Boosting health and morale is easiest when you join a walking group, reveals an investigation published Monday in the British Journal of Sports Medicine.

Walkers enjoyed "statistically significant improvements" in well-being compared to their formerly sedentary state, the probe found.
Small but measurable gains were seen in general fitness, blood pressure, resting heart rate, lung power, cholesterol levels, body fat and in a standard test to measure depression.
The picture was less clear for waist circumference and blood glucose.
Of those who joined a walking group, three-quarters tended to stick to it -- and apart from the odd stumble over roots or wet ground, it is a risk-free activity.
These are benefits that doctors should point out to sedentary patients, the paper said.
