Why we need to exercise
Exercise benefits the physical and mental health of people of all ages.
As well as boosting our mood, regular physical activity reduces the risk of developing many serious illnesses including:
- heart disease
- lung disease
- Alzheimer’s disease
Exercise also makes it easier to maintain a healthy body weight and can help us to manage existing conditions including arthritis and cancer. According to the Australian Institute of Health and Welfare, 55% of Australian adults are not meeting the physical activity guidelines and 67% of Australian adults were either overweight or obese in 2017-2018. In the same year, almost 25% of Australian children aged between five and 17 were also overweight or obese.
Children and young people
The Australian Physical Activity and Sedentary Guidelines recommend the following:
- birth to one year – regular moving on the floor from birth
- one to five years – at least three hours of physical activity each day
- five to 12 years – at least one hour of moderate to vigorous physical activity each day and several hours of light physical activity
- 13 years to 17 years – at least one hour of moderate vigorous physical activity each day and several hours of light physical activity
Vigorous activities are those that strengthen muscle and bone and children aged five to 17 should do these at least three days each week.
Healthdirect Australia outlines the many benefits of exercise for children including:
- developing healthy bones, muscles and joints
- improving balance and posture
- improving strength and muscle control
- maintaining a healthy weight
- developing social and teamwork skills
The Australian Physical Activity and Sedentary Guidelines recommend adults aged 18-64 years are:
- active on most, preferably all days each week
- do between 150 to 300 minutes of moderate intensity physical activity or 75 to 150 minutes of vigorous intensity physical activity each week
- do muscle strengthening activities on at least two days each week.
Regular physical activity can help adults manage:
- body weight
- blood cholesterol
- blood sugar
- blood pressure
The Australian Physical Activity and Sedentary Guidelines recommend adults aged 65 years and older:
- do some physical activity no matter their age, weight, health problems or abilities
- should be active each day in as many ways as possible
- should accumulate at least 30 minutes of moderate intensity physical activity on most, preferably all days
If you’re new to exercise or haven’t been that active recently, it’s important to gradually build up your exercise over time.

Tips for getting active
If you’re just starting out with a new exercise program, it’s important that you start out slowly and gradually build up your exercise levels over time.
You should also choose an activity that you enjoy and will look forward to.
It’s also a good idea to set measurable short-term and long-term goals. For example, setting goals of walking an extra 20 minutes each day, rather than just becoming more active.
