Go Outside!  
It doesn’t have to be perfect weather.  Even going outside in inclement
weather has the ability to invigorate you.

Take a walk.  Ride a bike.
Finding local hiking or bicycling trails is often easier than you think.
Bring a friend, bring your kids, or just bring your dog.   Feeling pensive?
Just bring yourself.

group.  With the added social aspect, you’ll forget your exercising.
