Propbet: 10000 pushups in a week

[Let_it_rain]

I made this bet with my mate that by the end of the year (last week of the year) I would do 10000 pushups in a week. It's on the trust system, so he doesn't have too spend a week watching me do [censored] all. I am pretty unfit, not fat just haven't been to the gym for a while. Play sport twice a week and eat healthyish.

With me coming from here:
-do you think i can do it?
-how?

Current game plan, start pushing up and eat healthy so there is less to push up.
