I've been working the Foundation Series, Stretch Series and Handstand One for almost three years. I've had massive gains in all areas and am very pleased with all of my progress. However, I am really struggling with the Straddle Planche. I seem to be stuck and confused with how to progress. I feel like I have a decent planche lean but struggle with sPL/SE1. I can do an advanced frog stand but struggle with a tucked planche and an open planche is way out there. I've tried countless things to try and progress but I must really be missing something key.
My question is the following. Are there any exercises I can video to highlight potential issues in my technique or strength. I'm willing to shoot anything or try anything to get past this hump.
