Risks of immobile shoulders
Shoulder mobility requires scapula stability (your shoulder blade) and flexibility of the eight muscles that support the joint. An unstable scapula can lead to shoulder impingement, causing inflammation, pain and discomfort that can last for months.
While stability is important, too much stability can put extra stress on your shoulder joint and increase injury risk.
How to test shoulder mobility
The easiest way to test your shoulder mobility is with the reach test:
- Raise one arm up above your head while leaving the other by your side
- Bend each of your elbows and attempt to get your hands to meet in the middle of your back – the goal is for your fingertips to touch
- Repeat on the other side
- If your hands can’t touch and there’s a significant gap (more than 2 inches) on one or both sides, it’s time to improve your shoulder mobility
How to improve shoulder mobility
If you find that your fingers don’t meet, you can improve mobility by adding shoulder stretches into your routine. After re-establishing better mobility, you can add shoulder-specific strength exercises.
Even if you already have good mobility, it’s worth adding shoulder stretches into your conditioning work to reduce the risk of shoulder injury.
Mobilize Your Thoracic Spine
Your shoulder’s ability to move overhead is tied to the mobility of your thoracic spine. You cannot lift your shoulders and arms all the way up without arching your back to some degree.
If your upper back is stiff and in a hunched posture, your shoulders will struggle to achieve a full range of motion, often leading to compensations such as arching your lower back or impinging the shoulder. Improving thoracic mobility, especially thoracic extension (gentle backward bending of the upper spine), is an underrated way to give your shoulders more freedom instantly.
If you loosen your upper back, your arms can reach overhead without your shoulder joints jamming or your neck and lower back overworking to compensate. To achieve this, incorporate some thoracic spine stretches or exercises into your routine.
Upper back exercises for shoulder mobility:
- Cat-cow mobilization
- Thoracic extension over a foam roller
- Thread-the-needle twist
As your posture improves and your spine extends more easily, you’ll find overhead exercises are easier and smoother to perform. These moves are especially important if you spend a lot of time sitting, driving or at a computer. These moves help counteract hunched postures, and can significantly improve shoulder mobility.
Also… do shoulder pass-throughs
Shoulder pass-throughs are a great – and often overlooked – mobility drill. This is a dynamic move where you hold a stick, towel, or resistance band with a wide grip in front of you and then slowly lift it over your head and move the object behind you, keeping your arms straight.
This exercise stretches the chest, shoulders, and rotator cuff through a large range of motion and can dramatically improve how your shoulders feel during overhead activities. Coaches love it as a warm-up for weightlifting (many Olympic lifters do PVC pipe pass-throughs regularly).
How to do it
- Grab a stick or resistance band. Use a very wide grip—wider than your shoulder width.
- Start with the stick or band in front of your thighs. Hold it firmly.
- Slowly raise it overhead. Keep your arms straight and bring it up and over your head.
- Bring it back behind you. Move the stick or band behind your body as far as is comfortable without straining.
- Pause if you feel a tight spot. Don’t push through pain. Stop, breathe, and then bring the stick back to the starting position.
- Perform 10–15 slow repetitions. Move slowly and with control, focusing on smooth motion.
Finally – hang from a bar to decompress and stretch the shoulders
Simply hanging from a pull-up bar, in a passive hang, is an effective way to improve shoulder mobility. When you hang with arms extended overhead, it gently opens up the shoulder joints, stretches the latissmus muscles and allows the shoulder blades to rotate upward fully.
All of which increases your overhead range of motion and even help with shoulder impingement issues by creating more space in the joint. It also helps pull your shoulders into proper alignment by stretching tight chest muscles and strengthening the passive stabilizers.
How to do it?
- Grab the bar with an active grip (squeeze it, don’t just passively hang)
- Let your body hang naturally. Allow your body weight to stretch your arms and shoulders. Keep your grip active and avoid shrugging; let your shoulders elevate naturally without forcing them down.
- Start with short hangs. Aim for 10–20 seconds per hang when beginning.
- Gradually increase your hang time. As your grip strength improves, work up to 30–60 seconds per hang.
- Do multiple sets throughout the day. Try incorporating a few sets (2–3) spread out across your day for best results.
- Modify if full bodyweight is too intense. Keep one foot lightly on the ground, or use an assisted band to offload some of your weight.
Bonus: it also improves grip strength and can decompress your spine. If full bodyweight is too intense, keep one foot on the ground or use an assisted band to take some weight off. Make hanging a habit, and enjoy shoulders that move easier and feel better.
These tips aren’t meant to replace your regular gym routine, but – done regularly – will enhance it. These strategies create stronger, more resilient shoulders that can handle more, recover faster, and move better.
