I am reasonably fit but I don't seem to be very flexible in my shoulders. For example when I lift anything above my head (nothing heavy) I seem to really struggle and get pain the my shoulder muscles at the back.
When I do yoga and we lie flat on our backs with our arms above our heads I seem to be the only one who cannot put my arms flat on the floor.
Does anyone know any exercises that may help this? I've started yoga in the last few week to try to improve.
