01Your goal
Describe it in your own words.
Plain text. No dropdowns. A boxer types "fight at 70 kg without gassing in round three." A mom types "get my squat back to 80 kg and play with my kids." Athilion accepts both.

Every fitness app treats you like a stranger. Athilion treats you like an athlete it actually knows - your injury, your weight cut, your comeback - and rewrites your training and nutrition every week until the goal is yours.
Free 15-min onboarding. Try it out for free and create your own program.
The status quo is broken
Three apps. One spreadsheet. A YouTube search. And still no one who sees your day-to-day.
A motivated athlete stitches together three apps, a spreadsheet, and a YouTube search - and still gets a plan that ignores their sport, their injuries, their schedule, and their body. Software in 2026 still forces this.
Training
Your training app doesn't know what you ate.
Nutrition
Your nutrition app doesn't know you're cutting weight for a fight.
Coaching
Your coach costs hundreds a month and still can't watch your set at 6am.
Your goal
Your goal is specific. Your plan isn't.
The only thing that actually works is hiring a personal coach and a nutritionist - hundreds of euros a month, and they still can't see your day-to-day.
Athilion rebuilds that coaching relationship as software - one that remembers, adapts, and sees everything.
Four steps. From your words to your next journey.
You describe it. Athilion makes it measurable. A multi-phase roadmap appears. Every week after that, it rewrites itself.
- 02North Star
A wish becomes measurable.
Lio reads your goal and proposes concrete metrics that define success for you. Strength numbers, skill targets, body comp, sport-specific conditioning. You review them in conversation.
- 03Roadmap
A phased journey, not a 12-week template.
Your North Star becomes a multi-phase plan shaped by your timeline - each phase designed around a specific stimulus, chained into a clean line from where you are to where you're going.
- 04Adaptive plan
Re-written every single week.
Mid-session adjustments when you're sore. Macros redistribute when you play football Saturday. Volume backs off when you're sick. Monday morning, Lio rewrites next week against the same North Star.
One coach. Training, nutrition, and everything in between.
Sessions engineered in blocks. Meals logged in three seconds. A coach that remembers forever and rewrites the whole plan when life moves. All in the same app. All adapting to the same North Star.
Every session
A session built block by block. Not a flat list.
Every block has a job - activation, main strength, density, engine, skill work, accessories. The set of blocks adapts to the phase and the goal you're chasing.

Meet Lio. The coach built around you.
Lio is the AI coach living inside Athilion. Not a chatbot bolted onto a tracker - the reasoning layer underneath every session, every meal, every week. It watches, remembers, and rewrites the plan in concrete numbers, not generic advice.

Right knee felt off on set 2 of back squat.
Capping depth, dropping from 5x5 to 4x4 at the same load, and swapping lunges for split squats. Same training effect, less shear on the knee.

A slice of what Lio remembers about you - pulled into every session, every meal plan, every adaptation.
Everyone else built a CRUD app with a chatbot. We built the first real AI fitness system.
Training, nutrition, and coaching live in one system - grounded in a single North Star, with persistent memory of you. Nobody else ties all three together.

One coach. Many ways to chase a goal.
The athletes who outgrew generic apps. The ones with specific outcomes and real constraints. Lio adapts to each of them.
Built by
Two athletes who couldn't find a solution.
One of us trains Muay Thai and needed training that respected sport practice. The other does calisthenics and was watching generic apps fail people with real skill goals.
So we built Athilion - the coach we couldn't find.

No ads. No enterprise tiers. The athlete is the customer.
The short answers. The honest ones.
These are the questions we hear most - about beginners, coaches, injuries, schedules, and what happens once you commit. If yours isn't here, starting is free - and we're happy to answer anything personal on our socials or by email.
- 01Is Athilion good for beginners?
Yes. Whether your goal is "do my first pull-up," "lose 10 kg and feel strong," or simply "stay healthy and consistent" - Athilion builds a plan around it. The more specific your goal, the sharper Lio can get.
- 02Who is Athilion for?
Everybody. But especially athletes with specific outcomes - a fight, a skill, a comeback - or anyone who needs training and nutrition shaped around their main sport. If a generic plan has ever let you down, you're who we built it for.
- 03Does it replace a personal coach?
A personal coach can read your body language and push you in the moment. We can't do that. What we can do is be there whenever you show up and adjust your training and nutrition right when it counts, not days later at your next appointment.
- 04What if I have an injury?
Tell Lio in onboarding (or any time after). It's remembered forever. Lio caps loads, swaps exercises, and keeps the training effect intact.
- 05When can I see what I'm getting?
Onboarding is free and takes around 15 minutes. By the end you've seen your North Star, your phased journey, and your first week - plus 7 full days on the plan to actually use it. Then - and only then - we ask you to subscribe.
Tell Athilion your goal.
Fifteen minutes to your first plan - your North Star, your phases, your first week. Seven days on the full plan to actually use it. Then - and only then - we ask you to commit.
