Beth Tweddle is hoping it will be third time lucky in her final bid for Olympic gold but revealed she might only compete on one piece of apparatus.
The three-time world champion underwent knee surgery in April and missed out on the European Championships as a result, and at the grand old age of 27, the gymnast admits she can only realistically mount a medal challenge on the bars.
"I'm definitely going to be on bars and I've got floor up to a standard where hopefully I can be part of the team," Tweddle told Press Association Sport. "I can't contend for any (floor) finals so it will all depend on what the team need me for but I am fit to do floor if they want me."
However, Tweddle, who also has six European and seven British titles to her name, refuses to pile pressure on herself to win a medal in her third and final Games after narrowly missing out in fourth place in Beijing and not making the final in Athens eight years ago.
"If I can come away having done the best routines I can - if that comes away with a medal, then so be it. If it doesn't then I've got a lot more to look back on in my career," Tweddle said.
"A lot of people are alluding to it that if I don't pick up an Olympic medal it will be a failure. If I start thinking like that my whole career is kind of a failure instead of thinking how much I have achieved.
"I did gymnastics because I loved it and I never thought I would have achieved what I have done. To get to an Olympic Games is a massive achievement and I would love to finish it with a medal but I've got a lot to look back on if I don't."
In contrast with Tweddle, 15-year-old Rebecca Tunney will compete in her first Olympics and will be Team GB's youngest member.
The City of Liverpool gymnast has impressed in her first year of senior competition and was named in the squad alongside Tweddle, Hannah Whelan, Jenni Pinches and Imogen Cairns. Tunney came out on top in all three Olympic trials and proved she could handle pressure on the big stage with a composed performance at this year's European Championships.
She said: "It's definitely been the most amazing year of my life this year. I've had so many competitions leading up to the Olympic Games but I've had a good year and a good run so far."
