Knees getting tired
Hey. I'm new to snowboarding so I've been working on going down the hill on my backedge (front facing down the hill) and going left and right to control my speed. I find that this makes my knees really tired so much that after a few hours, I could only go down the hill backwards since my knees can't take it anymore.
Are my knees getting tired normal? Should I gain more strength throughout the season?
I'm worried that I'm using incorrect form and hurting myself in the process.
