As an adult, my ability to easily W-sit is responsible for some serious IT-band issues that cause a ton of knee pain and even contribute to chronic back pain. It's been a major factor in preventing me from being the kind of runner I want to be--and while that might sound unimportant, I be worried about taking away this excellent form of exercise from my kids. I've also dropped a ton of money on physical therapy to strengthen the muscles around my hips and knees, which have a ton of extra looseness because of sitting this way as a child. If my kid started sitting this way, I'd do as much as I could to prevent it.
Interesting. I'm the PP with the 44 yr old brother who still sits like this. My brother is a serious runner, usually places in the top 3 for his age group and he lives on the west coast where a lot of people do marathons, and the only person I know who does not have knee, leg, form issues with the # of miles he trains. He also does Crossfit/swims/bikes but mostly runs. I never realized sitting in a W caused problems.
