OK - I'm thrilled. Compared to what I did before the 2-year hiatus of movement, this seems so small. But it is great for me. I've walked 4x since D and I returned from vacation. And 2 of those times, this is the BIG thing, have been in the morning before work.
Starting next week, I plan to switch two of my walks to Jari Love's Extremely Ripped - with no weights for the first month. This program uses compound moves to work the full body and is done at a fast enough pace so that the heart rate remains somewhat elevated. Perfect for me.
And now it's time to get ready for work.
