My name is Wallie and i'm new over here. I'm skateboarding since i was 5 years old and now longboarding for six years. Last year i suffered a knee injury but next year im planning on going on my first surf trip. I have two questions:
- is being an experienced longboarder (on the streets) a benefit when it comes to starting with surfing? And if so, how can i practice already to do some excersises that could help me before picking up a surfboard next year?
- how stressful/painful is (wave)surfing for your knees?
Thanks in advance for helping me out, it means alot

Wallie
