SHOULDER PACKING

Form cues

Think of packing the shoulder blades down and back into the "back pockets" — this is the target position.
Maintain the packed position throughout; this exercise is about learning and reinforcing a motor pattern, not loading.
Keep the chest up and out; do not let the ribcage collapse forward as the shoulders pack.
Breathe normally throughout — this is a low-intensity neuromuscular re-education drill.

About

Shoulder packing is a corrective exercise that teaches conscious control of scapular depression and retraction, building the neuromuscular foundation for safe overhead pressing, pulling, and carrying.

Instructions

Step-by-step technique

01

Set Up Tall

Stand or sit upright with your chest lifted and arms relaxed at your sides. Let the shoulders rest in a neutral position — not pinned back, not slumped forward.

chest up and out
02

Depress the Shoulder Blades

Draw both shoulder blades straight down, away from your ears, as if sliding them into your back pockets. This downward movement comes first — before any squeezing together.

down before back
03

Retract Gently

From the depressed position, draw the shoulder blades slightly together. Aim for a firm, stable position — not a maximal squeeze that creates tension.

firm, not strained
04

Hold the Packed Position

Hold for about five seconds while breathing normally. Keep the chest up and do not let the ribcage collapse forward as the shoulders pack.

05

Release and Repeat

Slowly release back to neutral and repeat for 8–10 controlled holds. This is a motor-pattern drill — quality of position matters far more than effort.

Common mistakes

What goes wrong — and why

Mistake

Shrugging instead of packing

Elevating the shoulders rather than depressing and retracting them is the opposite of the intended movement.

Think "down and back," not "back and squeeze"; the scapulae should move down before they move together.

Mistake

Ribcage collapsing forward

Allowing the chest to cave in during the pack reduces the scapular movement and encourages thoracic kyphosis.

Keep the chest actively lifted and out before initiating the shoulder pack.

Mistake

Over-squeezing at the end

Forcing maximal retraction can cause tension and is not the goal; a comfortable packed position is ideal.

Aim for a firm but not strained position — enough to stabilise, not so much it causes discomfort.

Variations · Progressions · Regressions

Adaptations for every level

Regression

Seated Shoulder Pack

Sitting reduces the postural demand and makes it easier to isolate the scapular movement.

Progression

Shoulder Pack under Load (Overhead Carry)

Maintain the packed shoulder position while carrying a light weight overhead to apply the motor pattern under load.
