Stand-up paddling has been exploding in popularity around Hawaii, thanks to its high fun and low difficulty quotients. If you’d like to give it a try, the best place to get schooled is at Paddle Core Fitness, at Ala Moana Beach. Not only will you learn the basics of balancing and paddling, but instructor and owner Reid Inouye has developed his classes into a focused exercise routine that’s roughly 10 times more fun than working out at the gym. “It’s basically like walking on water,” Inouye says. “You’re looking down, you can see all the ocean life. But at the same time it’s a good workout that hits your upper body, core, sides, legs, cardio.” You can ramp up the difficulty once your skills improve, too; PCF offers beginner, intermediate and advanced classes. 723-5357, www.paddlecorefitness.com.
