I did them yesterday, standing, free with a barbell.
Today im SORE in my delts, not that my delts are lacking but DAMN im going to do them every single workout, as i felt it activated all three heads.
Superior movement, i banged my head at the wall after this... for not doing this all these years...
Of course done right to avoid injury. lower the bar to the ear level and stop couple inches before locking out. Controlled reps, medium weights. no need to go heavy
