British gymnast Beth Tweddle has revealed that she is still undecided on which routine to opt for in the Olympic Games.

The 27-year-old, who has three world titles under her belt, is determined to clinch her first Olympic gold medal as she prepares for her final participation in the Games.

"I've tried out a couple [of routines]," Sky Sports News quotes Tweddle as saying. "Both of them I'm really happy with, so I've got to leave it up to my coaches to decide what they want me to go out with.

"I think the judges wonder what I'm going to do when I'm on the bar because I do have two different versions of the routine, but we're just going to play it safe with the team and see which one they need me to do.

"Obviously if I progress then I can make the decision. Every day I've been doing both routines so it's not like it will be a major issue. I have competed [with] both at different competitions."

Tweddle has two routines with difficulty scores of 7.0 and 7.1 to choose from.
