Don't know if a mentioned that (the preface "Dear Diary" is implied and assumed but it could as easily be "Dear Daughter"!) when I walk in the evening, I like to stop at East Park and do pullups on the bar over the entrance to what used to be the tennis court. Since I've been reading Next of Kin by Roger Fouts, about the American Sign Language (ASL) communicating chimpanzee Washoe and her family of humans and other chimps, I've been wondering why I can't be as strong as a chimpanzee. Toward partially achieving this, I'm trying to learn to hang one-armed from the bar or the nearby children's jungle gym as I think that would strengthen my arms. Not very successful yet as I can only put weight on one arm if both feet are on the ground but maybe if I keep trying I'll build up enough strength to do it.
This evening I tried to apply what I read on the Internet about Chi Walking which is to lean slightly forward and let gravity help with the forward motion. Also, you're not supposed to land on your heels and push off on your toes but rather you land in a mid-foot strike. I'd need to take a workshop to really learn how to do it but the concepts I've read so far on the Chi Running (includes Chi Walking) website are very interesting.
