Answer:
The correct answer would be D, Observations, duration of exercise and body measurements.
Explanation:
Journal is the best place to record information about your workout. Information about workouts include observations, duration of exercise and the body measurements. Thus it include anything related to workouts. There is no need to enter record for what you took in your meal, or what you did not take, or what your friends are doing, or what are your feelings and frustrations. Any information related to workouts will be recorded. So option D would be the most appropriate.
