Stand up paddle boards (SUP) offer a fun, relaxing way to play on the water. With a minimum of gear, you can paddle ocean surf or placid lakes and rivers. Paddle boarding delivers a full-body workout and thus has become a popular cross-training activity. And since you stand at your full height, you can enjoy unique views of everything from sea creatures to what’s on the horizon. To get started, you just need some basic SUP gear and techniques.
