I have
1) Do I need to depress my shoulder more at the top of the movement?
2) Should I "shrug" at the bottom of the movement to allow for greater scapular retraction?
3) Do I need greater posterior tilt?
4) Do I have the correct body alignment?
5) Would it be more helpful to post a "front" point of view next time?
6) Are there any other problems that I did not mention?
Thanks,
Have a good day ^^
