Hey all. I'm currently at beginner level due to my location, but my brother was an avid surfer and grew up with the dogtown boys. I unfortunately didn't have the luxury as he did to grow up on the coast. anyway, in memory of him and of my own desire I want to surf. question is... are there any particular exercises besides pop ups that I can be doing to strengthen and condition my muscles? I'll be in Portland in early August and don't want to spend the entire day down or beached. also, found a place that offers a class but does anyone recommend any others or someone to do private lessons? I've done the research and watched some vids but I want to be prepared. hoping to make the most of it so I can honor my brother properly. thanks in advance!
