prefetch_related display ManyToManyField values

Using Django
3

I am after a list. and the query set does work perfectly well. I have all the data I can see from the django debugging toolkit, but I don’t know how to show it in my view. I think I just came up with an idea like this:

    exercises = list()
    for exf in formulas:
        exercises.append(exf.exercises.all())

looks silly, but I can see my exercise names
the problem is I cannot access the third table Exercises’ fields from here like:
exf.exercises.name or exf.exercises.image
