Why we programme this

With no cap to hide behind, an AMRAP measures your engine directly: how much repeatable, quality work you can put out in the window. It builds the sustained-output capacity that lets a hybrid athlete keep the throttle open while others fade in the back half. The first round should feel almost restrained — the score is won in the last few minutes, not the first.
