Hi,
I'm trying to progress through the manna progression and the stiff leg windmills is causing me grief. When I do the exercise my shoulder sounds like it's grinding and feels horrible. I know my arm's not perfectly vertical the whole time but if I slip even slightly it pops or grinds. The left is worse than the right. I don't have a video available yet (I'm hoping to be able to film it tomorrow) but in the mean time is there anything I can do to make it easier or a different exercise to get more mobility through the shoulders?
Thanks,
Steph
