I've been doing shoulder presses with barbell since the beginning. Like 3 years now.
Four weeks ago I started my Test E and EQ cycle. Is it wise to change the shoulder main exercise with barbell to dumbell now? Since I've never really trained delts with dumbell, it may take up to month to get the right tehnique. Right now the hands are shivering even with light weight. With barbell everything is OK like usually.
Would that change be good for muscle size? Or would I have better results if I'd stick with barbell?
