Every workout, written for the body you have today.
Your body has its own math. Styrki learns your recovery speed, strength curves and volume tolerance — then writes every session to match. Lifts and runs, one app.
Free to log workouts forever. Styrki AI free for 7 days.


A coach with a memory
Styrki generates your workout in seconds using championship-proven periodization — volume, medium and intensity days rotated around what your body has actually recovered from. And your coach remembers every chat and voice session, so advice builds instead of resetting.
- Every weight, set and rep recalculated each session as you get stronger
- Fatigue-aware: it backs off the muscles you hammered on Tuesday
- Ask “what did we say about my knee?” — get the answer, with the date
A coach with a face and a voice
Pick a coach or build your own. Yours can talk you through a workout live — hands-free, eyes on the bar — and everything you tell it lands in the same memory as your training data.
Example conversation — this is what coach memory does

One number for the body you've built
Activity, aerobic fitness, strength, recovery and wellness — measured separately, rolled into one 0–100 score you can watch climb. It's the honest answer to “is all this training working?”
- Five components, one score — updated as you train and recover
- See exactly which component moved after every session
- Climbs from Foundational to Elite — and tells you what's holding you back

Log a set in two taps
Weights come pre-filled from your history, so logging is tap plates, tap done. The instant a set beats a record, Styrki catches it — all-time, this year, or current — without you checking a spreadsheet.
- Two taps per set — no typing mid-workout
- Automatic PR detection: all-time, year and current, at every rep count
- Your 1RM, 5RM and 10RM all tracked — records never overwrite each other

Runs, read like a coach reads them
GPS tracking with live pace and heart rate is the baseline. Styrki goes further: guided Norwegian 4×4 intervals with voice countdowns, and post-run analysis — grade-adjusted pace, aerobic decoupling, efficiency — that tells you what the run actually did.
- 4×4 HIIT intervals with your coach counting you into every rep
- Grade-adjusted pace, decoupling and efficiency on every run
- Physiology records — steadiest run, best negative split, most Zone 2 — not just fastest 5K

Why not just keep your logger?
A logger records what you did. Styrki decides what you do next.
Other loggers store your numbers.
Styrki learns from them — your recovery speed, your strength curves, your limits.
A template gives everyone the same week three.
Styrki knows what Tuesday cost you and writes Thursday accordingly.
A spreadsheet doesn't notice your PR.
Styrki catches it the second you log the set — and celebrates like it means it.
