Push it

Hi,

"The doctor cautioned that John was not back at 100% yet, but said John could go back to work as long as he didn't push it."

What does 'push it' mean in the context? Thanks.

. . . as long as he didn't do anything that stressed him, anything that required close to maximum effort.

Best wishes, Clive

Hi Clive,

I'm afraid I don't understand what 'stressed' means here. Could you explain about it? Thanks for your reply.

Hi Clive,

Does 'push it' also mean 'push your luck' in the context?

Thanks.

Hi,
Broadly speaking, yes. Don't push your luck by doing anything that demands a lot of effort.
