Muscle Legends Rebirth Chart: The Ultimate Glitched Pet Guide (2026)

Master the muscle legends rebirth chart with complete formulas, rock values, and glitchable rebirth lists for every tier from beginner to endgame.

What the Muscle Legends Rebirth Chart Actually Tells You

The muscle legends rebirth chart is the backbone of one of the most powerful progression systems in the Roblox hit Muscle Legends. Whether you're a brand-new player grinding your first few rebirths or a veteran chasing endgame stats, understanding how rebirth counts interact with pet XP mechanics separates the casual lifters from the absolute powerhouses. This guide breaks down every formula, every rock value, and every glitchable rebirth threshold you need to dominate the leaderboards.

Important note: Following the Industrial Gym update, the original glitched pet system was removed and replaced with the Pet Momentum system. The rebirth chart data below preserves the mechanics as they existed and remains valuable for understanding the game's underlying math and progression logic.

How the Rebirth Chart Math Works

The entire muscle legends rebirth chart hinges on two core formulas that determine whether your current rebirth count can trigger a pet glitch. Getting this math right means the difference between wasting hours of grinding and skyrocketing your strength per punch.

The Two Essential Formulas

Formula	Purpose	Expression
EXP Calculation	Find exact EXP per punch at your rebirth	`exp = (rebirths + 20) × rock's value`
Rebirth Calculation	Find exact rebirths needed for a target EXP	`rebirths = (exp ÷ rock's value) − 20`

The key insight? Your EXP per punch must divide evenly into your pet's cumulative XP at a specific level. If the result is a decimal, the glitch won't trigger. If it's a whole number (preferably even), your pet levels up instantly and grants massive stat bonuses per hit.

Rock Values Reference Table

Every rock in Muscle Legends has a fixed multiplier value. Lower-value rocks require significantly more rebirths to reach glitchable thresholds, but they're accessible earlier in the game.

Rock Name	Value	Difficulty Tier
Industrial	40.5	Highest multiplier
Ancient Jungle	16.25	High
Muscle King	12.5	Medium-High
Legends	2.5	Medium
Inferno	1.125	Medium-Low
Mystic	0.75	Low
Frozen	0.375	Lower
Golden	0.2	Very Low
Large	0.075	Minimal
Punching	0.05	Minimal
Tiny	0.025	Lowest multiplier

Cumulative XP Table for Pets

To use the muscle legends rebirth chart effectively, you need to know your pet's cumulative XP at each level. The table below shows levels 1–19 for both Basic and Unique pets.

Level	Basic XP	Basic Cumulative	Unique XP	Unique Cumulative
1	250	250	1,250	1,250
2	500	750	2,500	3,750
3	750	1,500	3,750	7,500
4	1,000	2,500	5,000	12,500
5	1,250	3,750	6,250	18,750
6	1,500	5,250	7,500	26,250
7	1,750	7,000	8,750	35,000
8	2,000	9,000	10,000	45,000
9	2,250	11,250	11,250	56,250
10	2,500	13,750	12,500	68,750
11	2,750	16,500	13,750	82,500
12	3,000	19,500	15,000	97,500
13	3,250	22,750	16,250	113,750
14	3,500	26,250	17,500	131,250
15	3,750	30,000	18,750	150,000
16	4,000	34,000	20,000	170,000
17	4,250	38,250	21,250	191,250
18	4,500	42,750	22,500	213,750
19	4,750	47,500	23,750	237,500

Other pet rarities follow the same pattern. Starting XP per grade scales as follows: Basic (250) → Uncommon (500) → Rare (750) → Epic (1,000) → Unique (1,250). Add the same starting amount to the previous level's requirement to calculate any rarity's cumulative XP.

Complete Glitchable Rebirth Lists by Rock

This is where the muscle legends rebirth chart becomes your progression roadmap. Below are the community-verified glitchable rebirth counts for Unique pets across every rock type. Each entry shows the rebirth count and the stat multiplier per punch in parentheses.

Muscle King Rock (Best for F2P Players)

Rebirth	Stats/Punch	Rebirth	Stats/Punch
80	+5	4,480	+45
280	+10	5,480	+50
580	+15	6,580	+55
980	+20	7,780	+60
1,480	+25	9,080	+65
2,080	+30	10,480	+70
2,780	+35	11,980	+75
3,580	+40	13,580	+80
		15,280	+85
		17,080	+90
		18,980	+95

Muscle King rock is the go-to for free-to-play players because it offers the lowest rebirth thresholds for maximum stat gains. Community reports confirm that glitching on Muscle King rock only works when you're standing outside the ring.

