Weights are the items you train with. The description tells you to lift them for Muscle and to open chests for rare weights that gain even more. The only weights that can be named today are four dev products. No product shows a Muscle number.
The four named weights
Names are copied from the visible catalog. Op weight is spelled that way on purpose.
| Product | Listed price | Rarity word in the name |
|---|---|---|
| Common Weight | R$1 | Common |
| Uncommon Weight | R$3 | Uncommon |
| Op weight | R$10 | Op, with no extra tier label |
| Rare Weight | R$29 | Rare |
The price rises in that order. That ladder is not a measured Muscle ranking. The performance rule that is actually stated is qualitative: rarer weights grant more Muscle. Op is not a standard rarity word, so do not read it as stronger than Rare just because it says Op.
The same snapshot sat inside a catalog of 28 dev products priced from R$1 to R$499, with 12 products visible. More weight-named products may exist outside that view. Nearby products that are not weights include 1.5X Muscle, 2X Muscle, 4X Muscle, and Instant Muscle I.
How you get one
- Chests. Opening a chest is the roll. The description calls out rare weights as possible results and ties them to extra Muscle. It does not say where chests are, what they cost, or the chance of each tier.
- The Robux store. The four products above were listed for direct purchase. Nothing says a purchased tier is identical to a chest-rolled weight of the same name.
No free route to a specific named weight is documented. Whether a rolled weight is stored, auto-equipped, or swapped in is also unpublished. If your roll screen prints percentages, those numbers outrank any fan chart. You can type a percent you can see into the chest roll chance tool. Leaving the chance at 0 keeps the tool from inventing a rate.
Which weight to use
Equip the rarest weight you can actually obtain. If you want the top of the documented ladder without rolling, Rare Weight at R$29 is that purchase. If you would rather not spend, roll chests and replace your weight when a rarer result lands. Rankings that claim Op beats Rare by a hidden stat, or that Rare grants twice the Muscle of Common, add numbers the game has not printed.
V.I.P Roll [PERMANENT] was listed at R$29 beside these products. Nothing published says it changes weight odds. Item pages for each tier are under Weights.
