In +1 Strength for Eggs, the Roblox tycoon from Crazay ASMR, dumbbells are the single biggest lever on how fast you train. Each one raises your strength per second, which lets you smash through tougher walls, reach higher-rarity zones, and haul rarer eggs back to your base. Upgrading to a better dumbbell is the fastest way to speed up every part of that loop.
Quick answer: There are 43 dumbbells. The cheapest is the Wood Dumbbell, handed to you for free at the start, and the most expensive is the Celestial Void Star Dumbbell at $2.62Qi.
How dumbbells work in +1 Strength for Eggs
You buy dumbbells from the Dumbbells shop, and the equipped one sets your training rate. The rate is shown as a per-second figure, so a dumbbell listed at 15/s adds 15 strength each second while you swing it or use an auto-train pad. Higher strength scales your character and lets you break walls with more hit points.
Most dumbbells are bought with in-game cash, which your hatched animals generate over time. Many of them also carry a Robux price in the shop if you want to skip the grind. Rebirth resets your current strength to zero but keeps every dumbbell you have already unlocked, so purchases are permanent.
The equipped dumbbell stays with you through a rebirth, so buying a strong one before stacking rebirths lets you clear each strength requirement in just a few swings.
Early-game dumbbells (Common, Rare, Epic)

Mid-game dumbbells (Legendary, Mythic)
From the Anvil onward, training rates jump into the tens and hundreds of thousands per second. This stretch is where income from stronger animals starts paying for much bigger upgrades.
| Dumbbell | Rarity | Cost | Power |
|---|---|---|---|
| Anvil | Legendary | $61.25M | 18.5k/s |

High-tier dumbbells (Secret, God, OG, Divine)
These dumbbells run from the trillions into the quadrillions in cost. Power gains per step shrink here, so each upgrade buys a smaller percentage boost even as the price climbs steeply.

|---|---|---|---|
| Frosted | Secret | $875B | 250k/s |
| Meteorite | Secret | $1.4T | 270k/s |

| Bee | OG | $35T | 422.5k/s |
| Toxic | Divine | $87.5T | 446k/s |
| Time | Divine | $525T | 470k/s |
| Hacker | Divine | $1.75Qa | 500k/s |
| Dumb | Divine | $6.12Qa | 520k/s |
Endgame dumbbells (Transcendent, Ancient, Celestial)
The final run tops out at the Void Star, the strongest and priciest dumbbell in the game. Reaching this bracket usually relies on stacked rebirth multipliers and high-earning animals funding the quadrillion-tier prices.
| Dumbbell | Rarity | Cost | Power |
|---|---|---|---|
| Portals | Transcendent | $14Qa | 550k/s |
| Blackhole | Transcendent | $26.25Qa | 592k/s |
| Quasar | Transcendent | $52.5Qa | 635k/s |
| True Ban Hammer | Ancient | $91.87Qa | 700k/s |
| Noob | Ancient | $122.5Qa | 724k/s |
| Thousand Kilo | Ancient | $175Qa | 760k/s |
| Mega | Celestial | $1.5Qi | 800k/s |

| Void Star | Celestial | $2.62Qi | 875k/s |
Which dumbbell to prioritize
The simplest rule is to buy the most powerful dumbbell your current cash can afford, since a faster training rate speeds up every wall break and egg run after it. Early on, the Common and Rare tiers are cheap enough to climb quickly. The gap between purchases grows fast once you pass the Mythic tier, so lean on animal income and rebirth money multipliers to keep up.
You can confirm an upgrade worked by checking the equipped dumbbell in the Dumbbells shop and watching your strength-per-second figure rise to match the new rate. If a dumbbell is still listed with a purchase price, it is not yet owned or equipped.
