🏃♂️ Lower back stiffness after running? You’re not alone.
That tight, stiff feeling in your low back post-run is common — but it’s not always a “back problem”.
Here are the usual suspects 👇
🔹 Hip stiffness – limited hip extension = your back does the extra work
🔹 Fatigued glutes & core – the low back picks up the slack late in the run
🔹 Poor load tolerance – your back isn’t used to the volume (yet)
🔹 Running form changes with fatigue – hello over-stride & arching
🔹 Sudden training changes – speed, hills, or mileage jumps
💡 What helps?
✔️ Easy mobility (hips + thoracic spine)
✔️ Progressive running load (no big jumps)
✔️ Glute & trunk strength (anti-extension / anti-rotation)
✔️ Cool-down walks or easy jogs
✔️ Don’t panic — stiffness ≠ damage
⚠️ If stiffness becomes pain, lingers >24–48hrs, or affects your stride, get it checked.
