Shoulder Mobility Exercises: 8 Drills for Stiff Shoulders

The best shoulder mobility exercises do not just stretch your shoulders. They get your upper back moving too, because a stiff mid-back is one of the main reasons shoulders feel tight, click or pinch when you reach overhead. If you sit at a laptop all day, your upper back rounds forward and your shoulder blades lose their normal movement, so your shoulder joint ends up doing extra work.

Below are 8 drills I use with clients at my studio in Archway: what each one does, how to do it, and two short routines, one for before pressing in the gym and one for desk workers to do during the day.

Why shoulders get stiff (and why the upper back matters)

Your shoulder is not just one joint. To lift your arm fully overhead, your shoulder blade needs to rotate upwards and your upper back (thoracic spine) needs to extend a little. If your thoracic spine is stuck in a rounded position from hours of sitting, your shoulder runs out of room sooner. That is when you feel tightness at the front of the shoulder or a pinch at the top.

So a good shoulder mobility routine covers three things:

• Thoracic rotation and extension to free up the upper back.
• Shoulder blade control so it moves well on your ribcage.
• Rotator cuff and range work so the joint is strong at the end of its range, not just flexible.

8 shoulder mobility exercises for stiff shoulders and upper back

1. Thread the needle

Start on all fours. Slide one arm under your body along the floor, letting your shoulder and head drop towards the mat, then reverse and reach that arm up towards the ceiling. 6-8 slow reps per side. It is one of the simplest ways to get rotation into a stiff upper back. Full set-up in my thread the needle guide.

2. Open book thoracic rotation

Lie on your side, knees bent to 90 degrees and stacked, arms straight out in front. Open your top arm across your body and let your chest rotate towards the ceiling, following your hand with your eyes. Keep your knees together. 8 reps per side with a 2-second pause at the end. My thoracic rotation benefits article covers more variations.

3. Cat-cow

On all fours, round your whole spine towards the ceiling, then let your chest drop and look slightly forwards. Focus on moving the upper back, not just the lower back. 10 slow reps. A good warm-up for the spine as a whole.

4. Foam roller thoracic extension

Lie with a foam roller across your upper back, hands supporting your head. Keep your hips on the floor and gently extend back over the roller, then return. Move the roller a few centimetres and repeat. 5 reps at 3-4 spots. Avoid the lower back.

5. Wall slides

Stand with your back against a wall, forearms on the wall in a "W" shape. Slide your arms up into a "Y", keeping your lower back and forearms in contact as much as you can, then pull back down. 10 reps. This trains your shoulder blades to rotate upwards properly.

6. Band pull-aparts

Hold a light band at shoulder height, arms straight. Pull the band apart until it touches your chest, squeezing your shoulder blades back, then return slowly. 15-20 reps. Great for balancing out a rounded posture. See my band pull-apart guide for grip options.

7. Side-lying or band external rotation

With your elbow tucked at your side and bent to 90 degrees, rotate your forearm outwards against a light band or a small dumbbell, then lower with control. 12-15 reps per side. This strengthens the rotator cuff, which helps keep the shoulder stable as you gain range. More detail in my external rotation exercise post.

8. Doorway pec stretch

Place your forearm on a door frame with your elbow at shoulder height and step gently through until you feel a stretch across the front of your chest. Hold for 30 seconds per side, breathing slowly. Tight pecs pull the shoulders forward, so this pairs well with the upper back drills.

Shoulder mobility routine before pressing

Use this before bench press, overhead press or push-ups. It takes about 6 minutes and is designed to warm you up, not tire you out.

1. Cat-cow x 8
2. Open book rotation x 6 per side
3. Wall slides x 10
4. Band pull-aparts x 15
5. Band external rotation x 10 per side

Then do 2-3 light warm-up sets of your first pressing exercise. For a full pre-session plan, my guide on how to warm up before lifting puts this into a complete warm-up.

Shoulder mobility exercises for desk workers

If you sit for long stretches, little and often works better than one long session. Try this mini routine 2-3 times across the working day. It takes 3 minutes and most of it can be done in an office.

• Seated thoracic rotation: sit tall, arms crossed, rotate to each side x 8.
• Doorway pec stretch: 30 seconds per side.
• Wall slides: x 10.
• Shoulder blade squeezes: pull your shoulders back and down, hold 3 seconds, x 10.

Then do the floor drills (thread the needle, open book, foam roller) in the evening or before training. If neck stiffness comes with the shoulder tightness, my post on desk stretches for office workers has extra options.

Want help with this? Mobility drills work best when they target your specific restriction, and that is hard to judge on your own. In a 1-to-1 session at SYP Fitness I check how your shoulders and upper back actually move, then build mobility and strength work around it. Book a free consultation to get started.

How often to do shoulder mobility work

Daily is ideal for the short desk routine. The longer floor routine works well 3-4 times a week. Expect to notice easier overhead reaching within a couple of weeks of consistent work, though everyone is different. Mobility gains stick best when you also strengthen the new range, so keep pressing, rowing and pulling in your weekly training.

A word of caution: these drills are for general stiffness. If you have shoulder pain at night, weakness when lifting your arm, pain after a fall, or pins and needles down the arm, see your GP or a physio before doing mobility work. My article on exercises for shoulder pain covers when to get it checked. If you live near the studio and want hands-on coaching, I also work with clients as a personal trainer in Highgate.

Frequently asked questions

How long does it take to improve shoulder mobility?

Many people feel looser straight after a session, but lasting change usually takes a few weeks of regular practice. Doing a short routine most days, plus strength work that uses your full range, tends to give the best results. Progress depends on how long you have been stiff, how much you sit and how consistent you are.

Can poor posture cause tight shoulders?

Spending long periods rounded over a desk can contribute to a stiff upper back and tight chest, which often makes shoulders feel restricted. Posture is less about holding one perfect position and more about changing position often. Regular movement breaks, mobility drills and strengthening your upper back all help.

Should I stretch or strengthen tight shoulders?

Both. Stretching and mobility drills improve the range you can reach, while strengthening helps you control and keep that range. Exercises like external rotations, band pull-aparts and rows are as important as stretches. A routine that only stretches often gives short-lived relief.

Is it OK to do shoulder mobility exercises every day?

Yes, gentle shoulder mobility exercises are generally safe to do every day for most healthy adults. Keep them pain-free and controlled, without forcing the end range. If a drill causes sharp pain or symptoms that last afterwards, stop it and get your shoulder assessed by a GP or physio.
