That doesn’t work, you need to stretch the shoudlers - shoulder dislocates with a wooden staff
lats - chin bar etc , and tyry and pull the arms back ebhind the head
wrists of course and triceps
plus your cuffs as well, stick fist/hand into your waist and pull the elbow forward with your other arm.
also when doing militry presses, stick ythe bar on your chesta nd push the elbows up a bit for a bit of force stretching.
tuck your chin in and pull your shoulder back and down, hold for 10secs at a time, do these several times a day
back off the bicep work
doing all these helped me immensely, no problems now
