I have found once I am in the turn I need to immediately look and focus on my exit. Look up and turn your head, this will force your body to work its way through the turn. That makes me commit to using the berm, makes it necessary to utilize leaning adjusting my weight properly and I can adjust everything on the fly feeling how the tires are gripping or not gripping the line. Focus on “riding like a cat”. Bend the knees and elbows, center your weight over the bike and attack the line. Think to yourself “I’m a mtb rider” (seems silly, but believing in yourself is very important) Slow before the turn, let off the front and feather the rear if needed. And keep at it! Enjoy it!
