Jumping

I just wish my knees were strong enough to walk. I had a misconception that if I didn’t use my knees for much that I could avoid knee replacements like all of my friends were getting. Well, my knees are great. But they don’t have any strength in them. Since I first fell four years ago and ended up in a rehabilitation nursing home, my spinal pain has been so bad that lying down on my side is the only thing that alleviates it. I need to walk my dog but so afraid of walking and tripping, I just stay home and do nothing. Horribly depressed. Loneliness is a definite problem and makes me want to do absolutely nothing because every time I go somewhere, everyone is younger and no one wants to strike up a conversation. This is not like me. I used to go places by myself and no one was a stranger. Most of my friends have passed and the ones left live out of state or they are busy with their grandchildren and children. My family is scattered all over with only one younger sister who lives here and is busy with her friends. I only see her at Christmas and maybe lunch twice a year. She does take me to procedures that require anesthesia. It’s just she’s 13 years younger and has her own friends plus she has a demanding job. There are no senior centers here.
I am in too much pain to volunteer.
Jump? I rarely walk and when I do it’s with a cane.

Great job to everyone exercising with the goal of increased BMD and better health in mind!!! At 63, I also exercise vigorously. I was able to see a decent improvement from exercise alone (and nutrition, supplements, lifestyle changes) , meaning no drugs, so I know it works. However it was too slow (11% increase in BMD of total spine in 19 months) and unchanged at the femoral neck, so my Dr had me start Tymlos. I've had great gains on Tymlos, much faster. However, my femoral neck was still changing too slow, in spite of 3 days a week of weightlifting (45 mins of machines and free weights), 3-4 days a week of intermediate level pickleball (and treadmill, stretching, etc).
I'm blessed to have no serious problems with my body structure other than lingering upper hamstring pain. In an effort to get the femoral neck going, I kinda made up what I call leg slams since I didn't like jumping. Like Dr Doug says, impact improves bone. However, doing these in addition to my routine finally go the femoral neck going! In 6 months (I do a Dexa every 6 months) femoral neck BMD went up 6.46%, on one side, 3.44% on the other. I've now added two signs I keep around the house that say "STOMP" to remind me to stomp around even while at home!
So keep searching for what works for you and your body and your situation/lifestyle.
This is a marathon, not a sprint. And we're in it, like it or not, for the duration! I have faith in you! Carry on Bone Warriors!
