Regardless of whether you're paddling for recreation or fitness, SUP surfing or racing, good form should be an imperative to everyone who steps on a SUP. Proper paddle form will help prevent injury, make you go faster using less energy, and make standup paddling way more fun. If you're going to do it, do it right!
Jimmy Terrell, founder of Quickblade Paddles and former Olympic canoe champion, is one of the world's top authorities on paddle form. Recently Jimmy shot a sequel to his popular SUP instructional video, The Very Important Paddle Stroke for SUP. I've posted them both here and I highly recommend reviewing the first and watching the second to get your form in check.
