Check whether "trainer" is acting as noun, slang in your sentence. A definition is only useful when the grammar matches the way the word is being used.
2. Test the nearest option

Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.

Final meaning check
Before publishing a sentence with "trainer", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.
When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.
