I'm working on natural movement in various directions, it's a skill challenge area for me. It's also a physical issue since I'm not skinny, am old, and my knees are complaining when I move sideways. I *think* it's more tendon/ligament because walking forward is fine. The first possible solution is turning the leg at the hip to put the knee in proper alignment, but maybe there are better ways? I keep thinking the Ba-gua folks must have this down to a science...
