Lying on one side, or in a side plank, and holding a DB in the other hand, pressing it laterally/vertically so that you end up looking like an L, with the weight in the air.
It would be abduction of the joint, so yes, it would work them, but why do that?
Well I want to make them bigger, but I hate isolation, so I figured why not do a compound movement that targets them.
On top of overhead pressing, that is.
i think he means pressing rather than raising. if so id doubt itll be more effective than normal pressing, as the anterior deltoid is still needed to shift the weight.
id actually avoid it as it leads to an unnatural twisting of the shoulder.
It seems to pretty much be a shoulder press though, just at a less effective angle (thereby recruiting the delt for less time)... I dunno, you can try it and see how it goes, but I think it would end up feeling awkward and not be all that beneficial.
What lifts do you do right now?
Squats, cleans, bench, rows, dips, overhead press, pull ups...the good stuff.
I dunno... my favorite direct lifts besides pressing are high pulls, hang cleans, and lat raises. I just think what you are describing would be a less effective DB OH press because it's a lesser ROM.
I have heard alot of people do basically a side press with a dumbbell, but lying on a bench instead of in a side plank position. supposed to work well
