Tumbler Seb has made it onto the team for the World Championships and is off to Tokyo with fellow GB tumbling teammates Bailey, Freddy and Tristan. The pressure is on for Seb as not only is he the youngest member of the team but he has a massive new skill to pull off - the full-in-pike! As the boys arrive in Tokyo, they are hit by a wave of jet lag, but that’s not going to stop them enjoying some sights before things get serious at the competition. Meanwhile, back in the UK, it's judgement day for trampoline gymnast Corey. Corey has been invited to train with the British senior squad in preparation for Olympic selection at the World Championships. However, things haven’t been going quite to plan in training of late and he has been troubled by an injury. This means a visit to the physio is required, for a full assessment to establish if will be safe to carry on training or whether he will have to pull out of the World Championships this year , which will mean his Olympic dream for 2020 is over too.
