Stand-up paddle boarding is a great way to combine fun with exercise. The experience can be relaxing and serene or adventurous and challenging. Health benefits include improving balance, core strength, arm strength, and durability. People of all ages can participate and either take a slow, relaxing paddle on a large body of water or challenge themselves by riding whitewater on a river. Another activity is paddle board yoga, testing the balance and strength of even the most experienced yoga masters.
