Expression: "Are you up for it?"


At the top of one advertisement the following sentence was written.

“Are you up for it?”

Could you please explain it to me?


It simply means:

Are you ready for it?

Ready for a new job or ready for buying a new house etc.

Couldn’t it mean:

Are you up to it?


Hi Tom,

Imagine a group of friends are planning a trip that involves say mountain climbing. They could ask another friend if he wants to join them and also take part. Their question would be: Are you up for it?

If the question was: Are you up to it? This would mean they wanted to know whether he was physically capable of doing the trip and climbing mountains.