Legends Gym Rock (Endgame Standard)

Rebirth	Stats/Punch	Rebirth	Stats/Punch
480	+5	22,480	+45
1,480	+10	27,480	+50
2,980	+15	32,980	+55
4,980	+20	38,980	+60
7,480	+25	45,480	+65
10,480	+30	52,480	+70
13,980	+35	59,980	+75
17,980	+40	67,980	+80
		76,480	+85
		85,480	+90
		94,980	+95

The Legends rock is where serious players spend most of their time. At 94,980 rebirths, a Unique pet delivers +95 stats per punch — the maximum possible multiplier.

Ancient Jungle Rock (Low Rebirth Alternative)

Rebirth	Stats/Punch	Notes
56	+5	Add 15 EXP before using
60	+5	Add 1,200 EXP at level 2 first
208	+10	Add 45 EXP before using
440	+15	Add 25 EXP before using
748	+20	Add 20 EXP before using
14,580	+95	Add 250 EXP before using
14,592	+95	Add 55 EXP before using

This rock is ideal for players who want decent multipliers without grinding hundreds of thousands of rebirths.

Higher-Tier Rocks (Inferno, Mystic, Frozen, Golden, Large, Punching, Tiny)

For rocks beyond Legends, the rebirth counts climb dramatically. The Tiny rock — despite having the lowest value at 0.025 — reaches its max glitchable threshold at a staggering 949,980 rebirths. The Inferno and Mystic rocks offer mid-ground options for players with millions of rebirths who want alternatives to the Legends grind.

All lists were compiled by community contributors PURPLE SMILER and LLordAleex through extensive player testing.

Three Methods to Execute the Glitch

The muscle legends rebirth chart means nothing without knowing how to actually trigger the glitch. Here are the three proven approaches.

Method 1: Treadmill (Beginner — 0 to 79 Rebirths)

This is the simplest entry point. Head to the beach and find the two +1 XP treadmills located in front of the Tip #3 sign near the statue.

Step-by-step:

Equip any pet and exercise until it's close to leveling up
Switch to the 1 XP treadmill and stop when your pet needs exactly 1 XP to level
Get off the treadmill and wait 5 seconds
Start running on the correct treadmill — your pet should begin glitching

Keep in mind:

Works with any pet rarity, any rebirth count, and even auras
Rarer pets yield better results
Stats increase by roughly +0.85 strength per second
The glitch disappears if you quit, leave, or disconnect

Method 2: Punching Rock (Intermediate — 80+ Rebirths)

This is where the rebirth chart becomes essential. You need an even-numbered rebirth count that satisfies the EXP formula for your chosen rock.

Key requirements:

Rebirth count must produce a whole-number result when divided into cumulative XP
Best rocks: Muscle King, Legends, Tiny Island, Punching, and Golden
Players typically reach around 5,000 stats per pet using this method

Once you've glitched pets at 80 rebirths, you can "boost" to higher glitchable thresholds. The recommended progression paths vary based on your internet stability and device performance.

Method 3: Advanced/Endgame (18,980+ Rebirths)

This is the method pro players use to reach trillions of strength. At 18,980 rebirths on Muscle King rock, a Unique pet gives +95 stats per punch. At 94,980 on Legends rock, you get the same maximum multiplier.

Optimal boosting paths based on connection quality:

Connection Quality	Recommended Path
Poor	1,480 → 2,080 → 2,780 → 3,580 → ... → 18,980 (gradual steps)
Fair	2,080 → 4,480 → 7,780 → 10,480 → 13,580 → 18,980 → 32,980 → ... → 94,980
Excellent	3,580 → 10,480 → 18,980 → 45,480 → 94,980
Autoclicker + Godlike Internet	4,480 → 18,980 → 94,980 → 210,980

Practical Tips for Using the Rebirth Chart

Always verify with the EXP formula first. The rebirth formula doesn't always return exact results for every rock value. If you get a decimal, that rock won't work at that rebirth count.
Use an alt account for risky boosts. If your WiFi is unstable, glitching on an alt protects your main account from losing progress.
Avoid server maintenance windows. Getting caught mid-rebirth during maintenance can break your glitch run.
Unique pets are always worth the grind. The +5 fixed stat per level (maxing at +95) makes them vastly superior to lower rarities.

Frequently Asked Questions

What is the muscle legends rebirth chart used for? The rebirth chart helps players identify exact rebirth counts where their pet XP gain divides evenly into a pet's cumulative XP, triggering a glitch that grants massive stat bonuses per punch.

Which rock is best for beginners using the rebirth chart? Muscle King rock is the best starting point because it has a high multiplier value (12.5) and reaches maximum efficiency at just 18,980 rebirths, making it ideal for F2P players.

Do glitched pets still work in Muscle Legends? The original glitched pet system was removed after the Industrial Gym update and replaced with the Pet Momentum system. The rebirth chart remains useful for understanding the game's progression math.

How do I know if my current rebirth is glitchable? Use the formula exp = (rebirths + 20) × rock's value, then divide each cumulative XP level by that number. If any result is a whole (non-decimal) number, your rebirth is glitchable at that pet level.
