About FitSI

Why FitSI exists

Most people who want to train regularly do not lack workouts. They lack a plan that fits this week: the run that did not happen on Tuesday, the short night, the hotel room with no equipment.

FitSI is an attempt to give that job to a coach that remembers your goal, your limits and your equipment, and that you can reach in the messenger you already use.

How it is being built

FitSI starts with a four-week personal pilot: the founder’s own running plan with HIIT sessions. Family and friends join after that pilot is evaluated. A wider pilot follows only after data export, deletion and backup restore are tested.

Usefulness is measured plainly: completed sessions, reasons for missed ones, manual corrections to recommendations and time spent planning.

Principles

Restrictions are facts, not preferences. Missing data is not good news. A photo is a suggestion until you confirm it. AI proposals are checked by the application before you see them.

This site describes plans as plans. There are no invented reviews, user counts or results here.
