You may find that undo stress (not the good kind) will be felt on the bicep (stretch out),their inserts, wrist and the elbow joints..For some, also the shoulder joints. If planning to have an experience with them, a lighter weight may be advised.
Probably best to begin with the DB's overhead, opposite fingers of each hand,facing each other, lowering the DB's to around 45 degrees to the sides. There is a good reason why not too many BB'ers include this exercise in a delt workout. Good Luck.
