If you haven't heard, this Sunday is kind of a big day on the 2018 sporting calender - Kiwi Joseph Parker fights Brit Anthony Joshua in a Heavyweight champion unification bout.
In the lead up, Parker revealed he's had surgery on both elbows last November.
But his team says the WBO heavyweight champion is now at "maximum speed and power".
So in the spirit of things, the Seven Sharp hosts thought they'd test the power of their own punches: Hilary vs Jeremy.
To show them how it's done young Kiwi heavyweight Patrick Mailata stepped up as trainer.
So who came out on top? Check out the video above to find out!
