Physical activity does not have to be vigorous or done for long
periods in order to improve your health. Walking is low impact,
requires minimal equipment, can be done at any time of day and can be
performed at your own pace. It's a great way to improve or maintain
your overall health.
For general fitness, most adults should aim for
10,000 steps per day. This figure
may rise or fall depending on a person’s age, current fitness level,
and health goals.
