Workout vs. Work Out – Which is Correct?

The distinction between workout and work out lies in their grammatical function: workout is a noun referring to a session of physical exercise, while work out is a phrasal verb meaning to exercise, to solve a problem, or to develop successfully. Both are correct in American English, but they are used in different contexts and parts of speech.

Workout or Work Out – Which is Correct?

Both “workout” and “work out” are correct in the English language, but they serve different purposes. The key difference is their part of speech and, consequently, their meaning. Workout (one word) functions as a noun, while work out (two words) functions as a phrasal verb.

The one-word noun “workout” refers to a session of physical exercise. For instance, you might say, “I had a great workout this morning.” It names the activity itself.

The two-word phrasal verb “work out” means to engage in physical exercise, to solve a problem, or to succeed or develop in a particular way. Examples include, “I need to work out more often,” “Can you work out this math problem?” or “I hope things work out for them.”

The Best Trick to Remember the Difference

To remember the difference, think of the “noun-verb” trick:

• If you can replace the term with another noun (like “session” or “exercise”), use workout (one word).
• If you can replace the term with another verb (like “exercise,” “solve,” or “succeed”), use work out (two words).

Consider this: You do a workout (noun), and you work out (verb) at the gym. The space between “work” and “out” in the verb form signifies the action itself, while the single word “workout” consolidates the concept into a single entity.

Word	Part of Speech	Meaning	Example
Workout	Noun	A session of physical exercise or training.	My morning workout was intense.
Work out	Phrasal Verb	To exercise; to solve; to succeed or develop.	I need to work out more. / We need to work out the details.

How to Use Workout

The term “workout” is exclusively used as a noun. It refers to a period of physical exertion or a training session designed to improve fitness. It can be a singular countable noun (“a workout”) or plural (“workouts”). It is commonly used in both casual and formal contexts when discussing fitness, sports, and health routines.

Just as understanding the nuances of ‘workout’ and ‘work out’ is important, distinguishing between Use vs. Usage is key for precise communication.

Example 1: She plans to fit in a quick workout before heading to work.

Example 2: The coach designed a challenging workout program for the team.

Example 3: After a strenuous workout, I always feel energized.

What are the different forms of Workout?

As a noun, “workout” primarily has a singular and plural form:

• Singular: workout (e.g., “a daily workout”)
• Plural: workouts (e.g., “multiple workouts per week”)

Etymology of the word Workout

The noun “workout” emerged in the late 19th and early 20th centuries, derived from the phrasal verb “work out.” It likely gained popularity as the concept of structured physical exercise became more formalized and distinct from general labor. The process of combining “work” and “out” into a single word reflects its evolution into a specific, identifiable activity.

How to Use Work Out

“Work out” is a versatile phrasal verb with several meanings. The most common relate to physical exercise, solving problems, or achieving a positive outcome. As a phrasal verb, it consists of a verb (“work”) and a particle (“out”), and the two words should always remain separate.

Meaning 1: To exercise physically. This is the direct verbal counterpart to the noun “workout.”

Example 1: I try to work out at the gym three times a week.

Meaning 2: To solve a problem or calculate something. This implies finding a solution or understanding something through effort.

Example 2: The engineers are trying to work out a solution to the design flaw.

Meaning 3: To develop or progress in a satisfactory way; to succeed. This is often used when discussing plans or situations.

Example 3: Don’t worry, I’m sure everything will work out in the end.

What are the different forms of Work Out?

As a phrasal verb, “work out” conjugates like the verb “work.” Its forms include:

• Base form: work out (e.g., “I work out daily.”)
• Third-person singular present: works out (e.g., “He works out regularly.”)
• Past simple: worked out (e.g., “They worked out the problem.”)
• Past participle: worked out (e.g., “The plan has worked out well.”)
• Present participle/Gerund: working out (e.g., “She is working out.”)

Etymology of the word Work Out

The phrasal verb “work out” has a longer history than its noun counterpart, with roots stretching back to the 17th century. Its various meanings evolved over time. The sense of “to solve or calculate” appeared in the 18th century, while the meaning “to exercise” became prominent in the 19th century, reflecting societal changes and the increased focus on physical fitness. The particle “out” often implies completion, extraction, or resolution, which is evident in the verb’s diverse applications.

Related Concepts

Understanding broader grammatical concepts like parts of speech and phrasal verbs is crucial for correctly distinguishing between “workout” and “work out.”

• Nouns: A noun is a word that names a person, place, thing, or idea. “Workout” is a noun, naming the activity or session of physical exercise. Recognizing a word as a noun helps determine its role in a sentence, often as the subject or object.
• Phrasal Verbs: A phrasal verb is a verb combined with an adverb or a preposition, or sometimes both, to give a new meaning. “Work out” is a phrasal verb where “work” (the verb) combines with “out” (the particle) to create meanings like “to exercise,” “to solve,” or “to succeed.” These combinations often have meanings that cannot be easily deduced from the individual words.

Examples from Media and Literature

• “I’m going to hit the gym for a quick workout before my meeting.” (Common usage, referring to an exercise session)
• “The detective spent hours trying to work out the intricate details of the crime.” (Referring to solving a problem)
