Which term describes the duration required to achieve long-term fitness goals?

The duration required to achieve long-term fitness goals is best described as "over a year." Long-term fitness goals often involve significant changes to one’s physical condition, such as improving cardiovascular health, building muscle mass, or achieving a significant weight loss. Achieving these goals typically demands consistent effort and dedication over an extended period, which is generally understood to be a year or more.

In contrast, terms like "short-term," "a day," or "a couple of months" do not align with the expectations associated with long-term fitness objectives. Short-term goals usually refer to achievements that can be realized quickly, often within weeks or a few months, but long-term progress requires a sustained commitment that goes beyond these shorter time frames.
