If I've ever been in doubt about how sedentary my life is, all I have to do is go to the gym. Comparing my activity level now to what it was 10-20 years ago is bad enough, but when I compare it to my mother's who is 91, it's horrific. I did my time on the elliptical and the treadmill which is by no means impressive but is a start. Then I saw the mother of one of my former students. She is 50 and rode her bicycle 20 miles yesterday and said she usually does 20-30. She was going what I thought was fast on the elliptical (forward and backward pedaling), but she said this was a light day since yesterday was heavy with the bike riding. Light for her was 6 or 7 mph. I do well to go 2.5 mph on it and definitely can't last as long as she did!
There were some other women around my age who walked about the same pace I did on the treadmill. I realize it's not a competition and am glad it isn't. It just drives home to me how inactive I've been physically, and it shows! I feel like crap most of the time unless I exercise and then feel better, dammit!! I used to ride my bike (never more than a few miles, though), took aerobics classes, played tennis, swam, walked a lot, and danced (that requires dating which brings up some other activities I used to participate in, too). Sorry, Neil Young, but I've been rusting instead of wearing out.
OK, so it's a start. I'm walking on the treadmill and pedaling on the elliptical. Next the weight machines and a class called Silver Sneakers for us seniors. After that, I'll see. The dating activities look doubtful. At least I can still hold my own in a trivia game.
