We're doing the TEN MINUTE BURPEE CHALLENGE to help raise money for a pioneering cancer treatment in New York for five year old Bibi.

Take part and then tag ten friends to take part too!

Here's how to take part:

1. Get Ready to Burpee!

The challenge is to see how many burpees you can do it ten minutes. It can be 10, 20, 50 or 100! Burpees are the devil so any amount is amazing.

2. Donate, share and get sponsored

Share your challenge far and wide with friends, family, strangers, celebrities, royalty...

You can share this page or join the team and set up your own page here:
