Bad form on shoulder day is a fairly common occurrence. If you're lucky,
you'll find yourself the object of a gym-fail video on YouTube. If
you're unlucky, you'll find yourself with a rotator-cuff injury.
We all make mistakes, but we can and
should learn from them, I've
identified nine of the most common blunders I see people commit on
shoulder day, and provided ways for you to correct them.
1
Never assume all overhead presses are equal
The overhead press may be your go-to multijoint movement for shoulders,
but that doesn't mean all its variations work your deltoid musculature
the same. Not even close! That's why you should understand how each
variation works a bit differently so you can pick the right tool for the
job.
For example, lowering a barbell in front of or behind your head actually
changes the emphasis on your deltoids, as does your elbow position
relative to your torso. When you press overhead with dumbbells, your
upper arms go straight out to your sides; that's your cue that your
middle delt is positioned to undergo maximal contraction.
When you do Arnold presses or barbell presses in which the bar is in
front
of your head, notice how your elbows pull forward—they're no longer
directly out to your sides. That slight shift recruits the front delts
and relieves some of the tension from the middle delts. While that
doesn't discount the effectiveness of these kinds of presses as great
shoulder movements, they're not the best at emphasizing the middle
delts.

Dumbbell and barbell presses in which you take the bar behind your head
will better target the middle delt region. Machine overhead presses
differ by manufacturer, but if you keep an eye on the direction of your
upper arm, you can easily pick out whether you're getting much
contribution from the front delt.
If you want more tension on your front delts when doing overhead
presses, by all means choose the front barbell version, or consider
Arnold presses.
2
Never overarch your back doing overhead presses
All kinds of things can go wrong with too much weight on the bar,
especially when you press that weight over your head. In the
all-too-common scenario where you bend backwards to press more weight,
your body searches for a way to gain better leverage. This can quickly
turn an overhead press into a steep incline press, which recruits the
chest musculature to a greater degree puts your lower back at risk.
Note that this overexaggeration of the spine comes with a steep price,
and I'm not just talking about the reduced stimulus for your delts. To
press safely, you want your spine in a neutral or slightly arched
position with your core muscles—both on the front (abs) and back (low
back)—braced and contracted. But that's not what's going on here. The
hyperextended position of the thoracic and lumbar vertebrae combined
with heavy weight can contribute to a herniated disc.
When doing seated overhead shoulder presses, keep your back pressed
fully against the bench. When doing them standing, be aware of
overaggressive arching. You'll certainly want a degree of arch in your
back, but don't turn the exercise into a dangerous standing incline.

Never go super heavy with behind-neck barbell presses
While some lifters slip into a 3-sets-of-10 mentality for the bulk of
their training career, many others cycle heavy and lighter training
periods. While doing low-rep training with heavy weights can help build
stronger delts, it might be a mistake when you're loading extra plates
on the bar and repping it behind your head.
When doing a behind-the-neck barbell presses, the shoulder muscles are
in their weakest anatomical position at the bottom of the move. Using
too much weight on this movement can increase the risk of a tear,
according to Guillermo Escalante, DSc, CSCS.
Escalante recommends going in front of the head if you're going to use
very heavy weight, although doing the behind-neck overhead presses with
moderate weight is a safe way to target the meat of your delts.

Never use a close grip on upright rows
To work your middle delts maximally, you want your upper arms moving
directly out to your sides. That happens by taking a moderate grip on a
bar when doing upright rows, not an extremely close grip.
If you take a close grip on the bar, watch where your elbows go. They
move forward and out to your sides, not directly out. Using a close grip
causes internal shoulder rotation, which isn't always healthy for your
joints. This not only put less emphasis on the middle delts, but also
increases the likelihood that you could have long-term shoulder damage.
Push your grip wider on the bar to allow your elbows to kick directly
out to your sides, which is perfect for building up your middle delts.

Never limit your range of motion
Many trainers terminate single-joint movements like lateral raises and
front raises when they hit roughly shoulder height, but the middle and
anterior delts haven't reached the ends of their range of motion. In
fact, you can take these movements even higher, as the muscles are still
contracting. Some experts suggest you can go as far as 45 degrees past
the horizontal plane.
The longer range of motion makes these movements harder, so you may
sacrifice a bit of weight, but the extra range and time under tension
makes these moves worth adding to your workout every so often in
conjunction with heavier single-joint exercises taken to about shoulder
height.
