If it came in the same text with "trainer", I would go for "موجّه" or "مدرّب جماعي".

Coach:
Someone whose job is to teach people to improve at a sport, skill, or school subject.
Someone whose job is to train and organize a sports team.

"The main difference between coach and trainer is that coach instructs, directs and trains a sports team or individual sportspeople to develop their skills whereas trainer helps people to reach their personal health and fitness targets."

Coach: Someone who asks intelligent questions to encourage the coachee to come up with their own solutions wherever possible. Gently enabling them to stretch their boundaries and improve in the agreed area of work.
