this is why fat fucks are the way they are; they're quitters who wilt the moment they encounter the slightest adversity in their plan  Exactly. Outside of formal training I think that's generally how people improve any kind of physical skill. You encounter something that's just on the edge of your capabilities. And you push yourself to achieve it knowing that eventually what's hard will become your new normal. These kinds of situations aren't obstacles, they're opportunities for growth!  And sure, we're just talking about playground equipment in this specific example. But it goes back to what you're saying. That unwillingness to admit failure and then work to overcome it is one of the biggest reasons why so many fat people end up that way. Hell, I think it can be said about our overly sedentary culture in general.
