Do you mean like elbow > cradle transfers (and similar)?
Yes bring it from your left cradle to the right inner elbow. Then
hold it for about 20 seconds roll it to your cradle or palm. Then
back to the other arm. Now if you reverse this and can not stop it at
the inner elbow try raising your arm. I had this issue for a LONG
time and still do. One thing that helped a lot was to raise my arm so
my arm was flat and not bent at the elbow.
A roll to the elbow is a precise throw and catch. You start at the
palm and end at the elbow stall. So another exercise is to throw it
from one to the other. At this point you don't have a good catch at
the elbow.
Another exercise that may help is to roll it slowly and try to stall
it in several places on the arm before the elbow.
Have fun, enjoy and smile as that helps break your frustrations. Take
breaks and try not to practice mistakes.
I have a great roll from the palm to the elbow and onto the ground ;)
