Strength programming, engineered.
Open KraftSport Coach Public Beta The problem Strength progress stalls when programming is guesswork. Spreadsheets do not understand fatigue, RPE, or periodisation.
What we built KraftSport Coach plans and adapts strength training — progression schemes, load management, and analysis built on how strength is actually trained. IRI, the AI coach inside, reads your logged sessions and adjusts the plan.
Features IRI responds to logged performance — not a static spreadsheet. RPE and volume tracking that flags overreach before it costs a week. Estimated 1RMs, trends, and PRs — clearly visualised.
