Hello,
I am having some problems with my shoulders with practically the same movement.
I am having problems with negative hanging leg raises and windshield wipers.
my shoulder fails before my core does.
i have had a couple of rotator cuff problems. But they have healed and I believe the muscles are well balanced, but I might be wrong.
it is my front delt that is in pain.
what is wrong with me shoulder, is it flexibility? or strength?
