Car workers and mechanics are the most physically active staff, taking regular exercise more than three times a week, according to a new study.

Employees in leisure and tourism were ranked second. A survey of 2,000 workers by the British Heart Foundation (BHF) to mark its cycling campaign, found mechanics did some form of physical exercise more than four times a week.

Bankers were also in the top 10, as well as nurses, teachers, plumbers and hairdressers.

The main reasons for taking regular exercise were improving physical fitness, having a healthier lifestyle and losing weight.

Doctors, dentists and bankers were most likely to cycle, with nine out of 10 saying they cycled each week.

The main reasons stopping people cycling to work were distance from offices, or the dangers of cycling, although many cited a lack of showers at their workplace.

Martin Mears, events manager at the BHF, said: 'Cycling is a fantastic way to have fun and improve your heart health and can be done in the evenings and at the weekends.
