Arnold writes your workout program — gym, cycling, skiing, whatever you do — and rewrites it every morning based on how your body actually recovered. HRV up? He pushes. Poor sleep? He pulls back. Not templates. Real coaching.
Works with Oura · Garmin · Apple Watch · Strava · €19/month · Runs on Telegram
One coach managing the full loop — not four apps that don't talk to each other.
A real training program adapts — to your recovery, your schedule, your equipment, your goals. Arnold writes yours fresh every morning based on what your body actually tells it.
Arnold reads your HRV and sleep data every morning and adjusts the plan accordingly. Low HRV? Intensity drops. Red day? Active recovery only — no exceptions.
Gym, cycling, skiing, running — Arnold programs across all your sports. Knows that yesterday's hard ride affects today's squats. Periodizes the whole picture.
Travelling? Arnold reprograms for the hotel gym. On a ski trip? It shifts to skiing focus. Back home? Smooth transition. No static plans.
Heavy endurance week? Carbs go up. Rest day? Calories drop, protein stays. Arnold adjusts your nutrition targets to match your actual programming.
Arnold lives in Telegram. The interface is a chat — but behind it is a coaching system that reads your biometrics, tracks every session, and rewrites your program every morning. No app to install. No dashboard to check.
Tell Arnold your goals, sports, equipment, and any injuries. Connect your Oura, Garmin, or Strava. Arnold builds your initial training program and you're set.
Every morning: recovery snapshot + today's workout with specific exercises, weights, and rep targets — calibrated to how you actually slept and recovered. Your HRV from last night drives what happens today.
Tell Arnold what you did — text, voice note, or just let Strava sync. Arnold tracks your progression, adjusts next week's program, and pushes you forward. Every week builds on the last.
Not just last week. Every workout, every weight, every sleep score, every PR. Arnold sees patterns you don't — and uses them to make you better.
Progressive overload — "Last week you benched 25kg for 4×5. HRV is up 11%. Today we're doing 27.5kg."
Recovery management — "HRV has been dropping three days in a row. This week we're deloading whether you want to or not."
Context shifts — "You're at a hotel gym with dumbbells up to 20kg? Here's your adjusted session."
Injury-aware — "Shoulder still rehabbing. No overhead pressing today — we'll work around it."
"I told Arnold I was skiing in Lapland for three weeks. It reprogrammed everything around XC skiing — and when I got home, it eased me back into the gym. Try getting that from Fitbod."

No. Arnold works with Garmin, Apple Watch, and Strava too. The more data you connect, the smarter the programming — but you can start with just Strava or even no wearable at all.
Yes — specific exercises, sets, reps, and weights based on your equipment, goals, and progression. Not a generic "do 3 sets of 10." Arnold tracks your numbers, pushes them forward every week, and adjusts intensity based on your recovery data.
Strength, cycling, running, skiing, mobility — any combination. Arnold manages training load across all of them and periodizes the whole picture. You ski in winter and cycle in summer? Arnold plans for both.
Because the magic isn't in the UI — it's in what Arnold knows. He reads your HRV, tracks every session, remembers your PRs, and rewrites your program. All of that happens behind the scenes. The chat is just how you communicate with it. No app to install, no dashboard to navigate. Arnold messages you every morning and you message back. Log a workout in 10 seconds with text or voice.
No. ChatGPT doesn't know your bench went up from 20kg to 27.5kg over six weeks. It doesn't know your HRV dropped 15% this morning and you should be training lighter today. Arnold knows both — and programs accordingly. The difference is memory plus biometrics. No chatbot has that.
€19/month or €179/year — about the same as Zwift or Rouvy, but for coaching across all your sports. Beta users get founding member pricing.
