I've been working on these for over a year now. I can't tell how good they are. I feel like my ROM is decent, however, I feel a pretty marked/substantial stretch when I do these on the front shoulder (anterior deltoid). This is with 5 lbs, moving them in any closer leads to popping or grinding; and I very well know that's a no-no in GB and Coach's book. So, let me know if there are any specific things I can do to progress out of this damned element. Thanks.
