I use cordless phones for exercise.  No, I don't do arm curls. :-) Whenever someone calls, usually my younger daughter who lives in another state and is big on multi-tasking, I walk around the house the entire time the conversation lasts.  She often calls on her way to or from work or out on errands (yes, she has a hands-free set-up in her car; otherwise I wouldn't talk to her).  I can log a lot of hours per month simply doing this exercise.  I also sometimes multi-task, stooping to pick up things that are out of place, running the dust mop over my laminate floors, sorting laundry, etc. I love to walk outdoors, but there are a lot of days (I live in NW North Dakota) when that isn't possible, such as this morning when the wind chill is below zero at nearly noon.  At this time of the year, I also have been known to mall walk to find out where the bargains are with the holidays looming.  I have a free Y membership thru Humana, but at the price of gas and with the Y on the other end of town, I was pleased to read that simple "home work" can count toward my exercise time. I battle the cholesterol bad guys thanks mainly to a heredity problem, etc., and I am determined to come out the winner.
