iPhone
Lifts drawn as looping stick figures, mistakes marked in red, and a rest timer that starts the moment you tick off a set. Your training, penned.
Sterkt is a training notebook — the paper kind, ruled and ink-stained, that happens to live on your phone. Plan your week, tick off sets on the gym floor, and learn the lifts from small hand-penned stick figures that loop the movement with correct form.
EVERY LIFT, DRAWN RIGHT
62 exercises — barbell, dumbbell, kettlebell, machines, cables and bodyweight — each written out in full: setup steps, execution, breathing, form cues, common mistakes, and the things you should never do, marked in red. Browse by body part or equipment, or just search.
The written pages are free for all 62 exercises. The free notebook animates a 22-exercise starter set; Sterkt Pro brings the looping drawing to every exercise in the library.
BUILD YOUR WEEK
Write a routine, split it across training days and pin each day to a weekday, with the sets, reps and rest for every lift. Start from the free Full Body ×3 programme or a blank page. Sterkt Pro adds the Upper/Lower ×4 and Push/Pull/Legs ×6 templates and room for as many routines as you like. Turn on reminders and Sterkt nudges you on training days, at the time you choose.
ON THE GYM FLOOR
Open today's page and train. Log reps and weight in kilos or pounds; a lift you've logged before opens on the numbers you wrote down last time. Tick off a set and the rest timer starts by itself, floating above the notebook, with +30 seconds when you need it. Finish, and the session is signed into your workout log with its time, sets, exercises and total weight lifted.
COACH'S NOTES
Ten short, evidence-based notes on eating, protein, hydration, sleep, rest days, warming up, soreness, progressive overload, deloads and how to split your week. No bro-science, no supplement pitch. Free for everyone.
PRIVATE BY DESIGN
Your routines and your log stay on your phone. No account, no feed, no streaks, no ads, no tracking. Training guidance is general information, not medical advice.
ENGLISH, FRENCH AND GERMAN
Pages, buttons, dates and reminders follow your iPhone's language in English, French or German. The exercises and coach's notes are written in English for now.
STERKT PRO
The free notebook holds one routine (start it from Full Body ×3 or a blank page), the written guide to all 62 exercises, the animated 22-exercise starter set and every coach's note. Sterkt Pro adds the animated drawing for every exercise, unlimited routines and every template:
