ZENKAI builds a periodized program from your gear, days and strength — every set builds a character sheet that reflects real work. • 8-12 week programs, periodized to your deadline, deloads included • Superset and circuit styles, picked at onboarding • Five stats, six ranks, E to ONI, from what you logged • Log a set in two taps: rest timer, last numbers, quick swap • End of block: next one rebuilds from what you lifted • Share your session, character sheet or finished block
Strength training plan and workout tracker. Find out what rank you actually are.
Most people never find out how strong they could get. ZENKAI is a gym workout app that writes you a real training program, guides every workout, and turns your lifts into a character sheet. Most workout apps show you stats that never move, because they came from a questionnaire. Here, every number comes from the sets you logged. A REAL TRAINING PROGRAM, NOT A RANDOM WORKOUT • Your whole training block is written before day one: a periodized workout plan of 8 to 12 weeks, every session, every set, every weight • Built around your equipment, your available days, your injuries and what you can already lift • Full gym, home gym, or nothing but your bodyweight. The workout plan adapts to what you have • Straight sets, supersets or circuits. You pick how you train, the workout program follows • Progressive overload, deload weeks and weekly training volume per muscle group handled for you • Change your training days, your gym or an injury, and the rest of the block rebuilds around it • Finish the block and the next training program is built from what you actually lifted. Not a reset. A recalculation YOUR TRAINING GETS A STAT SCREEN • Five stats — STRENGTH, ENDURANCE, VOLUME, RECOVERY, DISCIPLINE — computed from your logged workouts • A LEVEL that only goes up, and a RANK you cannot fake. That is what makes it worth something • 19 titles and 41 achievements, every one earned from real strength training. No login rewards. No invented quests • Every formula is open inside the app, with your own numbers in it. Check the math • A rank card you can send to the group chat A WORKOUT TRACKER BUILT FOR THE GYM FLOOR • Log a set in two taps. Big buttons, no keyboard, no squinting • The rest timer starts itself, buzzes at ten seconds, and notifies you if you leave • Last workout's numbers sitting right under today's, so you always know what to beat • Fully offline workout tracking. A dead signal in the basement changes nothing • Machine taken? Swap the exercise in one tap: same movement, your gear, injuries • Movement demos on the main lifts, plus written form cues on every exercise PROOF THAT YOUR TRAINING IS WORKING • Your strength curve and estimated 1RM on every exercise you log • Personal records detected the second you hit them • A volume heatmap by muscle group: see exactly which muscle you keep skipping • Bodyweight chart with a 7-day average, because the daily number is noise • A Sunday night notification with your week: sets, tonnage, rank • Your full workout history, every set you ever logged, exportable as JSON EAT ENOUGH TO GROW • Calories, protein and water, calculated from your body and your training load • One tap to log them. No barcode scanning, no food database, no guilt WHO THIS IS FOR Never trained before? You get a first strength training program you can follow without knowing anything, in the gym or at home. Been lifting for years? You get real periodization, volume managed per muscle group, and a push pull legs or upper lower split chosen for the days you actually have. Either way you stop keeping a blank workout log and start following a strength training plan built for your gym. HOW IT WORKS 1. We build your workout plan 2. You do the work 3.
