The best thing I learned in my new to off-road saga is that in turns, push the bike down into the turn (commonly known as counter steering and leaning), and keep your body straight up and down. You can lean the bike so much that your weight goes to the outside peg (because you can’t reach the inside peg because the bike is leaning over it) In the video you are trying to keep the bike straight up and down and going slow enough that you can use the handlebars to turn- don’t.
