What are you up to this weekend?
She's always up to something mischievous
I don't know what they're up to, but it seems suspicious
He's not up to the task of managing such a large project
The children were up to no good in the garden
This movie is too slow for me; I'm not up to watching it
Are you up to a game of chess?
She was up to her ears in paperwork
He's decided he's not up to the challenge of running for office
The team is up to something exciting for the summer festival
I'm not sure yet, maybe see a movie.
Sounds good, let me know if plans change.
