Fortis Calisthenics

Fortis adapts your training plan every single day based on how you actually performed — not a fixed schedule someone else decided for you.

Fortis Calisthenics is a training app built around one idea: your programme should respond to you, not the other way around. Tell Fortis what you can do today and where you want to get to. The algorithm works out how long it will take and builds a daily session around your current ability — sets, reps, and rest periods calculated from your actual maximum, not a generic plan. Every day you log how it felt. Too easy? Fortis pushes harder. Struggled? It eases off. The plan rebuilds itself around your real performance after every single session.
