I posted today about my 'unexplained' gains in upper body strength - then, while walking to the ferry this evening, I had an epiphiny. I walk .6 miles from the ferry to work (and back) everyday. I carry a bag with me that I pack with books, magazines notepads and my lunch. Because I was having some shoulder issues, I quit carrying the bag with a strap over my shoulder, but instead carry it by the handle with my hand. Right hand to work in the morning, left hand to the ferry at night. Tonight when I got home I weighed the bag (a bit lighter because my lunches were gone) and it, together with my purse, weigh 12 lbs!
I think I'm going to go flex in the mirror now!
