Volition
Your training. Your rules.
Your AI.
Volition is the workout tracker where the AI you already use becomes your personal trainer — building your plan around your philosophy, reviewing your sessions, checking your form — while you keep the final say on every rep.

How it works
Three steps from empty page to a plan that's actually yours.
Connect your AI
One-time setup links Claude or ChatGPT to your tracker. Your AI can read your training picture and write plans, prescriptions and notes — through typed, validated tools.
Get interviewed, not templated
Your coach interviews you — goals, history, schedule, equipment, injuries — or takes the program you already love and transcribes it faithfully. No philosophy yet? It guides you from your goals and builds one with you, explained step by step.
Train, decide, progress
The app runs your sessions: timers, tempo clicks, effort logging. After each exercise, next time's numbers are set by you — or reviewed by your AI when you finish. Never by a hidden rule.
Why Volition
Every other app makes you choose: dumb logger or somebody else's algorithm. Volition is the third option.
Bring your own AI
Your coach is a frontier model with your complete history in context — not a rules engine. It runs on the subscription you already pay for.
You stay in charge
The app remembers and enforces what you decided. Progressions are yours to set — with advice on tap, never on autopilot.
Any training philosophy — or none yet
Strength, hypertrophy, calisthenics, kettlebells, rehab. Bring your own methodology, or let your coach shape one around your goals. Either way it's a living document that changes only when you say so.
Form checks from video
Record a set; your AI reviews motion-sampled frames like a coach watching ringside, and gives you the one cue that matters.
Charts that build themselves
Your AI designs progress charts around your goals; they render from your live logs and stay current forever.
Take your data with you
Every log exports in one tap as a single file. The app works offline. Your coach sees exactly what you see — nothing hidden either way.
Questions, answered
Which AI assistants work with Volition?
Claude and ChatGPT connect directly (Volition speaks MCP — the open Model Context Protocol). Perplexity and Grok are supported with prefilled handoffs, and any MCP-capable assistant can plug in — it can even register its own launch link.
Do I need a separate AI subscription?
No. Volition uses the assistant you already have. Your chats stay in your assistant; your training data stays in Volition; the two meet through a connector you authorize once.
How is this different from Hevy, Strong or Fitbod?
Hevy and Strong are excellent loggers — but they don't coach. Fitbod and similar apps coach — but with their philosophy, not yours. Volition gives your own AI the full picture and keeps you in command of every decision.
Can it really check my form?
Yes, with honest limits — quality depends on the AI you connect. Record a set and Volition sends your AI key frames, sampled densely where the movement actually happens. The best frontier models genuinely read body position: setup mistakes, depth and range of motion, bar drift, asymmetries — and give you a concrete cue. What stills can't capture: bar speed, precise joint angles, or the judgment of an in-person coach on a max attempt. Treat it as a sharp extra pair of eyes, not a spotter.
What if I already have a program I love?
Perfect. Tell your coach "I know exactly how I want to train" and it transcribes your program faithfully — sets, weights, schedule, videos — and only fills the gaps. Its job is safety and bookkeeping, not redesign.
Is it free?
Yes for early adopters — we need your feedback! You bring the AI subscription you already have; Volition adds no fees on top.
Train on your terms.
Set up takes about two minutes. Your first plan takes one conversation.
