Chair Lower Back Stretch
This stretch has you sit in a chair, reach your arms forward and down, and round your back to lengthen your lats and lower back at the same time. It's a quiet, low-effort stretch you can do right at a desk, which makes it one of the easiest ways to counter the slightly hunched, seated posture most of us fall into during a long day.
Why it works
Your lats run from your upper arms down to your pelvis, so reaching your arms forward while you round your back stretches them along nearly their whole length instead of just at one end. Rounding your spine at the same time lengthens your lower back muscles, which tend to sit in a shortened, slightly arched position through hours of sitting upright. Doing both together in one shape is efficient: the arm reach pulls on your lats from above while the rounded spine pulls on your lower back from below, so one seated position covers two different muscle groups that both get tight from the same seated posture.
Set up
- Sit toward the front edge of a stable chair.
- Plant your feet flat on the floor, roughly hip-width apart.
- Take a breath in to prepare before you begin reaching forward.
How to do it
- Reach both arms forward and down toward the floor or the legs of the chair.
- Round your back as you reach, letting your head drop gently between your arms.
- Sink into the stretch, feeling it along your lats and lower back.
- Hold the position, breathing steadily.
- Roll back up slowly to sitting, stacking your spine one section at a time.
Form cues
- Reach forward and down, not just down toward your feet.
- Let your back round instead of staying flat as you reach.
- Relax your neck and let your head hang rather than holding it up.
- Come back up slowly, don't snap upright.
Breathing: Exhale as you fold forward into the stretch, and breathe slowly while you hold it before inhaling on the way back up.
Common mistakes
Keeping your back flat while reaching forward, which limits how much your lower back actually stretches.
Fix: Let your spine round as you reach, a curved back is what lengthens the muscles you're targeting here.
Snapping back upright quickly after the stretch.
Fix: Roll back up slowly, one section of your spine at a time, to avoid a head rush or a jolt on a freshly stretched back.
Tensing your neck and shoulders while reaching forward.
Fix: Let your head and neck relax completely, holding tension there works against the point of the stretch.
How to program it
- This is a gentle stretch with no fatigue cost, so it fits well multiple times a day, especially during long stretches of sitting.
- Hold for 20 to 30 seconds, two or three times, rather than forcing one long hold.
- It works well as a quick break during desk work or as part of a cool-down after training your back.
Safety notes
- Use a stable chair that won't roll or tip as you reach forward.
- Stretch to a point of mild tension, not sharp pain.
- Move slowly in and out of the position if you have any dizziness with head-down positions.

Frequently asked questions
How long should I hold the chair lower back stretch?
20 to 30 seconds, repeated two or three times, is a good target. It's a gentle stretch, so there's no need to force one long hold.
Can I do this stretch multiple times a day?
Yes. It's low-effort enough to repeat several times during a day of sitting, and many people use it as a quick reset between desk tasks.
Why does this stretch target my lats and not just my lower back?
Your lats run from your arms down to your pelvis, so reaching forward while you round your back stretches them along with your lower back muscles in the same position.
What can I pair this stretch with?
The chair upper body stretch works the front of your torso and shoulders, so doing both gives you a balanced stretch for the front and back of your upper body.
