If you can’t paddle out to the lineup, you can’t surf. So now’s the time to build your upper body strength, lest you get stuck boogie-boarding on the whitewash with the toddlers. First head to an indoor pool. To isolate your upper body, put a pull buoy between your legs, slide Speedo’s training band over your ankles, and prepare to slog through endless freestyle laps. You can also try putting your surfboard in the pool’s lap lane, but in my experience, that doesn’t go over so well.
