Hypertrophy & strength programs for your gym, rebuilt when the rack is taken.
Read full description
Most training apps know WHAT muscle an exercise works. Bimetis knows WHERE it works the muscle.
Bimetis tags every exercise in an 819-exercise database by stretch-load quality — the degree to which it loads the muscle at its longest point, the range most associated with hypertrophy.
REAL PERIODIZED PROGRAMS
Bimetis builds complete 6-week training blocks (mesocycles; 8 weeks for Hybrid programs), not single-day guesswork. Every session serves the larger plan, with volume and intensity that progress week over week. You see the whole mesocycle arc — which week is a build week, which is a deload, and exactly where you are in the block.
A FIRST SESSION THAT SETS YOUR WEIGHTS
Your first workout is a short calibration session — 2 working sets of each exercise — that sets your starting weights for the block.
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. Squat rack taken? Cable station busy? Your session gets rebuilt around what is actually free, and Bimetis shows you how much of the training stimulus survived.
SWAP WARNINGS
When an exercise swap would lose stretch-load quality, Bimetis tells you before you do it — not after. Every substitution is scored on movement pattern, muscle target and equipment match, so a swap made in a busy gym does not quietly cost you progress.
PROGRESSIVE OVERLOAD, HANDLED
Loads and rep targets advance automatically across the block. Finish a session and the next one already has its targets set — no spreadsheet, no guessing what to add.
WHEN YOU STALL, IT NOTICES
If your strength on a muscle stops climbing, your next block upgrades that muscle's exercises to ones with better stretch loading.
FRESH EVERY BLOCK
Each new block rotates in different exercise variations for the same goal, so your training stays fresh.
EXERCISE VIDEO AND FORM CUES
Real demonstration video, sets, reps, rest timing, the muscles each lift actually loads, and plain-language form cues on the exercises where technique matters most.
TRAINING SPLITS THAT FIT YOUR WEEK
Upper/Lower, Push-Pull-Legs, full body and more — matched to how many days you can actually train, not an idealised schedule you will abandon in week two.
SEE THE SCIENCE
Every exercise and every swap shows a match score and a plain-language biomechanical rationale. No black box, no "trust us" — you can always see why a lift is in your program.
WHO IT IS FOR
Lifters who want a real training block rather than a workout generator: intermediate and advanced trainees chasing hypertrophy, anyone returning after a layoff who wants structure, and anyone tired of programs that fall apart the moment a piece of equipment is unavailable.
