I'm working on a problem in bouldering where the swinging of my feet take the grip away from my fingers and throw me off.
Specifically, I am in a bat-hang, and need to reach an edge hold about 3.5 ft. away from my hand's current hold. I cannot reach this edge without my feet slipping off. But of course, when my feet do slip, even when I manage to grab the next edge, the swing of my legs inevitably throws me off from the other side.
I can include a photo to show what I'm doing, but I mean to ask a general question:
What are some things I can do to minimize that swing?
I saw several others doing the same problem, release one foot from the bat-hang and bring their knee to their chest, as if to compact. I see that this reduces mass at the outer radius of my body being accelerated by gravity.
Is there anything else I can do? I tried slowly slipping my last foot off the bat-hang, but that's only reducing the foot's fall by a few inches (while destroying the top of my shoes).
Here are some photos of the specific problem I'm working on. But I've had the same question in other problems, anywhere where the feet come off while reaching for a hold.
Here's the starting position of a bat-hang, then how my legs swing after release and finally how I swing off the edge holds due to the swing:
