Stand up paddle boarding (SUP) offers a fun way to play on the water, with the added benefit of a full-body workout. And, since you stand at full height on your board, it gives you a unique vantage point for viewing what's down under the water and out on the horizon. You can also get the benefit of being on the water without buying an expensive boat, a.k.a Break Out Another Thousand. Unless you have what it takes to own a boat, this alternative will get you on the water without the headache of owning a boat.
