plateau

That soul-crushing moment in your fitness journey when your progress flat-lines harder than a bad EKG, and no amount of burpees seems to move the needle. It's the training equivalent of purgatory, where your body stubbornly refuses to get stronger, faster, or leaner despite your continued suffering. Breaking through requires switching up your routine, because apparently your muscles got bored with the same old torture.
