We can see the video now, thanks for sorting that out 🙂It's actually not looking too bad, you're catching the wave and angling down the line, however your main issue to start with is having the confidence to walk up earlier in the glide section and that's just something that comes with practice (believe me, I know!)Look at the walk-up drills in the Beginners Course and remember to get your back foot angled at 45 degrees from the nose so your rear knee points more towards the way you're going, instead of sticking out to the side. That will help you get your hips and shoulders more front-on and enable you to stack on the front foot so you can stand up smoothly.You've got a good start there, so keep at it 👍
