For having such a simple appearance, the press-up posture/ability in surfing packs a punch of function…and it’s harder to do that you think! This isn’t just a static plank like you do on your yoga mat (though that is a great tool for training the core strength you need to hold your press-up), but a dynamic skill where you’re constantly making adjustments in your weight center above your board in order to maintain balance (like punching through waves) and direction (when taking-off on waves).
