Of course water is the obvious answer I am looking for something more than water. I am doing a week long kayak ocean fishing trip in Panama in August and am looking to stay on as good shape as I can considering I will not only be baking in the sun for hours on end but will be using a lot of energy between pedaling the kayaks and cranking in fish and lures. I figured this group has to be the most physically active group so I figured I would ask the question here
