The advantages of seeing a specialist vs a primary care physician is that the specialist knows exactly about that field of medicine. One circumstance for a specialist: Your eye is bleeding and red, you might want to go see an ophthalmologist because they focus on the eyes. One circumstance for a primary care physician: You feel weak, dizzy and you are vomiting, you have no specific area of pain, so you might want to see a primary care physician because they know about different fields of medicine instead of just focusing on one.
Regularly scheduled exercise can do all of those depending on what /how you do it and who you are.
