Personal trainer Alice Liveing visited an unusual office where workers are encouraged to play ping pong, use punch bags and cycle around their desks as a way of beating the sedentary lifestyle.

The author of the 'Clean Eating Alice' cookbooks said she was "incredibly interested" to find a way for office workers to stand up and move around during their work day.

Public Health England guidance says workers should stand up for at least two hours a day in the office.

Dr Nick Knight explained the dangers of sitting down all day.

"Sitting all day increases our risk of conditions like cardiovascular disease and type 2 diabetes," he said.
