Lift a Cube Arms

Arms are the push-up speed gear in Lift a Cube: every arm sets how many seconds one push-up takes, and the developer has not published arm names or prices. Ratings below describe relative throughput observed in gameplay; the calculator accepts any push-up time so you can enter your own.

Last verified:

The core formula: One push-up grants base strength × your material multiplier and takes your arm's push-up time in seconds — so strength per second = multiplier ÷ push-up time. Run your own build through thestrength calculator.

Arm tiers

CStarter armsBase push-up rate everyone starts with
BEarly armsFirst affordable push-up time cut — buy within minutes of spawning
BMid armsFaster reps; pair with Uncommon/Rare material rolls
ALate armsLarge push-up time cut, needed to move past mid-map cubes
SEndgame armsHighest confirmed push-up rate; required for the hundreds-of-millions cubes

Ratings are relative — the developer has not published arm names or prices.

A material multiplier scales the third column directly: a 1.5× Common at 0.6s per rep is ≈2.5 strength/sec. Push-up time upgrades stack with arms — both cut the seconds per rep.

How to get better arms

Arms are bought with Cash at upgrade stations along the map — each zone sells stronger tiers, so walking outward unlocks the shop. Buy order matters: push-up time upgrades first, then the next arm tier, then your next material roll. Full tier ranking on the tier list.

Arms FAQ

What do arms do in Lift a Cube?

Arms set your push-up speed — the seconds each push-up takes. Faster arms mean more push-ups per minute, which multiplies into more strength per second at the training station.

Should I buy arms or roll materials first?

Early on, buy the cheap push-up time and arm upgrades first — they compound with every future roll. Once a chest tier costs more than your next arm upgrade, split Cash between luck rolls and arms.

How do I get better arms in Lift a Cube?

Buy them with Cash at upgrade stations along the map. Each zone sells stronger arms; walking further out unlocks the better tiers.
