The exercise where you lie in wait for time itself to suffer.

means A long, flat, rigid piece of timber (or the isometric exercise of holding your body straight and rigid like one, propped on forearms and toes).

from From Old North French 'planke' / Old French 'planche,' tracing back to Late Latin 'planca,' meaning a slab or board — itself related to Latin 'plancus,' said to describe someone flat-footed. The flat board sense came first by centuries; the torturous exercise borrowed the shape, not the wood, somewhere in the fitness-craze era.
