The Olympian struggled with the first live show last weekend, forgetting the routine to her cha cha and landing bottom of the leader board.
And the London 2012 champ is determined it won't happen again tonight, spending up to 10 hours a day with Brendan Cole in rehearsals.
"You would think she’s training for another Olympics!" a source told the Daily Star today. “She is determined to do the best she can.”
The 32-year-old added: “I don’t want to leave.
“They might have to physically turf me out as I’m enjoying it so much.”
Strictly Come Dancing 2012 continues tonight on BBC One, with all of the celebs performing their second dance.
The first results show will follow on Sunday, with one celeb getting the boot and a performance from the Scissor Sisters.
