Taking exercise at work may hold great benefit for employees as everything is done on a computer leading to restricted movement, a consultancy says.

Everything from emailing and filing to organising their social life and booking a sandwich for lunch is done on a computer, according to System Concepts.

Recent research by the University of Bristol showed exercise during the working day helped re-energise and improve concentration, made people feel calmer and particularly assisted with problem solving.

Tom Stewart, joint managing director of System Concepts, said the trouble these days is that there is very little that is not done on the computer.

"Workers are effectively locked to technology, but our bodies are designed to move," he added.

The research also showed employers could consider installing bike racks, allowing more flexible work patterns or starting up a lunch time walking group to encourage workers to be more active.
