was diagnosed with idiopathic, i.e. cause unknown, osteoporosis last year after batteries of tests to rule out a more sinister cause. Calcium supplements prescribed ended up gaving me iron defficiency anemia! All better now.
Activity wise weightbearing exercise is what it is all about; but the injury which led to the fracture which led to the diagnosis was to my knee so I have to go softly softly. Thusly I've joined a jogging club and am currently on a 'learning to run' course with lessons 3 times a week building up to 5km after 10 weeks. My personal goal is to be able to run for 80 minutes/10km.
I've probably got the best CV fitness of all the learners, thanks to all the cycling, but am overweight, possibly I'm proud to be one of the fat-fit, and I can't say cycling to work the morning after a run the night before thrills me to bits. But learning to run with a large group, we've forty odd learners, in a club setting is a whole lot more fun than pavement pounding on your todd.
