I really hate lateral raises. In order to do it safely, you have to have your pinkies out and on top, and with this safer style I find I'm at least 35% weaker, meaning I'm putting less weight against the muscle. I like upright rows best for the medial deltoid.
But obviously the OP needs to do rotator work if he's looking to strengthen the joint rather than the muscle.
Be careful, mate.
I don't like barbell upright row. This is as internally rotated as the humerus will get, and you're elevating the humerus right into the impingement zone on every rep.
The dumbbell version is a slightly safer alternative, although I feel that there are still much safer ways to challenge the upper traps and deltoids.
You may be someone who has seen fantastic results with upright rows, but personally, I don’t write them into any of my programs. If I want to overload the delts, I can do so via more effective means ( overhead pressing with dumbells, rows, pull-ups and lateral raises).
If I want to overload the upper traps, I’ll stick with deadlifts and shrugs; all allow for greater loading and a more systemic effect.
To summarize, if you've ever had a shoulder problem, suspect that you might have one now, or have other predisposing characteristics (i.e. poor posture, lots of overhead work in your daily life) that might increase your risk of impingement, you'd be wise to omit upright rows altogether.
Oh, one more thing, "
medial deltoids" don't even exist.
The term "medial" is a directional term that means "toward the midline" of, in this case, the body.
From the anatomical position - standing, arms at sides, palms supinated (facing forward), the head of the deltoid that is sandwiched between the anterior and posterior deltoid fibers is actually the farthest away from the midline of the body of all of the heads of the deltoid.
If anything, it should be called the
lateral head! As such, these fibers are referred to as the "
middle deltoid," a term that correctly identifies their position between the anterior and posterior deltoid.
