I was training delts with Leroy Davis about two weeks ago and he showed me how to do them how he and Dorian used to do them back in the day. The Blood and Guts video only has Dorian doing them seated but more often than not they did them standing.
Keep feet shoulder width apart.
Have dumbells at front of body palms facing each other.
Lean slightly forward into the weight
Bring dumbells up keeping arms only slightly bent (in fact, he had me doing them almost straight armed)
By the time you get to the top of the movement, the dumbells should be slightly higher than the delts themselves (almost level with the traps)
The pinky should be higher than the thumb.
Hold for a second at the top (this takes practice, believe me)
Lower slowly.
We did three sets, starting with 40lbs, then 45s, then 50s to finish off. As soon as we finished with the 50s, we dropped down to 25lb dumbells and just crank out the reps but just keeping the arms at the sides at the bottom of the rep.
I had to drop my usual dumbell weights just to do them this way but doing them this way fucking works - my delts were still sore three days later. That was in addition to doing smith machine presses and upright rows, finishing off with some rear delt work. Damn good workout that was.
