The champion Olympian - who just won a silver and two golds in at the Olympic Games in Tokyo - doesn't think his particular type of athleticism will be an advantage on the BBC One ballroom show because moving through water is completely different to strutting your stuff on the dancefloor.
Speaking to BANG Showbiz and other assembled media ahead of the launch of the new series, he said: "It will probably hinder because I’m used to being in the water, I’m not used to being on land and against gravity.
"But hopefully my hips will be quite fluid."
One advantage Adam believes his sports career will give him is that he is used to following a gruelling training regime so he will not be phased by the hours of practice he will be required to do with his professional partner to master his ballroom and Latin routines.
He said: "I'm nervous about all of it. The first few weeks will be quite hard with the training, show, dancing, rehearsing, everything will be quite unsettled, but once I've found my feet a few weeks in then I think I'll be good.
"Swimming training is one of the hardest sports because I'm used to going up and down a lane for four hours a day and going to the gym for two hours, it's quite tedious.
"I’ve trained my mind and body for a long time, so I just hope I can put the hard work to use. I’ve won pretty much every competition I’ve gone into, well in sport anyway, but this is different. I have no idea what to expect.”
Adam, 26, accepted the BBC's offer to compete on 'Strictly' because he felt as though he wanted a break from swimming following his success at this year's Olympics.
He explained: "I felt like I needed to take a bit of time away from swimming because it’s been my my whole life basically."
'Strictly Come Dancing' starts on Saturday 18 September at 7.45pm on BBC One.
