Hello!
When I do a handstand, there is always an angle in my elbow (I've attached a picture of my handstand and integrated some lines to visualize what I mean). My forearm is parallel to my back, but my upper arm is inclined.
I don't see that same angle in top handbalancers like Yuval Ayalon for example.
So I'm curious what exactly causes this, is it a matter of insufficient shoulder flexion, different elbow rotation, too much protraction of the scapula or some other reason?
