Variability is the key

Instead of specializing someone who is specialized in something else, we need to un-specialize them. We need to give people what they don’t have at the foundational level first. …

Once that foundation is established we’re able to move into almost any specialized activity, and that’s the goal. Not just to be good at exercising for a while, but to have bodies that are capable of doing whatever we want without injury in the real world, for the rest of our lives.
