Whether its purchased by the bottle or from the tap, water, is the cheapest and healthiest drink option. Eight, 8 ounce glasses per day will keep you full, hydrated and your skin will be better and brighter. Water hydrates but it also cleanses the system and keeps things moving.
Electrolyte-loaded athletic drinks can be a source of unnecessary calories so drinking plain water is fine until you're exercising for more than one hour a day. At that point, feel free to go for regular Gatorade-type drinks, which can give you a beneficial replenishment boost.
