Beat a record.
Knock out
a monster.
One Gym Man is a workout tracker where your personal records do the fighting. Every monster is a real fitness standard — 30 push-ups, a 185 lb bench, a sub-30 5K — and its health bar is the gap between you and it. The only way to land the knockout is to actually get stronger.

What would your bench knock out?
Type your best bench press set. The app turns it into an estimated one-rep max, and every Push monster that number beats goes down. This is the same ladder the app ships.
Estimated 1RM 158 lb
Push monsters also fall to push-ups, overhead press or dips — every lane has several paths, so any training style can climb.
How it works
Train. Set a PR. Land the KO.
A serious training log on the way in, a knockout on the way out.

Records deal damage
Each monster's health is your gap to a real standard. Only a genuine personal record shrinks it — no grinding, no gear, no gacha.

Share the knockout
Every KO makes a card for your feed or the group chat, with a link that dares your friends to take the same monster down.
The ladder
Sixty monsters. Wolf to God.
Push, Pull, Legs, Core and Cardio each climb ten threat tiers, and every tier has a boss that falls when three lanes clear it.
Power only grows with real feats
Your Power Level adds up every tier you clear. It can't be bought, grinded or faked by logging a lot of easy sets.
Every style has a path
Each monster falls to any one of several feats — barbell, dumbbell, calisthenics or cardio — so you train your way.
Stats that mean something
Records for every exercise, training-day and consistency charts, weekly volume and estimated 1RM trends.
Daily challenge

100 push-ups, 100 sit-ups, 100 squats and a 10 km run. Every single day. It's the legendary hero training plan — the one rumored to cost you your hair. Nobody starts at 100, so it's five stages of the same four moves, logged with one tap.

Questions
The short answers.
How does a monster take damage?
Each monster sits at a real fitness standard — 30 push-ups, a 185 lb bench, a 5K under 27:30. Its health bar is the gap between your personal best and that standard, so it only shrinks when you set a personal record: a heavier estimated one-rep max, more reps, a longer hold, a longer distance or a faster time. Cross the line and it's a knockout.
I'm a total beginner. Is this for me?
Especially. Tier 1 is 5 push-ups, a 15-second plank or a half-mile run. The baseline test during setup knocks out everything you can already do, so you start with a win and a clear next target.
What can I log?
38 exercises across Push, Pull, Legs, Core and Cardio — barbell and dumbbell lifts, calisthenics, holds, runs, rides, rows and swims — plus your own custom exercises, in pounds or kilograms and miles or kilometers.
Is it free?
Yes. Logging, all 60 monsters, the baseline test, the Hero Regimen, streaks and KO cards are free, supported by a small banner on the main tabs and an occasional full-screen ad after a finished workout — never during one. One Gym Man Pro is a one-time unlock — no subscription — that removes ads and adds full progress charts, unlimited routines and custom exercises, and premium KO card styles.
Do I need an account?
No sign-up, no login. Everything lives on your phone and works offline — export a backup file any time and import it on a new phone.
I used the old version. Is my history safe?
Yes. Version 2.0 converts your logged workouts automatically and replays them through the new system, so the monsters you've earned fall on day one — and your old victories stay on your trophy wall.
Can't I just log fake numbers?
Sure — and you'd be lying to a monster only you and your friends can see. There's no global leaderboard on purpose. The only opponent that matters is last month's you.
The monsters aren't getting stronger.
You are.
Free. No account. Tier 1 is a wet paper bag with a face — see how far you get.
