Living in New Zealand, and particularly in Auckland where you are surrounded by lovely beaches on two very different coasts, you almost feel compelled to get out there on the reasonably temperate ocean. The Pacific Ocean (east coast) is pretty calm, the Tasman Sea (west coast) is pretty rough and this dictates to a degree what you might do on either coast.
A Stand-Up Paddleboard (SUP) is like a broader, more stable surf board which enables you to stand up and paddle on the ocean. You can buy solid or inflatable boards in a variety of sizes. It certainly gives your core a good bit of exercise. I get a real sense of peace when out there with nothing but the sound of the waves gently lapping on the board and a gentle breeze blowing. It is as close as any of us will get to walking on water!
