Muscles
Erector spinae stretches for posture and hinge comfort.
The erector spinae run along the spine and support extension, posture and controlled hinging. Flexor gathers guided back mobility and gentle lengthening here so prolonged sitting and lifting days feel less stiff through the trunk.
About Erector Spinae
Posture and hinge endurance
The erector spinae help you extend the spine and hold a steady trunk under load. Desk time and repetitive hinging can leave them feeling tight or fatigued, so mixing gentle mobility with light hinge practice tends to support comfort better than aggressive end-range flexion alone.
Move the back with control
Cat-camel, supported hinges and light good-morning patterns keep the erectors working through a comfortable range. Stay out of sharp pain, keep breaths easy, and pair mobility with core and hip work so the lower back is not doing every job alone.
Move comfortably
Keep spinal mobility within a comfortable range and avoid loading painful end positions. This is general fitness guidance, not treatment — seek professional advice for back pain or an injury.

Common questions
How do I stretch the erector spinae?
Gentle flexion and hinge patterns — such as a rounded child's pose, seated forward fold with soft knees, or a controlled good-morning — lengthen the back extensors when kept mild. Avoid forcing end range, especially if the lower back feels irritable, and explore the guided spine and lower-back exercises below.
Why does my mid or lower back feel tight after sitting?
Long sitting keeps the trunk in one position, so the erectors can feel stiff when you stand or hinge again. Short mobility breaks, light hinge practice and hip mobility usually help more than aggressive stretching. Flexor's desk and lower-back routines make that habit easier to keep.
