Note to those who may misunderstand, I can and do go for walks (short ones, not the multi-mile marathons kbird and others do), and walk around normally and unaided, and last night I engaged in some moderate hopping. But they do advise you to keep weight bearing exercise moderate, so I supplement it with exercises that have little or no weight bearing on the feet.

Do as your mother and teachers told you. Sit up straight. You’ll be amamzed after a while how much better you back feels just from doing this.
