I have never ever understood the love of orange juice people have. Juice in general (sweet fruit juice without any fiber) seems as bad as a candy bar. Now, a different juice of whole fruit blended into a drinkable glass of sunshine (without having to go outside and get UV damage) is another story.
A classic combination of pineapple and oranges is what I have in mind today. Prep them both (use that ceramic knife I know you've bought by now) and put it in your blender. It certainly fueled today's workout session nicely.
