After three years, a few elbow and arm injuries, and training with different stretching techniques, I feel like I finally made a bit of progress on the shoulder extension.
A few days ago I was bendier and got maybe 1 cm higher, unfortunately I didn't record that.
But I feel that I hit another plateau and it's not easy to get unstuck. If it were hamstrings or hips, I could try to stretch harder, but shoulders and elbows are somewhat more delicate, at least mine.
Any suggestion besides biting the bullet and waiting to see if progress eventually resumes ?
