as a free app with Pro features at €4/month.
Our Mission
“Every set deserves decisions based on real data, not guesswork.”
Arvo was born to democratize access to intelligent coaching. We believe that advanced training science and AI-powered guidance shouldn't be reserved for elite athletes with expensive coaches. Everyone who steps into a gym deserves a coach that adapts in real-time.
Our Story
The Frustration
Arvo started from a simple frustration: fitness apps that track workouts but don't actually coach. Spreadsheets that log numbers but can't tell you what weight to use next. We saw a gap between what technology could do and what was available to gym-goers.
The Problem
Existing apps were either too simple (just tracking) or too rigid (fixed programs). None could answer the fundamental question every lifter asks: 'What should I do next set?' We knew AI could bridge this gap.
The Solution
We built a system of 20+ specialized AI agents, each handling a specific aspect of training. Not a single monolithic AI, but a team of experts: one for exercise selection, one for progression, one for fatigue management, one for learning your patterns.
Today
Arvo is now a complete AI coaching platform implementing real training methodologies with scientific fidelity. Kuba Method, Mentzer HIT, FST-7, Y3T, Mountain Dog — not simplified versions, but complete implementations with hundreds of lines of methodology rules. See our pricing →
