Stand behind two men with roughly the same size chest and you can usually tell within a second which
one trains. It isn't the chest that gives it away. It's whether the shoulder looks round from behind
or flat.
That roundness comes from one small muscle sitting on the back corner of the shoulder β the rear
deltoid. And almost nothing most men do touches it. Push-ups don't. Dips don't. Planks don't. Every
pressing movement sends your arm forward, and this muscle only works when your arm travels backward,
which is a direction that essentially never comes up in a normal day or a normal home workout.
Both of these are done lying face down on the floor and need nothing at all.
1. T-RAISES β 15 reps. Lie face down with your legs together and your forehead resting on the floor.
Stretch both arms straight out to the sides so your body forms a T, with your palms facing down
toward the floor. Lift both arms as high as you can, squeezing the back of your shoulders, hold for a
second, then lower slowly without letting your hands rest on the ground.
One honest note on that: palms down is the harder version on the shoulder joint. If it pinches at the
top, turn your thumbs up toward the ceiling instead. Same exercise, friendlier angle, and there's
nothing wrong with using it.
2. Y-RAISES β 12 reps. Same position, but take your arms out wide and angled forward past your head,
so your body makes a Y rather than a T, with your thumbs pointing up. Lift both arms just a few
inches off the floor, hold for two seconds, then lower under control.
Two things decide this one. Keep the lift SMALL β a few inches is correct, and if you're getting a
big dramatic lift then your lower back has taken over the job from your shoulder blades. And start
the movement by pulling your shoulder blades down and back, away from your ears, rather than by
throwing your hands upward. If you feel it in your upper traps or your lower back rather than the
back of your shoulders, lower the height until you don't.
Between the two you're covering both the shape of the shoulder and the muscle that stops it drifting
forward again.
