On the rear delt cable flys on pull day, I see a lot of people advocating to perform bringing your arms more diagonally at around a 45 degree angle as it lines up better with the fibers of the rear delt as opposed to 90 degrees shown in the workout. Personally when I have tried the 45 degree angle in the past I felt it much better in my rear delts. What are your thoughts on the this ? Thank you for all the help and great content 🙏🏼
