Paddleboarding requires boulder-shoulders, "for holding the paddle up and drawing it out of the water," says Kalama. So, although you might scare a few beachgoers, the Frankenstein is an essential.
Walk with your arms straight out in front of you, at shoulder height. "Don't let them go below shoulder height, and you'll look like Frankenstein walking down the beach," says Kalama. "After about two minutes, you could care less about what anybody is thinking. If you get up into the three, four minutes, or more, you're getting strong."
