Expert writing Tips

Best practice

When referring to physical exercise, use the phrasal verb "work out" without the preposition "on". For example, say "I work out at the gym" instead of "I work out on the gym."

Common error

Avoid adding "on" after "work out" when describing exercise activities or locations. The correct usage is simply "work out" followed by the location or activity. Saying "working out on" often sounds unnatural.

Ludwig's WRAP-UP

In summary, while the phrase "working out on" appears frequently across various sources, Ludwig AI suggests it is often grammatically incorrect in standard written English. A more precise way to express the same idea is to use either "working out" (for exercise) or "working on" (for development). It's recommended to avoid using "on" after "work out" when specifying a location. While present in many contexts, the phrase is best avoided in formal writing. It's better to use alternatives such as "exercising at" or "training at" for more grammatically sound construction. The phrase is most common in news and media, but that doesn't make it a preferred expression in formal contexts.
