Hello,
I have seen several videos or posts talking about elbow external rotation when we do straight arm exercise or some kinds of excercises that involves keeping the elbow stragiht.
Do we actually need this?
If so, what is this good for?
For example,
- planche lean
- dips at the top(or throughout the movement)
- push up at the top(or throughout the movement)
- handstand
- L sit
When we do these, do we have to externally rotate the elbows? Or is it kinda optional?
Thank you.
