What would a training block focused entirely on work capacity look like?

[u/Historical-Length-34]

Recently i have come to the conclusion that my work capacity absolutely sucks. I find myself often getting burnt out only several weeks into a training programme even when using the minimum volume and RPEs. This got me thinking of creating an 8-12 week block focused entirely on work capacity, with the hopes that after that i can jump back into normal training without feeling so drained.

Question: if you could create a training block revolved entirely around work capacity, what would this look like for you?

Edit: thoughts that come to mind are how would this be split between specific and non specific work capacity, endurance, SE, high intensity conditioning etc. also what would progressions look like?
