We all know exercise is good for us, but now a personal trainer in Christchurch is putting us all to shame - by doing burpees.
Blair Williamson’s been going at it all day trying to try and break two world records - the first being 7295 burpees in 12 hours.
He's been at it since 8am on Friday, but it's not just to enter the Guinness World Records - it's also for a good cause.
