Engineer Performance. Deep Hack the Human Body.
You are unique. Train unique.
Thalos connects training, nutrition, recovery and biometrics into one adaptive coaching system — so every plan responds to the body in front of it. No generic plans. No isolated numbers. One coach. Every signal.
Stop guessing. Start adapting.

One system. Every signal.
Workouts
Structured training. Logged, reviewed and connected to your performance history.
Meals
Nutrition as protocol. Photos, macros, timing and corrections — linked to training and recovery.
Recovery
Sleep and fatigue are not excuses. They are training signals.
Data
Heart rate, HRV, sleep, active energy, steps, lactate and CGM where available — unified in one performance view.
Coach
The AI reads the pattern and adapts the next move.
Your body speaks in signals. Thalos translates.

Your day at a glance
See the key signals that shape today's training: sleep, recovery, heart rate, HRV, activity and readiness.

Recovery that counts
Sleep duration is not enough. Thalos looks at recovery quality, training load and trend — because adaptation happens between sessions.

Macros in context
Calories, protein, carbs and fat only matter when they are connected to the work you do and the progress you want.

Training with feedback
Sets, reps, load, volume and effort become more than a log. They become the input for the next plan.

Notes as signal
Illness, stress, travel, supplements, routines and missed data are not noise. They explain performance.

Built from high-density human performance data.
Thalos is developed around a 26-week real-world performance study with strength athletes in Vienna. The goal is simple: understand how training, nutrition, recovery and biomarkers interact over time — and translate that complexity into better coaching. The data layer includes workout logs, nutrition tracking, wearable signals, glucose data, lactate measurements, blood panels, microbiome analysis, body composition and performance testing. This is science made usable. Not a dashboard. Not a generic fitness app. A performance system.
Thalos is a performance and fitness coaching platform. It does not provide medical diagnoses or therapy recommendations.
You are unique. Train unique.
Generic plans create generic results. Your body does not adapt like everyone else's. Your sleep is different. Your recovery is different. Your nutrition is different. Your stress is different. Your response to training is different. Thalos builds around that difference. The longer you train with Thalos, the sharper your performance profile becomes — and the more precisely your coach can adapt.
Your data is the edge.
