Someone whose job is to help people decide what type of exercise is best for them and show them how to do it. 1 receptionist at a gym 2 gym manager 3 teacher trainer 4 personal trainer

I changed my mind. Go with 4.

Explanation:

1 The job of the receptionist is to answer phones and take down data as well as give hours operation. They are not qualified to answer questions on exercise.

2. The office manager does what the name implies. Not 2

3. 3 and 4 are both correct. I would pick 3 but 4  is equally likely. 3 gives general instruction

4 gives specific instruction.
