IT HAS a reputation for being one of the hardest exercises to do and has the ability to make grown men break - the burpee.
And now one Grafton business is using the pain-inducing movement to help fundraise for Camp Quality - but it won't just be a set of 10 or 20 or even 30.
The Burpee 500 fundraiser calls on participants to travel 500m one burpee at a time - jumping forward instead of straight up in the air until they reach the 500m mark.
Shaun Davison of Hybrid Fitness - which will host the fundraiser - said the difficult exercise was chosen was because of the suffering children with cancer face.
"The kids are suffering so we want to suffer as well," Mr Davison said.
"If we can put ourselves in their shoes for a short period of time, mentally and physically.
"We want to show the kids we support them and want to help with their battles with cancer so we are trying to put ourselves in a state that these kids face every day; suffering but still being posi- tive and having fun."
Mr Davison said those not quite ready for the gruelling challenge could still do their bit.
"We are looking for people to donate, sponsor, and participate. We want local businesses to either donate or put a small prize towards a raffle for the event," he said.
Mr Davison said a previous fundraiser for the children's ward at GBH raised over $7500.
"So if we can get the same amount of support again it will be fantastic," he said.
The event is at Hybrid Fitness on April 13.
