Muscle Legends Next Update: Industrial Gym, New Pets & Pet Momentum System Explained

If you've been grinding reps and stacking gems, the Muscle Legends next update is about to shake up your entire gameplay loop. With a brand-new gym, a revamped pet system, and social features that finally let you team up, there's a lot to unpack. Whether you're a seasoned rebirth grinder or just getting your footing, this guide breaks down every confirmed feature, new pet, and mechanic change you need to know before diving in.

What's New in the Muscle Legends Next Update

The latest patch for this popular Roblox fitness experience brings a wave of content aimed at both mid-game and endgame players. From a high-rebirth gym to an entirely new way of boosting your pets, the developers have packed this update with features that change how you train, collect, and compete.

Here's a quick snapshot of the major additions:

The Industrial Gym: Endgame Training Arrives

The centerpiece of the Muscle Legends next update is the Industrial Gym, a training zone designed specifically for players who have hit the 150-rebirth milestone. This isn't just another room with slightly better rocks — it's a full endgame destination that pushes your durability and strength numbers into new territory.

Industrial Rock & Chest Rewards

Inside the gym, you'll find the Industrial Rock, which demands 25 million durability just to interact with. That's a massive jump from previous rocks, meaning only dedicated grinders will be able to tap into this training method right away.

For those looking to build their gem reserves, the Industrial Chest offers 35,000 gems per open. It's one of the more efficient gem sources in the current meta, especially if you're saving up for the new crystal.

New Pets: Industrial Crystal & Pack Additions

No Roblox update feels complete without new pets to chase, and this patch delivers on multiple fronts. The Industrial Crystal costs 7.5 million gems per hatch and contains six new pets with varying rarity tiers.

The Apex Overlord, at a 1% drop rate, is the crown jewel of this crystal. Community reports suggest it offers stat bonuses that rival some of the best pets in the game, making it a serious long-term grind for collectors.

Radioactive & Ultra Titans Packs

Beyond the crystal, two new packs introduce even more pets to your collection:

• Radioactive Pets Pack — Features toxic-themed creatures like the Radio Rat, Sludge Croc, and Nuclear Hydra
• Ultra Titans Pack — Includes heavy hitters like the Biohazard Overlord, Powercore Hound, and Omega Overlord

These packs add nine new pets total, giving players fresh options for both aesthetics and stat optimization.

Pet Momentum: The Glitched Pet Replacement

One of the most significant mechanical changes in the Muscle Legends next update is the introduction of Pet Momentum, which replaces the old Glitched Pets system entirely.

How Pet Momentum Works

The concept is straightforward but requires commitment. When you train with your equipped pets for a continuous 3-hour session, they gain Momentum. This boosts your pet stats by a staggering 50x — though notably, damage stats are excluded from this multiplier.

Important caveat: Momentum resets if you leave the server. You have a 10-minute window to rejoin before your progress wipes. This means planning your training sessions carefully is essential.

This system rewards players who can dedicate solid blocks of time to training, and it shifts the meta away from the old glitch-dependent strategies.

Clans: Finally, a Social Layer

The update introduces Clans, a feature the community has requested for a long time. For 10,000 gems, you can either create your own clan or join an existing one.

Clan Features at a Glance

Clans add a cooperative dimension that was previously missing. By contributing strength and completing quests together, groups can unlock rewards faster than solo players. It's a smart move that should improve player retention and make the grind feel less isolated.

New Eggs Menu & Quality of Life

A small but welcome change is the dedicated Eggs menu inside your inventory. This UI addition lets you manage and hatch your Radioactive pet eggs without navigating through multiple screens. It's the kind of quality-of-life improvement that doesn't make headlines but makes a real difference in day-to-day gameplay.

Known Bugs: The Selling Glitch

No update launches perfectly, and this one has a notable issue. A bug was introduced that allows Pack pets to be sold unintentionally. According to the developers on Discord, this has been patched. However, player experience reports as of August 24th indicate that some users are still encountering the glitch.

Recommendation: Avoid selling any pets from the new packs until you've confirmed the fix is live on your server. If you accidentally sell a valuable pet, contact support through the official Muscle Legends Discord.

How to Prepare for Future Updates

With the Muscle Legends next update setting a clear pattern, here's how you should position yourself for what's coming:

1. Stack gems aggressively — The Industrial Crystal costs 7.5M gems, and clans require 10K to join. Having a cushion gives you flexibility.
2. Push toward 150 rebirths — The Industrial Gym is the new endgame, and getting there early means accessing better training sooner.
3. Plan 3-hour training blocks — Pet Momentum rewards uninterrupted sessions. Set aside dedicated time rather than hopping in and out.
4. Join a clan immediately — The cooperative benefits start adding up fast, and early clans tend to be more active.
5. Hold onto Pack pets — Until the selling bug is fully resolved, don't risk losing rare pulls.

Frequently Asked Question

The update is already live as of late August 2026. All features mentioned in this guide are available in the current version of the game. If you're not seeing the new content, try rejoining a fresh server.

The Apex Overlord from the Industrial Crystal is considered the top-tier pet with a 1% drop rate. However, pets from the Ultra Titans Pack like the Omega Overlord are also extremely competitive depending on your build.

How do I keep Pet Momentum from resetting?

Train continuously for 3 hours without leaving the server. If you disconnect, you have exactly 10 minutes to rejoin before your Momentum resets. Plan your sessions during times when you won't need to leave.
