Middle Back Stretch
The middle back stretch has you round your spine forward while reaching your arms out, opening up the space between your shoulder blades and the muscles that run along your upper spine. It's a simple, no-equipment stretch that targets the tension that builds up between your shoulder blades from sitting or rounding forward for long stretches. A few slow reps or a single held stretch can noticeably ease that tight, achy feeling across your upper back.
Why it works
Your middle back muscles spend a lot of the day working isometrically to keep you upright, especially if you sit hunched over a desk or a phone, and that constant low-level tension is what builds into stiffness. Rounding your spine forward and reaching your arms away from your body does the opposite of that upright, braced posture, lengthening the muscles between your shoulder blades and giving them a genuine break from holding a fixed position. Because the movement also draws in your abdominals and lats a little, it opens the whole upper back rather than just one narrow strip of muscle.
Set up
- Sit or kneel on the floor, or stand with a slight bend in your knees.
- Clasp your hands together in front of you, or hold onto something stable like a doorframe or pole.
- Round your upper back gently as you begin, rather than starting from a fully arched position.
How to do it
- Push your hands away from your body while rounding your upper spine.
- Let your shoulder blades spread apart as your chest curls slightly inward.
- Hold the stretch for 20 to 30 seconds, breathing steadily.
- Release slowly, letting your spine return to a neutral position.
- Repeat two to three times, holding a bit longer each round if it feels good.
Form cues
- Round from the upper spine, not just the shoulders.
- Push the hands away to spread the shoulder blades.
- Keep breathing steadily through the hold.
- Release slowly, don't snap back to neutral.
Breathing: Breathe slowly and steadily throughout the hold; a held breath makes the muscles tense instead of release.
Common mistakes
Rounding only the shoulders forward instead of the upper spine.
Fix: Focus on curling your whole upper back, letting the stretch spread across your shoulder blades rather than just your shoulder joints.
Bouncing in and out of the stretch instead of holding it still.
Fix: Ease into the position and hold it steady; a static stretch works best without repeated bouncing.
How to program it
- Two to three rounds of 20 to 30 seconds is plenty for most people, and it's gentle enough to repeat daily.
- Works well any time your upper back feels tight, whether that's after a long stretch at a desk or as a cool-down after upper body training.
Safety notes
- Stop and ease off if you feel any sharp pain rather than a gentle stretch; a mild pulling sensation is the goal, not discomfort.
- Keep the movement slow and controlled, especially if your upper back feels particularly stiff that day.

Frequently asked questions
How long should I hold a middle back stretch?
20 to 30 seconds per round is enough to feel real release, and two to three rounds covers most people's needs.
What can I do instead of the middle back stretch without any equipment?
The cat stretch on your hands and knees rounds the same part of your spine and works just as well with no equipment at all.
Why does my middle back feel tight even after stretching?
Ongoing tightness there is usually more about posture and how much time you spend rounded forward or upright without a break than about a single stretch. Regular short breaks to move through the same rounding motion tend to help more than one long stretch session.
