Kristian Thomas won a bronze medal as part of the UK men's gymnastic team at the London 2012 Olympics.
He took time out from his gruelling schedule to launch the 2012 Glasgow World Cup Gymnastics event, which will be staged on December 8.
The World Cup will be the first major gymnastics competition hosted in the state-of-the-art £113million Emirates Arena, and the first chance to see the top gymnasts on British soil following the Olympic games.
The world's top eight male and female gymnasts will compete for the all-round World Cup title.
The event will feature two mixed sessions, meaning the overall World Cup champions will not be known until the last rotation is complete.
Kristian, 23, from Wolverhampton, took up the sport at the age of five and normally trains between 25 to 30 hours a week. He said: "Competing in Glasgow is always a special experience but this year's World Cup promises to be something else given the move to the new Emirates Arena.
"Having had the chance to look around the venue ahead of its opening this weekend I can see what all the excitement is about.
"It looks incredible and I am really looking forward to getting the chance to test myself in front of a home crowd."
Tickets for the competition on December 8 start at £6 for children, £16 for adults and £40 for a family of two adults and three children. They are available from www.glasgow worldcup.com or by calling 0141 353 8000.
