What can I do to decrease may chances of getting lower back pain?

In this study they found, that for the average overweight American a modest increase in activity time by 17.6 minutes a day (123 minutes a week) reduces risk of lower back pain by 32 per cent and for morbidly obese people an increase of 2.1 minutes can make substantial difference. An example would be adding more time in moderate activity (walking) into your day.
