Theresa Strange "plogs" six days a week. On most mornings, she picks up enough garbage to fill two 30-gallon trash bags.
"While I was walking I noticed a lot of trash, and I said, 'you know, I can multi-task,'" she said. "Why not pick up the trash and get the exercise at the same time?"
Strange encourages others to join "plogging" fitness craze.
