3. Types of Physical Activity
Vigorous Activity
Also called cardiovascular activities. This means that these types of exercises make your heart beat faster.
When you body sweats from doing these types of activities, it acts as an “air conditioner” to bring your body’s temperature down.

4. Try This!!!
Place you hand over your heart. Can you feel it beating? It should be beating pretty normal.
Now I want everyone to do 10 jumping jacks.
Now feel your heart again. Is it
beating faster now?
Your heart is helping to pump blood and oxygen throughout your body.

These activities do not make our hearts beat faster, but they help us to stretch our bodies and become more flexible.
