I can lower the bar to my chest on warm up sets, but as soon as the weight gets heavy, I feel a lot of strain/stretch in my front delt area. The strain feels like its in the joint directly above my armpits.
Same feeling when I lower myself real deep when doing dips. It doesn't feel like my delts are being worked, but more like they're being torn apart, and I have very little power pushing out from that position. I stopped doing dips because of the discomfort.
Just pulling my elbows back, I can see that I can't really pull it far enough for my fists to be in line with my chest.
Should I forget about touching the bar to my chest and stop a bit above to save my shoulders? Or is there something I can do to improve my shoulder mobility?
