ZENKAI: Gym Workout RPG

Most people never find out how strong they could get.

ZENKAI writes the program that gets you there, then turns every set you log into a level, a rank and five real stats. Not stats from a quiz. Stats from the bar.

Answer the questions. Get a real plan. Do the work. The number goes up because you made it go up.

YOU NEVER WALK IN WONDERING WHAT TO DO
• Your whole block is written before day one: 8 to 12 weeks, every session, every set, every weight
• Built around your equipment, your days, your injuries and what you can already lift
• Full gym, home gym, or nothing but your bodyweight. It works with what you have
• Straight sets, supersets or circuits. You pick how you train, the plan follows
• Progressive overload and deload weeks handled for you. You just show up
• Change your days, change gym, hurt a shoulder, and the rest of the block rebuilds around it
• Finish the block and the next one is built from what you actually lifted. Not a reset. A recalculation

YOUR BODY GETS A STAT SCREEN
• Five stats — STRENGTH, ENDURANCE, VOLUME, RECOVERY, DISCIPLINE — computed from the sets you logged
• A LEVEL that only goes up, and a RANK you cannot fake. That is exactly what makes it worth something
• 17 titles and 41 achievements, every one of them earned. No login rewards. No invented quests
• Every formula is open inside the app, with your own numbers in it. Check the math yourself
• A rank card you can send to the group chat

THE GYM STOPS BEING PAPERWORK
• 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 the app
• Last time's numbers sitting right under today's, so you always know what to beat
• Fully offline. A dead signal in the basement changes nothing
• Machine taken? Swap it in one tap for the same movement, filtered by your gear and your injuries
• Movement demos on the main lifts, plus form cues on every exercise

PROOF, NOT VIBES
• Your strength curve and estimated 1RM on every exercise you log
• PRs detected the second you hit them
• A volume heatmap that shows you 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
• Every set you have ever logged, kept forever, exportable

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 program you can follow without knowing anything. Been lifting for years? You get periodization, volume managed per muscle group, and a push pull legs or upper lower split picked for the days you actually have.

HOW IT WORKS
1. We build the plan
2. You do the work
3. Your character levels up

Your rank today is a fact. Your rank at the end of the block is a decision.
