Reduced physical and mental toughness in today's force, how as leaders are you combating this?

As I progress in my career and have the opportunity to lead as well as mentor more soldiers and NCO's, I find myself observing a trend that I believe many other leaders are seeing also. This trend is the reduction of physical and mental toughness that I believe has slowly deteriorated over the last decade. For instance, receiving young soldiers fresh from OSUT that cannot pass the APFT, and also having soldiers becoming increasingly more reliant on other people to accomplish basic tasks. This seems to be increasing as time goes by, and I would like to see how other leaders combat this and what efforts do you take to turn this behavior around?
