I've been hearing for several years about competitive cyclists whose non-load-bearing exercise can reduce bone density. So I took a test, and sure enough, I have a slight Osteopenia. Has anyone else looked into this?

It helps to do load-bearing exercise too, but... well... I really don't like weight lifting or going to a gym. Running used to be fun, but with these old knees it's not a good idea any more. Hiking downhill is also good (oops, knees again!) but still doable. Do I need some cheese with this whine?

Most of us as we age having thinning bone density.  Slight osteopenia isn't much to worry about thankfully!  Osteoporosis though can be worrying depending on how bad it is, and typically affects far more women than men.  Lani Simpson has an excellent book on this subject.  And there are other books that will take you through the wonderful world of osteoclasts and osteoblasts.  

Weight bearing exercise of course (and gentle impact exercise), calcium rich foods and possibly supplements can help (plant-based calcium is said to be better absorbed).  But ALSO magnesium and vitamin d to help absorb and other micronutrients come into play.   Medication is an option if it's very serious. 

If your bone density is really a problem, fall prevention is a priority.  

Good luck to everyone dealing this this issue!  I say read and learn as much as you can.  

Dan's comment reminds me that Becky, who loves to walk, often wears a weighted vest when she goes out. The vest, worn under a coat or whatever, has little pockets all over in which weights are placed. 

Wow, I never heard of cyclists losing bone density (osteopenia). One more thing to worry about as we, ahem, get older. That said, I heartily endorse weight training as a way to halt or at least slow down bone density loss. Not only that but weight training builds strength and endurance. Certain exercises with weights translate well to cycling, like squats and lunges. I understand the reluctance of going to a gym. Not all gyms are alike. I found a gym that I really like that I've been going to for 15 years. It's not full of Arnolds or lithe spandex clad beautiful women (I wish). There are just regular people there that many are close to my age and women, too, about my age.  It's social in a similar way to our club. Feel free to reach out to me if you're interested and I can tell you which gym go to (hint: It's in James Village). The combination of weight training and cycling is my fountain of youth. Well, I ski a little, too.

Be happy to help anyone out that needs weight bearing exercises - I have chainsaws, powered trimmers, and good heavy tools to lift while you feel the satisfaction of working on my property.
