About this app

Most training apps know WHAT muscle an exercise works. Bimetis knows WHERE it works the muscle.

Bimetis tags every exercise in an 834-exercise database by stretch-load quality — the degree to which it loads the muscle at its longest point, the range most associated with hypertrophy. No other consumer app tracks this.

REAL PERIODIZED PROGRAMS
Bimetis builds complete 4-12 week training blocks (mesocycles), not single-day guesswork. Every session serves the larger plan, with volume and intensity that progress week over week.

EQUIPMENT-AWARE, EVERY SESSION
Tell Bimetis what equipment you have. It builds the best possible program for your actual gym — and when equipment changes or you travel, it restructures your session without losing the periodization structure.

SWAP WARNINGS
When an exercise swap would lose stretch-load quality, Bimetis tells you before you do it — not after.

SEE THE SCIENCE
Every exercise and every swap shows a match score and a plain-language biomechanical rationale. No black box.

Subscription: $12.99/month or $79.99/year, with a 14-day free trial. Bimetis is intended for generally healthy adults 18 and older; it is not a medical device and does not provide medical advice.
