Pressing for Chest Growth (Without Wrecking Your Shoulders)
Most lifters press wrong.
They arch hard, pin their shoulders back, flare their ribs, and chase range of motion instead of muscle tension. While it may work for powerlifting, if you’re training for hypertrophy (especially pec growth) it’s sabotaging your gains and potentially setting you up for pain.
Let’s break down how to press properly for chest development, based on real-world application, the biomechanics you won’t hear in most gym advice (not relying on 2 dimensional movement/mechanics like many do).
What Most People Get Wrong
Over-arching the lower back and rib cage
Pinning the scapula back and down like a powerlifter
Chasing range of motion instead of keeping tension on the pec
Puffing the chest out at the cost of scapular movement and ribcage expansion
All of this compresses the posterior rib cage, restricts full expansion during breathing, and actually removes tension from the pecs.
What You Should Do Instead
To train the pecs properly:
‘Volumise’ the rib cage: ‘breathe into the back’ i.e. posterior ribs (posterior expansion) and avoid flaring ribs excessively.
Depress the scapula instead of pinning them back
Allow slight protraction at the top of the press (don’t lock your shoulders down)
Use the smallest arch needed: it’s a consequence, not a goal
Stop just past 90° elbow bend and don’t continue going all the way down because ‘full ROM bruh’ *IF it requires you to sacrifice rib and scapula position.
Feel the pec stretch from the inside-out, not from “range”
Alternate arms (e.g. dumbbell presses) to reduce total compression and enhance rib movement (achieve posterior expansion and compression on opposing sides).
The Coke Bottle Analogy
Props to Jonathan Warren for this analogy, gotta give credit where credit is due.
Imagine your rib cage as a Coke bottle. When it’s full and pressurised, all the muscles attaching to it—pecs, lats, obliques stay taut and active. But compress it (by over-arching and puffing the chest), and the structure collapses. The pecs lose tension. No stretch, no stimulus.
A Better Way to Think About Chest Training
Training the pecs isn’t about moving a bar from A to B. It’s about maintaining internal pressure, allowing dynamic scapula motion, and keeping tension across the entire muscle and not just its point of origin (sternum) and insertion (‘upper arm’)
This is why top bodybuilders often look like they’re doing “partial reps” because they’re prioritising muscle tension, not joint travel.
Key Take Homes
If it feels harder, it’s probably working better
Don’t copy powerlifters if your goal is bodybuilding as the nature of the goal will heavily influence the method of pressing.
Listen to your body; if pressing this way makes your pecs sore and pain-free, then keep doing it!
Who essentially, if you want pecs that are THICCC, striated (and pain-free) then start pressing like a bodybuilder (not a bench presser).
