There is no room for relaxed yoga or coffee in Klingon fitness — only hardcore, discipline and strength test from the very morning! I just came across https://betterme.world/articles/morning-calisthenics-routine-for-men/ and it's very similar to their training for warriors, where they work purely with their own weight until complete failure. After such a morning complex, an ordinary working day in the office will seem like an easy rest. Coffee will no longer be needed, because the adrenaline will be on the scale by nine in the morning.
