I am active, but most of the things I do don't make for action shots.  The one exception is running; even with that I'm not fast.  But, as they say, slow is faster than those who are on the couch. 

What kind of action do you do during your day?  Walking the dog? Vacuuming?  Pickleball?  Carrying laundry up and down stairs?  Chasing children?  Whatever it is, photograph how you move.

The thing to remember with action shots is that you need a fast shutter speed to stop the action.
