Lisa beat favourites such as Louis Smith to the top of the scoreboard after the first set of dances, with her Cha Cha earning 30 points from the judges.
"I loved the fact that she has natural rhythm and she really actually dances," Craig said, defending claims that the judges had over marked the energetic routine on Saturday night.
He added: "She has an inner motor. That's fascinating and we were not expecting it all."
But Craig suggested that Lisa may struggle later on in the competition, telly It Takes Two: "I don't know how that will transfer in the ballroom. She'll be able to get her slow, quick, quicks right, but it's her posture and things like that she'll have to watch out for."
Meanwhile, Jerry Hall told the BBC2 spin off series this week that she's been getting advice from her rock star pals, with Bill Wyman choosing the music for her first live dance at the weekend.
She said: "Bill did pick it. I got advice from Bill Wyman, Mick Jagger and Bob Geldolf."
Strictly Come Dancing 2012 continues this Saturday night 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!
