How to get huge in Gym Sim.
Everything you need to pass my 455 lb deadlift record, then keep going. Upgrades, hustles, gyms, trips, rebirths and the rankings, explained.
The basics
RTX Gym Sim is a free tap-to-lift idle game. You start in your bedroom with an empty bar. Every tap is a rep, and every rep earns gains. Gains are the main currency: you spend them on upgrades that make each rep worth more, or that earn gains on their own every second.
As your total gains grow, your deadlift max goes up, your physique changes (Skinny → Lean → Athletic → Jacked → Mass monster), and you unlock new ways to make cash. Cash buys gyms, outfits and trips around the world.
Your progress saves automatically on your device. You also earn gains while you're away (up to two hours of “sleep” gains), so come back and collect.
Upgrades
There are two kinds of upgrade, and you want both:
- Per rep (protein shake, chalk, straps, creatine, belt, knee sleeves…) make every tap worth more. Great early, when you're tapping a lot.
- Per second (8 hours of sleep, 10k steps, gym buddy, meal prep, sauna, personal chef…) earn gains even when you're not tapping. These win the long game.
Every level makes the next one cost more, so spread your gains around instead of maxing one thing. The special RTX Coaching upgrade multiplies everything by ×1.15 per level, and it stacks. It's one of the best buys in the game.
Real life works the same way: protein, sleep and daily steps are the boring basics that make everything else work.
Hustle: making cash
Hustles are buttons you press for cash and followers. Each one has a cooldown.
| Hustle | Unlocks at | Cooldown | What it gives |
|---|---|---|---|
| Post a gym TikTok | Start | 15s | Cash + followers. Pays more the more followers you have. |
| Film a YouTube vlog | 225 lb deadlift | 45s | Bigger cash and follower bump. |
| Compete at a meet | 315 lb deadlift | 90s | Pays more the heavier you pull. |
| Brand promo post | 1,000 followers | 60s | Big cash that scales with followers. |
Later you also earn cash every second from clients you pick up on trips, from sponsors, and from your follower count once you pass 10,000 followers.
Gyms
Each gym multiplies all your gains. Buying a better gym is usually the biggest single jump you can make.
| Gym | Cost | Gains boost |
|---|---|---|
| Bedroom | Free | ×1 |
| Garage gym | $400 | ×1.15 |
| Commercial gym | $3,000 | ×1.35 |
| Powerlifting meet | $15,000 | ×1.6 |
| Muscle beach | $60,000 | ×2 |
| Space station | $300,000 | ×3 |
Travel
Trips cost cash and take you around the world to meet characters, land fictional sponsors and pick up coaching clients. What you say matters: be confident and respectful and people (and brands) like you more. Each trip can be taken more than once.
| Trip | City | Cost |
|---|---|---|
| Times Square | New York | $1,500 |
| Eiffel Tower | Paris | $4,000 |
| Muscle Beach | Los Angeles | $12,000 |
| Shibuya Crossing | Tokyo | $30,000 |
| Burj Khalifa | Dubai | $90,000 |
| The Colosseum | Rome | $250,000 |
If you've joined the rankings, you can type your own replies to the people you meet. They're AI characters, so say whatever you want and see how they react.
Closet
Spend cash on tops, bottoms, shoes and extras to dress your lifter, and change their look (build, skin, hair, eyes and more). Outfits are cosmetic, and you keep them through rebirths.
Rebirth
Once you earn 25 million gains in a run, you can rebirth. It resets your gains, cash, upgrades, gyms and clients. In return you get a permanent ×2 on everything, and it stacks with every rebirth. You keep your look, closet, sponsors, rank and 10% of your followers.
Each rebirth needs 8× more gains than the last one, but your multiplier doubles each time, so every run is faster than it looks.

Rankings, chat and DMs
Pick a name to join the global rankings. You can be ranked by deadlift, followers, income or rebirths. You get a recovery code (and can add an email and password) so you can keep playing on another device.
Joining also unlocks the live chat, private messages and AI conversations on trips. Chat is mostly unfiltered, but a few rules keep it fun for everyone:
- No slurs or hate toward anyone's race, religion, sexuality, gender or disability. Those words get blocked automatically.
- No links in chat (stops scams and spam).
- No harassment, threats, sexual content or sharing anyone's personal info.
- Don't cheat the leaderboard. Scores that jump faster than the game allows get trimmed.
Players who break the rules can be muted or removed. You can block anyone and turn off DMs whenever you want.
Pro tips
- Buy 8 hours of sleep early. It earns while you're offline, and offline gains add up.
- Keep TikTok on cooldown. It's free cash from the very first second.
- Garage gym first. $400 for ×1.15 on everything pays back fast.
- Level RTX Coaching whenever you can. It multiplies every other upgrade.
- Go to New York as soon as you hit $1,500. Your first sponsor and clients start your cash income.
- Rebirth as soon as you can. A ×2 for everything beats grinding the same run.
