The analogy is tempting. But gym training isn't what work is. At work the goal is not learning - it's delivering value.

Doing weights is not the same as say, updating the gym with shiny new weights; or migrating all the weights in the gym to metric. At the gym, if the current weights need to go and new ones installed, a forklift will one-shot it.

Seeing the difference empowers you to choose the right approach for the right situation.
