Kate's personal trainer recently revealed the grueling workout that got the blonde beauty into shape for the Sports Illustrated Swimsuit Issue.

The supermodel embarked upon a routine that saw her exercise up to two times a day, for nearly two hours at a time.

Trainer David Kirsch told People how he also put the 2013 cover girl on a strict diet that banned her from consuming alcohol, sugar, bread and other processed carbs.

He described how they started working together in August in preparation for the December photoshoot, and did two sessions a day for the first two weeks.

Afterwards, Kate worked out five-to-six days a week for up to two hours at a time.

'[She did] boot camp circuit training mixed in with cardio,' Mr Kirsch said. 'Running, rowing and the elliptical.'

The six key areas they worked on were her legs, inner thighs, hips, butt, abs and arms, he revealed.

'Anything that shows when you're wearing a bathing suit,' he explained. 'Which is… everything!'

Diet was key too, he continued: 'She followed my ABC's — no alcohol, bread or processed carbs – and no sugar — 24/7 with no cheat days.'

In addition, she did a seven-day cleanse twice a month, which saw her replace most meals with a shake regimen.

Most remarkably, perhaps, is that Kate apparently didn't complain at all about the strict plan.

It seems her challenges were only just beginning when it came to the day of the shoot. Earlier this month, she revealed that she suffered from frostbite after shooting her second Sports Illustrated cover in Antarctica.

The assignment saw her strip off to a tiny white string bikini on the shores of the South Pole, where the average high is around -49 degrees Fahrenheit.

Describing the effects the sub-zero weather had on her body she told the Today show: 'When I came back, I was like losing hearing and eyesight because my body was shutting down, it was working so hard to keep me warm...

'Obviously, the pictures now, it's incredible. I can't believe we were all able to accomplish that.'
