Core pillars

What Rockso brings you

Rockso connects your reality, your full practice and principles drawn from both science and the field to help you make the right choices and stay in the right rhythm.

Understand your real load

Rockso does not only look at volume or intensity. It puts the sequence of your sessions, your history, recovery and everyday stress into context to understand when load drives progress, and when it becomes too heavy to absorb.

Connect your full practice

Running, cycling, triathlon, football, padel, tennis, skiing... Rockso does not split your practice into silos. It connects what your body is already adding up to give you a unified reading of your load.

Respect your rhythm

Rockso draws on sports science and field feedback to help you make decisions that respect your state of the day. The goal is not to always do more, but to stay in the right rhythm, preserve momentum and build progress that lasts.

The right training is not the hardest. It is the one your body can turn into progress.

For people who want to last and progress

Athletes, coaches, organisations: Rockso brings a clearer reading of load to help people decide better, adjust better and support better.

Athletes & committed amateurs

A good preparation is one that fits your life. Understand what your load is truly producing, identify what you can absorb, what wears you down, and when to adjust to stay consistent over time.

Build sustainable preparation

Coaches & performance staff

Gain a clearer view of your athletes' real load, context and recovery. Visualise useful signals, follow conversations and make decisions faster without losing your philosophy or standards.

Strengthen your decisions

Clubs, academies & staffs

Share a common reading of load, clarify decisions between the field, physical preparation and medical teams, and align choices around availability, progress and continuity.

Structure collective load
Science

A method grounded in reality

Decisions informed by science and the field

Rockso combines scientific literature, field feedback and individual signals to guide the right decisions at the right time. The goal is not to accumulate metrics, but to make load, fatigue and recovery easier to read so you can adjust better over time.

  • Grounded models, then adjusted to field reality.
  • An individual reading: no copied formulas, no imposed averages.
  • Understandable signals for defensible decisions.
Physiologist Jack Daniels

Training itself is not what drives progress. The adaptations it enables are.

Co-build with the field

Rockso is built with teams, coaches and organisations who want to confront models with real practice, refine decisions and build a fairer standard for load monitoring.
