not sure, but I think you're bent over and you just raise your arms...I call them bent over arm raises...this is just a guess though, great for rear delts and back..
With shoulders its important to know that your shoulders lift the arms (as in upright row) then push the arms (as in shoulder press), and they raise the arms (as in latural raise)
Always work your shoulders and traps together, and work 1 of each movement
could try dumbell press, close grip upright row, and latural cable raise.
or for the mass building guys clean and double press, then some dumbell raises.
