I got my bone density score... My bones are less dense than they were 3 years ago when I had my last test. -1.5, for anyone who knows what that means.
I checked my calcium supplement... it's a lot less than I thought it was. So I'm going to take more of it and look for a better one. Same with the the Vitamin D. I cover up when I go outside (long pants, long sleeves, hat), so I don't get much vitamin D from the sun. But I don't have much sun damage to my skin, either.
So, more walking! More calcium, more vitamin D. I work out on the elliptical, but even though that's a weight bearing exercise, it's very low impact. I like that, as it's easy on the knees.
But it's the impact that helps build stronger bones. So I'm going to skip on our walks. Not skip the walk, skip on the walk. 50 steps times 3 walks. I don't jog, I don't run, but I can skip.
I used to do something called "the Sally hop" down the hall at work. (I didn't name it that; a coworker did, and it stuck.) It's sort of a sideways skip. I bet that's a good bone building exercise too.
