Surfing Waves

Heyy, unfortunately I can´t go surfing as much as I would like, however, I´d like to improve my surfing skills. Do you know any youtube channel or exercises to help me get in shape and keep improving.
Thankyouu in advanced

Things that would help are arm shoulder/strength strength and endurance exercises such as swimming, balance exercises, cardio workouts and probably watching surfing videos and trying to learn where they take off how they turn etc. People often make the mistake that surfing is just a skill to learn but there is knowledge that needs to be learned as well. Knowledge about the ocean and waves that mostly can only be learned in the ocean but I think maybe watching videos of which there are many that go over how to surf may help get you used to the ocean somewhat. Whatever skills you can learn on land will be useless unless you understand the ocean. You can google surf lessons and there are endless videos. Some of the surfers here think skateboarding is a good tool to learn surfing on land. I remain unconvinced but still it might be better than not surfing for some.
