Aerobic activities are activities that keep teenagers' bodies moving enough to increase their heart rate and make them breathe harder.
To gain health benefits, Australian guidelines recommend teenagers should engage in at least 60 minutes of aerobic activity, daily.
There are two intensities of aerobic activity:
Moderate-Intensity: Heart rate will beat faster than normal and breathing will be harder than normal. Moderate physical activity includes activities that get teens gently huffing and puffing. They're about as intense as a quick walk.
Vigorous-Intensity: Heart will beat much faster than normal and breathing will be much harder than normal. Vigorous physical activity includes activities that get teens huffing and puffing a lot, and sweating, eg. running games or riding a bike fast.
The one hour of daily aerobic activity does not have to be done all at once, or even in big blocks. It can be enjoyed in small blocks of time throughout the day.
