Olympic star Amy Smith made a splash when she visited children at Antingham and Southrepps Primary School.
The Team GB swimmer had children and staff alike diving into a series of fitness activities.
In a round of fitness circuits, pupils trained like the pros as they did a minute of star jumps and press ups each.
As a cool-down after their hard work, Amy gave an awe-inspiring assembly recounting how she came to win her silver Common Wealth medals and her gold European Championships medals, after being scared of swimming when she began at 7 years old.
She also shared her memories of the London 2012 Olympics, prompting a flurry of questions from children at the school.
Head of School Emma Harding, said: 'Amy truly has inspired and motivated everyone to believe that we can achieve anything if we work hard at it!'
