What does "work out" mean? All the meanings.

"I work out three times a week." (go to the gym, train). This is the meaning most learners meet first. You can "work out at the gym", "work out at home", or "work out with a personal trainer". The activity itself is often called a "workout", written as one word when used as a noun: "That was a tough workout." Notice the difference: the verb is two words ("I work out"), but the noun is one word ("a good workout").

"Can you work out the total?" / "I'm trying to work out why it failed." Here "work out" means to find an answer through thinking, reasoning, or arithmetic. You can "work out a problem", "work out the cost", or "work out a solution". It can also mean to gradually understand something: "It took me a while to work out how the machine worked." In this sense it is very close to "figure out", which Americans use slightly more often in casual speech.

"It didn't work out between us." / "I hope it works out for you." When plans, relationships, or situations "work out", they reach a good result. "Everything worked out in the end" is a common comforting phrase.

When something "works out", it resolves itself successfully, or in context, it simply resolves itself (not necessarily well). "It didn't work out" means it failed or ended. For example, "The new job didn't work out, so I left after two months." You might also hear "work out well" or "work out badly" to make the outcome explicit: "The trip worked out really well."

The context makes it clear. "She works out every morning" = exercise. "Work out how much we owe" = calculate. "I hope it works out" = I hope it goes well. A quick test: if there is a number or a question involved, it usually means calculate. If there is a body, a gym, or fitness, it means exercise. If there is a plan, a relationship, or a hope, it means succeed.

Students sometimes say "I worked out the problem" when they mean they exercised, which confuses listeners. Remember that the exercise meaning does not take an object like this. You "work out" (no object), but you "work out a problem" (with an object). Also avoid saying "I did a work out". The correct forms are "I worked out" (verb) or "I did a workout" (noun).

Think of the word "out" as things coming out into the open. Your energy comes out at the gym, the answer comes out when you calculate, and a good result comes out when a plan succeeds. All three meanings share this idea of something being produced or resolved.

Casual to professional. All three meanings are common. In a workplace email you might write, "Let's work out the details on Monday." In casual conversation a friend might say, "Don't worry, it'll all work out." The calculate meaning is especially frequent in British English, where "work out the cost" sounds very natural. Americans often prefer "figure out" for the same idea, though both are understood everywhere.

"Work something out" can also mean to reach an agreement, especially in negotiations or disputes. "The two companies worked out a deal" means they agreed on terms. "We need to work things out" between two people can mean either to solve a disagreement or to save a relationship, so listen carefully to the context. This overlaps neatly with the "succeed" meaning, since both point toward a positive resolution.
