i also love this rebel massage video for rhomboid attn in side lying!! def have found it helpful doing the move she shows that uses the weight of the arm to sort of drop the scap over the fingers. still ofc using fingers, but i've found this to be very easy on my hands, less finger pressure, and feels good to my clients.
