HI! Brett says-
Try to get a good knee grip at the end of the slide so the right hand and right knee take all the weight, that way you can take your left hand off. It’s a lot of Grip needed in the right hand. Looks like you are sliding your knee too far down and lifting your chest at the end of the slide instead finishing upside down with the chest. My knee doesn’t slide as close to my hands as your knee is and I think that’s why.
