The Hip Flexor (Psoas) Must Always Be Intensively Stretched for All Back Pain.
Summary
The hip flexor (psoas) is often not shortened in back pain, but weak or overloaded – intensive stretching can additionally irritate the tissue. Targeted strengthening of psoas and core is often more effective than blanket static stretching.
Mythbuster: The Hip Flexor (Psoas) Must Always Be Intensively Stretched for All Back Pain.
The Myth
The hip flexor (psoas) must always be intensively stretched for all back pain.
What the Evidence Says
Often a painful hip flexor is not "shortened," but weak or overloaded. Excessive stretching can further irritate the tissue. Often targeted strengthening of the psoas and the surrounding core musculature is more effective than purely static stretching.
Practice: Concrete Implementation
The myth "always stretch intensively" often leads in practice to those affected doing exactly the opposite of what helps the tissue. Instead of stretching across the board, the rule is: classify first, then dose. A painful hip flexor is often not shortened, but weak or overloaded – excessive static stretching can further irritate the tissue. The following examples show how to implement this in everyday life and training.
Example A — Weekly Plan (Classification Instead of Reflex)
Goal: Control load and recovery of the hip flexor so that strength and tolerance increase without irritating the tissue.
| Day | Focus | Concrete Unit | Duration |
|---|---|---|---|
| Mon | Psoas/Hip Strength | Hip Flexor Strengthening (e.g. Standing March, Dead Bug, Copenhagen variant light) | 10–12 Min |
| Tue | Core & Glutes | Anti-rotation (Pallof), Glute Bridge, Side Plank | 10 Min |
| Wed | Daily Life/Walking | Walk, Stairs, no targeted stretching | 20–30 Min |
| Thu | Psoas/Hip Strength | Like Mon, slightly progressive increase | 10–12 Min |
| Fri | Mobility dosed | Gentle hip extension only if needed, short and pain-free | 5 Min |
| Sat | Core & Glutes | Like Tue | 10 Min |
| Sun | Recovery | Light movement, no intensive stretching | – |
Important: Intensive static stretching is not mandatory here, but only optional and short – and only if it does not provoke symptoms.
Example B — Execution & Coaching Cues
Strengthening Instead of Reflex Stretching:
- Standing March: Stand upright, slowly lift one knee to hip height, keep pelvis stable. Cue: "Engage abs slightly, keep ribs over pelvis, do not arch the back."
- Dead Bug: Supine position, arms and legs at 90-degree angle. Cue: "Press lumbar spine gently into the floor, slowly extend one leg without the back lifting off."
- Pallof Press: Stand sideways to the cable band, press band forward. Cue: "Pelvis and ribcage remain parallel, nothing rotates."
If You Stretch Anyway:
- Only if needed, not daily as mandatory.
- Hold short (approx. 20–30 seconds), pain-free.
- Cue: "Only to the first feeling of tension, not into pain."
- If complaints increase: Pause stretching and prioritize strengthening.
Example C — Microcycle (4 Weeks)
| Week | Focus | Dosage |
|---|---|---|
| 1 | Acclimatization | 2×/Week Psoas/Hip strength, very light, 2 sets |
| 2 | Build-up | 2–3×/Week, 3 sets, slow repetitions |
| 3 | Progression | 3×/Week, slightly increase load/repetitions |
| 4 | Consolidation | 2–3×/Week, maintain technique, stretch only if needed |
Accompanying: Check daily load (long sitting, lots of stair climbing, running volume). Often the cause lies in the sum of the load, not in "too short" muscles.
Ideal: You classify complaints, train psoas and core specifically, and stretch only situationally and pain-free.
Good enough: You replace daily intensive stretching with 2–3 short strength units per week.
First step: You leave out intensive stretching for one week and observe how the complaints change.

Do I always have to stretch the hip flexor for back pain?
No. A painful hip flexor is often not shortened, but weak or overloaded. Blanket intensive stretching can further irritate the tissue. Usually, targeted strengthening of the psoas and the surrounding core musculature, combined with adjusted daily load, is more sensible.
When can stretching the hip flexor still be sensible?
Stretching can be situationally sensible if it remains pain-free, is only dosed short (approx. 20–30 seconds), and does not provoke symptoms. However, it should not be understood as a daily mandatory program for all back pain. If complaints occur during stretching, strengthening should be prioritized.
What is the most important alternative to intensive stretching?
Targeted strengthening: Exercises like Standing March, Dead Bug or Pallof Press train psoas and core, improve load tolerance and stabilize the pelvis. Accompanying, it is worth checking the daily load (long sitting, stairs, running volume), as the cause often lies in the sum of the load.
