I've been stuck on Windshield Wipers and negative leg lifts for a long while. The exercise feels like it requires a lot of core exertion.
When I started, I couldn't just "hang" and found bending my arms and pulling myself up the stall bars to be helpful. I'm now able to hang with straight arms for this and negative leg lifts.
I also find it difficult to keep my legs completely straight sometimes.
Half windshield Wipers are too easy. Seems like a bug jump.
Here's my video. I know I'm going to too fast here, I was tired as it was my 5th set.

Any feedback is helpful! Thank you!
