Shoulder extension or lack of ROM (range of motion) with shoulder extension causes your shoulder blade to “dump” forward.
When ever you run out of range of motion your body looks for ways to compensate and that’s what your shoulder does…
…shoulders round forward and causing potential pain.
Today we will be discussing:
- What shoulder extension is
- Shoulder extension versus shoulder flexion
- How to improve shoulder extension
- Shoulder Extension Mobility Drills
Tired of doing research and just want a proven mobility program that will help improve your range of motion and optimize your positioning? Check out our virtual mobility classes.

What Is Shoulder Extension
Shoulder extension is a movement of the shoulder joint (which is a ball in socket) where the arm moves behind the body (extension).
It’s important to have adequate shoulder extension for a number of reasons:
- shoulders won’t round forward (push ups, dips, muscle ups, bench press, etc)
- If your sport demands you to throw
- strengthening the muscles involved in shoulder extension can improve your overall shoulder stability
Let me show you an example:

Looks like my push up position and my neck is really just about up to my ears doesn’t it?
Yeah…
…no bueno.
You want to depress your shoulder blades “back and down” like the image below.

Only thing I changed was being extremely intentional about keeping my shoulders back and externally rotating my hands into the ground.
Now what happens if you do that and your shoulders still round forward?
Well…
…you have run out of range of motion and that’s probably why your shoulders hurt after doing:
- dips
- push ups
- bench press
- muscle ups
Awareness is step one, step two is a little bit of education, step three I’ll gives you the tools.

Shoulder Extension Versus Shoulder Flexion
Asking yourself what is the reason my shoulder extension is limited?
Check out the full write up I did on the best shoulder mobility exercises where I break everything down in great detail.
But to answer your questions it’s:
- restricted muscles (pecs and bicep tendon mainly)
- poor movement patterns
Let’s help you fix that!
Your shoulders take on a lot.
You want them to be stable, strong and mobile.
I would encourage you to do that little series often to improve your shoulder health.
Consider something like:
- 1-3 sets
- 5-10 second holds in each position
- as often as you can
Shoulder flexion is when you are lifting your arm UP above your head. In the example in the video above…
…it’s where I was laying prone (face down) and holding the I position.

How To Improve Shoulder Extension
If you are a reader of ours you know the first thing we want you to do is…
…TEST.
We love the test and re test model because it lets you know what is working.
Which then allows you to find out which mobility drills are giving you the best return for the time you are spending on them.
When you want to improve your mobility we have a process that we have found to be extremely successful.
FRC, Kinstretch, PAILS & RAILS is what we have come to love for our process
Step 1 To Improving Shoudler Extension | SMR
“Smash” your tissues also known as foam rolling.
Now for most the lack of shoulder extension is going to be because of tight and restricted:
- pecs
- bicep tendon
Here are some video resources on how to “smash” those:
Spending about 1-2 minutes on this area and just exploring any lines of tension.
If you find an area that’s really tender…
…yeah, that’s where you probably need to spend some time.
Stop there, quit moving around, and just work on breathing through your belly and sink into the ball.
Step one we are working on doing some self myofascial release.
Now let me be clear…
…you aren’t actually breaking up any muscle tissue.
However, you are reducing some muscle tone and communicating to your nervous system to get these muscles to relax.
And that’s important because what’s easier to stretch?
- a muscle that’s locked up and restricted?
- or a muscle that has a little blood flow to it now?
Spend a minute or two per side and then let’s get on to step #2.
Step 2 To Improving Shoudler Extension | Passive Stretch
Now that the tissue has relaxed a little bit you we want to focus on diaphragmatic breathing and get as deep into the stretch as possible.
We encourage our clients to take an inhale for 4 seconds and an exhale for 8 seconds.
That can be challenging in the beginning so do what’s best for you and you lung capacity.
Maybe 2 seconds in 4 seconds out and gradually build up.
The objective is during your two minutes is to get deeper into your stretch before you apply PAILS and RAILS.
Here is a write up I did on ring muscle up progressions if you are trying to master that.
Step 3 To Improve Shoulder Extension | PAILS & RAILS
First step we did some tissue work to relax the muscle.
Second step we got into a passive stretch for two minutes and now we want to begin to work ON our mobility.
You see, passive stretching feels great and yes it lengthens your muscles…
…but you aren’t creating strength at that end range of motion.
That’s what PAILS and RAILS does.

I’m going to provide video examples down below but in case you are reader and that’s how you process things let’s talk.
- we did the ring dip stretch passively for two minutes
- then here I am holding this stretch (in the photo above) and ready to begin pails and rails
How to do PAILS AND RAILS for shoulder extension
- Walk out to your end range of motion without your shoulder rounded forward.
- PUSH down on the rings and CONTRACT all the muscles on the anterior side of your body aka the front side. Do this for 10 seconds, this is the PAIL.
- Take a breathe or two and do the complete opposite and contract all of the posterior muscles aka the back side (your delts and triceps) for 10 seconds.
That is one rep.
After 1 rep of pails and rails you should be a little deeper into your stretch. Take a few breathes to get even deeper before ramping up for rep #2.
Just a little plug here…
…you could just join our mobility program and each day I’ll guide you through a daily 20 minute mobility program to improve both your mobility and joint function.

Within our mobility program we help athletes optimize positioning, improve function and get strong.
Shoulder Extension Mobility Drills | Reverse Table | #1
The reverse table pose is a great shoulder extension opener and is extremely demanding on your biceps and shoulder complex.
In the video I show and example how to make it easier if you are having a hard time getting into the position.
Shoulder Extension Mobility Drills | Crab Shift On Box | #2
We have talked about the “test and re-test method” a lot.
What that means is finding which stretch or mobility drills helps to improve your range of motion the fastest.
That’s why we give you several different drills and stretches to try.
So you can find what that works best for you.
The crab shift is now beginning to challenge your shoulder extension even more.
Get those shoulders back, drive your hips up, hold for about 10 seconds and repeat.

Shoulder Extension Mobility Drills | Crab Shift On Rower | #3
A step up from the crab shift on the box we are not on the rower.
And the rower is going to allow your body to glide and really work your end range.
It’s a great stretch however you may feel some discomfort on your elbow. If that’s the case check out some of there other mobility drills we have listed below.
Side note – since you are someone who is wanting to improve your overhead mobility…
…you may be aware of how important it is to have adequate t spine mobility.
Check out my top 5 thoracic spine mobility exercises.
Shoulder Extension Mobility Drills | PAILS & RAILS | #4
This exercise is solid for when you are going to be doing things like bench press, push ups, and dips.
Create strength and get strong at end range.
This an exercise that is pulled form our K2 Mobility program and we like to program like this:
- spend 2 minutes in a passive stretch first
- the perform 5 reps of pails and rails
As discussed in the video 10 seconds pushing into the block and 10 seconds lifting away from the block as hard as possible = 1 rep.
Shoulder Extension Mobility Drills | Bear Roll | #5
This is a nice combination of the reverse table video above.
We like it because it creates a little bit of movement and when you are cold it’s a great way to get some blood flow to your shoulders as you start to open up.
Focus on quality of movement and get about 10 reps.
Shoulder Extension Mobility Drills | #6
This shoulder extension drill is great because the position isn’t very demanding and you can easily throw it into your warm up.
We created a small list of other things you can do to warm up your shoulders here.
It feels good and can meet you where you are at.
Don’t make the mistake of…
…rounding your shoulder forward.
