Sign in to your IJF account or create a new one and you will have the incredible opportunity to be part of a global event in which you can win superb prizes.
You'll have to warm-up a bit to get ready to face young people from all over the world. It's an individual competition, but you can also help your country to qualify to be the best team by nation.
Every Thursday is 'New Challenge Day,’ when we will release two new challenges that we invite you to record with your phone. It's so easy! You accept the challenge, you perform it and post your video. That's it!
You can win amazing surprises like digital golden trophies and personalised golden cards. In total there are 15 trophies and 15 cards to collect.
If you are among the best, at the end of the competition, we will make a random draw to select winners of special bonus prizes.
So, stay tuned, stay strong and fit and have fun.
