Nate Florence and Koa Rothman are among the very small group of people who can surf for a living. Not even surfing on tour — just surfing. Contests don’t matter, although they’ll still surf them on occasion, but winning events isn’t their bread and butter. Their bread and butter is just plain old surfing, and they do it very well. But in order to surf very well, as you likely know, there ain’t nothing like surfing a lot. For the Average Joe, however, that sometimes isn’t an option — work, kids, life, etcetera all get in the way — so Nate and Koa talked about the best things you can do to make sure you’re able to maximize your time in the water. Quick hint: it’s cardio. The video above is just one small part of an hour long podcast that you can listen to here.
