Stand down Corporal Fonda. At ease Sergeant Motivator. The Territorial Army is determined to succeed where legions of celebrity exercise videos have failed by bringing about fitness regime change in Britain. The health drive, timed to coincide with freshly minted new year's resolutions, will see the TA sharing its physical expertise with the nation and encouraging us to exercise whenever - and wherever - we can.

Although 70% of people in a recent survey said that getting fit was their number one priority last year, nearly half the respondents said that work or family commitments had stopped them fitting in their workouts. But the poll also revealed that 80% of people thought trained army instructors were the best fitness teachers, superior even to soap stars and TV presenters. The TA hopes its 14-week Fitness That Works programme, designed to encourage workers to exercise during their lunch hours, breaks and journeys to and from work, will get people doing chair dips in the office and running on the spot on train platforms.

"I believe that the public has a better understanding these days of the all-round benefit of improved fitness, but they don't have the time to squeeze gym visits and workouts in to their busy schedules," said Lieutenant Colonel Phil Watkins, of the Army Physical Training Corps. "Soldiers claim that one of the key benefits of joining the TA is that they see a dramatic increase in their fitness levels."

The TA's routine includes a two-week "conditioning programme" to gently introduce the body to fitness before more intense sessions are brought in.

Army instructors say there is no excuse for not squeezing in a few laps of the boardroom. "We are convinced that anyone can get fit if they have the right know-how, and who better to learn from than the TA who are the experts at combining fitness with busy schedules," said Col Watkins.
