Ez curl bar
Rev curls-overhead tri ext-high pulls
All ten reps, no rest between, strict form with no swaying or lower body movement, 3 sets.
I use this as my Hypertrophy work after strength training.
Or just dumbell raises from side to front to bent over to punish Delts.
I don't like doing anything holding a weight straight out in front of me for the duration of the exercise, due to the fact that gravity is pulling straight down on the weight and it put more of a strain on my shoulders.
