Being physically active is one of the best things you can do for your body aside from eating healthy.
It is good for your heart, your stress level, your brain, your bones, muscles, your immune system, your
quality of sleep and your mood.

You don't have to spend hours to see the benefits.  Every little bit helps.  20 minutes here.  10 minutes there.
Do things you like to do, dancing, jogging, gardening (lots of leaves to rake right now), brisk walking,
skating, join a intramural sport team, or walking or running club.

Sometimes it is hard to keep motivated.  When you do activities with friends you are more likely to stick with it.

Don't do the same workout routine every day.  Your body gets used to it.  And you won't be apt to get bored
and not want to do it.  Challenge your body and your mind.
