Getting Started in Void Muscle HYDRA
First session checklist: HUD, three stats, codes, and a pet that is not a trap.
Void Muscle HYDRA is a free Roblox muscle simulator from Rebloxian Studios. You spawn small, you click a machine, you get bigger, you rebirth, you hatch something with too many heads. This page is the first hour without the usual trap of punching the starter dummy until you hate the genre. For every button on the chrome, use HUD and controls.
Play the live experience here: Void Muscle on Roblox. Then keep this tab open next to the codes hub and the pet tier list.
The HUD in one minute
Top bar: Strength (the big number), Gems (blue), Gold Coins (yellow). Right stack: Claim, Ultimate, Plus, Packs, Fortune, Quests, Codes. Left stack (localized in some servers): Stats, Ascend, Rebirth, Shop, Items, Trade, Index. Bottom: weather, multiplier chips such as 4x Rebirth / 3x Strength / 2x Gems, and the lift / camera buttons.
If you cannot see Codes, close Items. If chat ate the stack, hide chat. Mobile players should rotate landscape — a portrait keyboard will eat the Codes field, which is how people “redeem” into world chat.
First ten minutes
- Claim + Fortune + Codes. Do the free lanes before you lock onto a machine. How to redeem and group rewards cover the clicks. Join Rebloxian Studios and rejoin the server.
- Sit the starter Strength machine. Strength is the rebirth currency. Durability and Agility matter, but the first rebirth is a Strength check. Do not bounce between three tools every ten seconds.
- Open Items and equip any join pet or code pet. Even a Cursed Void Bunny with a few thousand Strength beats empty slots. Pet slots are limited; the +2 Pet Slots pass is ranked on the gamepass tier list.
- Spend starting gems on an egg, not on a trail. Read pets and eggs before you smash the nearest crystal.
- Ignore PvP until you have a rebirth. Getting flung is funny; losing a training cycle is not.
The three stats
Void Muscle tracks Strength, Durability, and Agility (the HUD may label Agility as Speed). Strength buys rebirths and size. Durability keeps you on a machine when someone punches you and feeds some gym gates. Agility is movement and a few later rooms. A healthy early split is roughly 70 / 20 / 10 until your first rebirth, then you rebalance using stats and builds.
Gamepasses exist for x2 Strength, x2 Durability, x2 Agility, 2x Rep Speed, x2 Gems, and 3x Hatch. None of them are required for the first hour. If you will buy one thing later, it is usually 3x Hatch or x2 Strength — not the joke pass named “ultra massive free robux.”
First rebirth
Rebirth resets the visible grind and pays a multiplier. Do it as soon as the button is affordable, not after you “feel ready.” Sitting on a starter machine with a huge Strength pile is how people fall behind the Infernal Gym crowd. The full timing lives in rebirth and training and the rebirth planner.
After the first rebirth, walk the lobby for a newly unlocked gym instead of returning to the same bench. Leaked and live gyms are tracked on new gyms and ranked on gym tiers.
Pets, Hydra, and crystals
You will see Super Solin Hydra in thumbnails on day one. You will not own it on day one. Hydra-line pets are evolved, inventory-tagged units with Strength, Durability, Damage, Gems, and Rebirth lines. Chase them with the Hydra guide after you understand eggs.
The Void Crystal is a limited secret crystal, not the shop default. When chat screams “crystal,” open how to get the Void Crystal rather than spending Gold Coins on a cosmetic. Gold Coin order of spend is its own page: Gold Coins.
Controls worth learning
Movement is standard Roblox. Interact with a machine to start reps. The lift button on the bottom bar is your auto-rep when you have the pass or a temporary boost. Camera (eye icon) helps on crowded Infernal pads. Shift-lock helps on mobile less than landscape does.
If a script promises auto-lift and auto-rebirth, read script safety first. The DATA FIXED title exists because inventories already broke once.
First-session checklist

Then come back to this hub via Guides when you hit the Hydra wall.
