BUT recently I decided to try something new... and I am walking up the hills backwards! I am amazed that I can do it! It uses an entirely new set of muscles. Whew!
Also, a coworker recently started walking with me who is much smaller and half my age. But she told me the other day that she went back to work and people were really surprised when she told them that to walk with me she really has to bust butt and work hard to keep up with me!!
That was so nice to hear since when I was younger and thinner I was SO competitive and it really "fried" me to have to be so slow when I started and have everyone passing me, etc. I am really enjoying my improved fitness.

! Keep it up
