Limitless 90
90-Day 1:1 Performance Coaching for Senior Technical Leaders
August is fully booked. I take on a maximum of 3 new clients per month — and those spots filled before the month started. Book your intro call now to secure your spot for September.
You are good at your job. Probably very good. But at some point in the last few years, something shifted. The energy that used to carry you through the day now runs out before lunch. The focus that made you sharp now requires caffeine to simulate. The weight has been creeping up so gradually you almost didn't notice — until you did. The body that used to keep up with your ambitions is now visibly falling behind. And the gap between how you feel on the inside and what you see in the mirror keeps quietly widening.
You have tried the usual fixes. Productivity systems. Sleep tracking. Better scheduling. Motivational content. None of it works — because none of it addresses the root cause.
Your body has become the bottleneck to everything you care about.
Ivan Aseev
Founder & CTO, Full Stack Fitness
I spent 20+ years leading engineering teams while quietly falling apart underneath. Ten cups of coffee to feel functional until noon. Crashing after lunch. Dragging myself home with nothing left for my family, my hobbies, anything that mattered outside the office. Overweight, foggy, going through the motions — successful on paper, powerless in reality.
Today I jump out of bed in anticipation. I train before the day starts, attack the most important work before lunch, and still have energy left when I get home — for my family, my hobbies, the things that actually matter. I feel strong, capable, and completely in control. Nothing is impossible. Every problem is solvable. I carry that into every room, every decision, every conversation — and people feel it before I say a word. I fixed the engine. Everything else followed.
The system used in this program wasn't built in a classroom. It was built over years of personal trial and error, tested on my own body, and only then validated with a formal certification as an International Personal Trainer and Nutrition Adviser.
Every protocol in this program is built on peer-reviewed research. If you are the kind of person who thinks like an engineer — in evidence, systems, and logic — this matters. You are not being asked to trust a feeling. You are being given a methodology with citations. I publish weekly long-form articles, each citing 10–25 research papers.
I am not selling a theory. I am selling the system that changed my own life — applied 1:1 to your situation. I am the living proof of what I teach.
What this programme does
Limitless 90 is a 90-day 1:1 coaching programme that rebuilds your physiological foundation — the energy systems, cognitive capacity, and physical presence that everything else in your life runs on.
This is not a fitness programme with a performance angle. This is a performance programme built on a physiological foundation.
We work on everything simultaneously: training, nutrition, recovery, sleep architecture, supplementation, and stress management — all engineered specifically around your schedule, your goals, and your life outside the office.
The result is not just a better body. It is a better engine — one that supports everything you want to do at work, at home, and beyond.
This is for you if...
- You work in or around technology, lead people or projects, and think in systems rather than feelings
- You run on caffeine, cortisol and willpower and know it is not sustainable
- You have tried generic fitness approaches that did not stick or did not translate into real improvements
- You are analytical, systems-oriented, and want a science-backed programme that makes logical sense — not motivation-dependent willpower hacks
- You have a specific life you want to live and a body that is currently preventing you from living it fully
This won't work for you if...
- You are looking for a quick fix, a 30-day challenge, or a shortcut — this programme requires 90 days of real commitment
- Your goals are purely athletic — this is not sports coaching
- You are not willing to track, show up weekly, and do the work — the guarantee exists because the system works, not because effort is optional
- You want a group programme — this is strictly 1:1; no cohorts, no shared calls, no strangers in your business
The 90-day journey
Month 1
Installation
Full physiological and lifestyle assessment. Personal protocol designed around your specific situation, goals, medical context, and schedule. Training system introduced — 3 to 5 sessions per week, 10 to 45 minutes, no gym required. Nutrition baseline established. Sleep and recovery protocols in place. First results appear. Direction confirmed.
Month 2
Momentum
System running. Protocols refined based on real data from your first month. Training intensity increases. Visible body composition changes accelerate. Energy becomes noticeably more stable. Habits stop feeling like effort.
Month 3
New Baseline
Operating at a new physiological level. The habits are self-sustaining. The body is stronger, leaner, more capable. The feeling of being in control — of energy, focus, presence, and performance — becomes the new normal. The programme ends. The results do not.
How the programme runs
Day 0
Onboarding
60-minute kickoff call. Full assessment of your current situation: energy patterns, training history, nutrition habits, sleep quality, medical context, stress load, and goals. Your Personal Protocol is delivered within 48 hours.
Every week
Private coaching call
One 1-hour private coaching call. You share your data — how the week went, what the numbers say, what felt hard. We review, adjust, and set the focus for the next week. Between calls, direct WhatsApp access for questions, adjustments, and accountability. Response within 24 hours Monday to Friday.
Every Sunday
Self-assessment
You complete a short scored self-assessment: energy, sleep quality, workouts completed, and any goal-specific metrics agreed at onboarding. This is the data that drives protocol decisions — not guesswork.
Every 30 days
Protocol review
Full protocol review. We look at all data from the previous month, assess what is working, and update your Personal Protocol accordingly. Day 30, Day 60, and Day 90 versions are each a meaningful upgrade on the last.
Day 90
Graduation
Final assessment against the baseline established on Day 0. Full documentation of your transformation. A post-programme integration plan so the results do not stop when the programme does. A clear picture of what the next chapter looks like, if you choose to continue.

- Direct WhatsApp access — async support Monday to Friday, same-day response for urgent questions

- Nutrition framework — protein-first, sustainable, built around your specific food preferences, travel patterns, and daily routine — not a generic meal plan
- Recovery and sleep engineering — specific protocols for your sleep patterns and stress profile
- Supplement stack — evidence-based, form and dose specific, with a cited rationale for every item
- Goal-specific progress tracking — only the metrics relevant to what you are actually trying to achieve; nothing irrelevant, nothing missing

- 6-Pack ABS for Keyboard Warriors (Premium Package) — premium edition including 5 bonus workbooks, paper tracking sheets, and audio version (€30 value, included)
Ongoing Support
What happens after Day 90
The programme ends. The support does not — unless you want it to.
After graduation, you have the option to continue with a monthly support subscription at €100/month. This includes one 30-minute private call per month, access to the weekly Full Stack Fitness community call, and continued async access to me as your coach. All resources remain available.
This is for clients who want to keep the accountability structure in place while pursuing ongoing personal goals — or simply want to know I am still in their corner.
Founding Client Rate
Investment
€249/month
€747 for the full 90 days
This rate is available to the first small cohort only. It will not be offered again once the programme moves to its standard rate of €649/month (€1,947 for 90 days). In exchange, I ask for honest feedback, measurable data, and a case study if the results warrant it.
I take on a maximum of 3 new clients per month. Not as a sales tactic — as a quality constraint. Every client gets my full attention.
