Had a friend who's a former pro athlete at my CF gym yesterday so I decided to try my first backwards roll since he was there to spot me.
There were a couple of loud cracks heard as I rolled past inverted and my friend said it was because I didn't open my arms during the movement.
I tried to do it like he said afterwards but it felt a little painful. I just rewatched Eva's backwards roll to support video and so her starting with her arms locked in a 90deg position and closely tucked to her body.
My question is how should I go about practicing them on my own bearing also in mind the fact that I had a slight rear-deltoid injury this summer that still tingles when under a lot of stress...
