What is exercise?

Physical activity is a broad term that covers any activity that moves your body and speeds up your breathing and heartbeat. This can include exercise, which is structured physical activity that aims to improve health and fitness. It can include both exercise sessions and everyday activities such as housework.

Types of exercise

Exercise can be grouped into three main categories:

Aerobic exercises – use large muscle groups and cause your heart rate to rise. Aerobic exercise increases your capacity to use oxygen, which improves heart and lung fitness. With time, strenuous tasks become easier.

Strength training – involves making your muscles work harder than usual against some sort of resistance. Strength training is also known as resistance training or weight training.

Flexibility exercises – stretch your muscles and help improve your range of motion.

How active should we be?

Australia’s Physical Activity and Sedentary Behaviour Guidelines for Adults outline what types of exercise to do and how often to exercise. They are based on scientific evidence supporting the connection between physical activity, wellbeing, disease prevention and quality of life. The guidelines recommend that you should:

• move more and sit less
• aim to be active on most, preferably all, days of the week
• get a total of 2½ to 5 hours (150 to 300 minutes) of moderate intensity exercise or 1¼ to 2½ hours (75 to 150 minutes) of vigorous intensity physical activity, or an equivalent combination of both moderate and vigorous activities throughout a week
• do 2–3 strength-training (resistance) sessions a week
• break up long periods of sitting as often as you can.
