A professional boxer by trade, Michael said he was blindsided by Adriana's dedication to ping back into shape for this year's show.

'Adriana has the mind of a fighter. She's extremely competitive, she always likes to be at the best of her game,' he said in the joint interview.

'So I don't feel that it's a challenge for me at all. I put the challenge out there and she always accepts it.'

The right fit: Adriana said that when she discovered boxing, she knew it was the right exercise for her

The founder of AeroSpace, Michael said his regime is perfect for getting an all-around toned physique.

'A lot of other exercises, especially cardio exercises, teach you how to run, dance and cycle, so you're using your legs. With aero boxing, you're using your core and your arms,' he said.

'So you're using your upper body to get a great cardio workout, but you also get the great abs, and the beautiful arms, and everything else to go with it.'

Meanwhile, Adriana took the opportunity to congratulate Kate Middleton on her pregnancy.

Last year she had told the Telegraph that her pre-show planning involved months of training, upping to twice-daily workouts in the weeks before the lingerie showcase.

She said she has a protein-heavy liquids-only diet for nine days in the run-up to the finale and drinks a gallon of water each day.

In the final stretch, for 12 hours before the show, she would stay away from liquids altogether, explaining to the newspaper: 'No liquids at all so you dry out, sometimes you can lose up to eight pounds just from that.'

Following the interview, Adriana raised eye! brows far! and wide for condoning extreme dieting.

The model and mother was quick to dismiss the gruelling regime as nothing more than a 'misunderstanding.'

Speaking with E! Canada, the Brazilian model urged impressionable teenage girls to ignore her stringent preparations.'Those teenagers out there, don't go starving yourself or only drinking liquids... Don't do that please.'

Instead, she made a show of flashing her Starbucks coffee and cake: 'I have my Starbucks coffee right there,' and said that her intense diet comments were simply 'a misunderstanding.'

She also said it is something she does not adhere to throughout the year.

'It's not that I do crazy diets throughout the year. I just do it for this particular thing. After this show, I become normal again!' she told the Canadian network.

'I know it's very intense but...I just have an athlete's mind and I appreciate doing this thing.'
