Walking 'not enough to get fit'

"A team from Canada's University of Alberta compared a 10,000-step exercise programme with a more traditional fitness regime of moderate intensity.

Researchers found improvements in fitness levels were significantly higher in the second group.

They told an American College of Sports Medicine meeting that gentle exercise was not enough to get fit.

Lead researcher Dr Vicki Harber said: 'Generally, low-intensity activity such as walking alone is not likely to give anybody marked health benefits compared to programmes that occasionally elevate the intensity.'

Dr Harber and her colleagues were concerned there was too much focus on simply getting people to take exercise, rather than on its intensity."
