English to Spanish Other Slang

Hi,

I'm working on a videogame translation set nowadays in the US and there is a character that complains that someone is "commandeering a treadmill" at the gym.

I don't quite understand what does "commandeering" mean in this context and how to translate it into Spanish.

CONTEXT:

"That means: No holding your rolled-up umbrella sideways so it's poking passersby; no commandeering a treadmill during your gym's rush hour for 55 minutes."

"Does a gym treadmill time limit apply when there are open treadmills? NO! ..... Dont feel guilty about commandeering a treadmill and using it."

My guess is that this person is staying in the treadmill for too long and keeping it for himself rather than just spending a limited time and them leaving it for another person to use it. That could be "está acaparando la cinta de correr".

Could you please confirm that my understanding is right or propose other options?

Thank you!
