Which phrase means to exceed expectations in effort or outcome?

Going the extra mile signifies putting in additional effort beyond what is required or expected, leading to an exceptional outcome. This phrase emphasizes a commitment to going above and beyond in one's duties or endeavors, often leading to impressive results that surpass what was initially anticipated. In many professional contexts, this expression is used to highlight dedication, work ethic, and a willingness to invest extra time or resources to achieve a better outcome for a project, task, or customer satisfaction.

The other phrases do not convey the same meaning. "Green around the gills" refers to someone who looks ill or nauseous; "a far cry from" indicates a significant difference or distance from something; and "strenuous" describes something that requires substantial physical effort, but does not inherently suggest exceeding expectations. Thus, the phrase that best captures the idea of exceeding expectations in terms of effort or outcome is indeed going the extra mile.
