Yes, getting started is hard.
You are overweight and discouraged. Dieting is hard enough. And now you are menopausal on top of everything else. It's more important than ever to get an exercise program together that you can live with.
You don't have to run a marathon, or swim the English Channel, or ride a bike from Maine to Florida. Even though you already know what to do, I'll spell it out for you:
What you do have to do is move your body every day.
You can start with easy steps - literally - by simply walking more in your everyday life. Take one extra flight of stairs, get off the bus two blocks before your stop, park your car at the far end of the lot, walk around the block after lunch, walk to someone's office instead of calling.
Once you start doing these things, you'll find that it seems ridiculous to wait for the elevator for a few flights of stairs, to wait for the local bus when you can walk, to fight for a close parking spot at the store, to eat a meal without moving afterward, or to waste time on the phone when you can get your questions answered quickly with the added benefit of personal interaction.
Every little bit helps in getting you started to the more fit, more healthy you.
As a certain athletic apparel company notes: Just Do It.
