Thanks.

Which one is the impossible one between them:
I have not worked out since two months.
I did not work out since two months.

I am assuming the the second one, with did, is the impossible but the first is possible?

Both. "since two months" is the impossible part.

Oh really! I thought that since has the same meaning as 'for', as in from two months ago till now. What about it I include the word 'ago'? Would that still not be possible in the present perfect one?

That's possible with the present perfect, but it's an inferior solution. The most usual way is to name the month. "since January", "since August", etc.

Ok. I am just curious, could you explain why it is possible with naming the month but not using 'since'?

Also, are these correct:
It has been a long since we have last met.
It has been a long time since we last me.

Specifically, is it possible with and without 'have'?

Why ask if you don't read the answer? Let me repeat what I wrote about the combination of "since" and "ago".

That's possible with the present perfect, but it's an inferior solution.

Note that I didn't say it'

Sorry for the misunderstanding. I meant to ask why is 'since' without 'ago' impossible, and I understood what you wrote regarding the combination of 'since' and 'ago'.

Thanks again for your help!
