It is recommended that you aim to do a minimum of 150 minutes of moderate intensity physical activity each week. This could be brisk walking, swimming, gardening, dancing, playing sport or many other activities.
The 150 minutes doesn't have to be all in one go, you can spread it across the week in short bursts to suit your lifestyle and fitness level. For example, you could do a 30 minute walk, five days a week.
You are encouraged to walk at your own pace, but at a speed that makes your heart beat a little faster and your breathing a little quicker.
