I tried it and found it to be quite challenging. In fact, I could barely lift a leg during it. My posterior chain is definitely a weak spot and I'm excited to strengthen it.
I plan to practice it over the next mesocycle so I can see if it helps me achieve greater lift in my L-sit.
You can see my video explaining and demonstrating the exercise here:
