as others have mentioned, electrolytes are very important before/during/after cardio and long periods of exercise. personally, i prefer to drink malt liquor to
restore my electrolytes. haha well, i wish it could. anyway, it gets way to expensive to buy gatorade or sports drink bottles all the time so i just buy the powders you mix with water. for work outs i prefer
cytomax performance drink powder. it comes in a bunch of flavors but it sits a little heavy to use with cardio. instead i use packets of electromix because it provides the electrolytes but it only has a slight lemon lime taste so it's basically just like drinking water with electrolytes in it.
