As a late 40s man who got into surfing late in life, I recently signed up for the Accelerated Surfing Program, and I'm really impressed so far. I've viewed videos from other sources, but this stuff is next level. ASP is a deeper-level, more "nuts and bolts" type of program that covers things that good surfers are doing but, for whatever reason, is rarely talked about.
Watching their free material on YouTube made alarms go off in my head: "This is something you need to get your surfing to the next level." I actually have a clear direction and am steadily progressing now.
