On Tuesday, the 28-year-old Olympic uneven bars bronze medallist from London 2012 was voted onto the FIG Athletes' Commission.
The first British woman to win Olympic, European or World Championship medals, Tweddle is considered to be the country's most successful gymnast ever.
Also a three-time Olympian, she retired in August, a year to the day following her London 2012 success, but will remain involved in gymnastics.
Tweddle is one of six on the FIG Athletes' Commission tasked with continuing the development of the sport and insists she will work just as hard outside the gym as she did in it.
"It's a huge honour to be voted in by fellow gymnasts and I'm determined to work as hard as possible to help create the best environment for them to excel in the future," said Tweddle.
"I have a lot of experience of major events across the world and know how important it is for the conditions and processes to be right for the gymnasts in order for them to have the best competitions.
"I look forward to working with the current gymnasts, taking on their ideas and feeding them back to FIG."
