Fascia release for the hips: what rolling, ball release and stretching do for the glutes, hip flexors and outer hip

Rolling buys a few minutes of range

Across 26 trials, foam rolling gave a short-term gain in range of movement about the same as stretching. At the hip, the extra range had gone within 10 to 20 minutes.

It doesn't release fascia

Neither rolling nor stretching changed the stiffness of the IT band (the iliotibial band down the outside of the thigh) in a trial, dense fascia needs far more force than a roller applies to change shape, and the effect runs mainly through the nervous system.

Sources 4, 5, 6

Lasting range comes from stretching and strength

Rolling programmes improved range more when they lasted over 4 weeks, stretching programmes did at least as well, and strength training through a full range improved range as much as stretching in 11 trials.

Sources 7, 8, 9

Hip pain needs exercise more than release

For hip osteoarthritis, NICE (the National Institute for Health and Care Excellence) says to consider hands-on therapy only alongside exercise. For outer hip pain, education and exercise beat a steroid injection in a trial of 204 people.

Roll safely

Roll the outer part of the buttock and the front of the thigh slowly. With a ball, keep it moving and off the middle of the buttock, where the sciatic nerve runs: one case report describes a nerve injury there. Keep balls out of the groin and belly, and skip rolling a sore outer hip.

Emotions aren't stored in your hips

We found no study showing that emotions are stored in the hips, and body-based trauma therapies have only preliminary evidence. Feeling emotional during slow stretching is common and normal.

Sources 13, 14

The areas people mean

The buttocks (the gluteal muscles, with the piriformis deep under them); the hip flexors at the front of the hip (the iliopsoas, and the rectus femoris of the thigh); the outer hip, where the buttock muscles' tendons attach to the bony point at the side of the hip, under the IT band; and the inner thigh. Our muscle guides cover each one.

Tight isn't the same as short

Hips can feel tight without the muscles being short. Our psoas and hip flexor pain guides explain why a tight feeling at the front of the hip hasn't been shown to cause back pain, and why strength work matters as much as stretching.

What rolling changes

Rolling improves range for a short time, mainly by changing how much stretch you can tolerate and how sensitive the area is. It doesn't lengthen or release fascia: the IT band's stiffness didn't change with rolling or stretching, and rolling the buttock muscles improved hip range more than rolling the IT band itself, which suggests the muscle, not the band, is what responds. Dense fascia such as the sheet down the outside of the thigh needs forces far beyond a roller to change shape.

The nerve in the buttock

The sciatic nerve runs through the middle of the buttock. In one case report, a woman injured it after self-massage there with a massage ball. A case report shows this can happen, not how often.

Hip pain that release won't fix

Osteoarthritis of the hip joint, where exercise is the main treatment; a painful tendon at the outer hip, where education and exercise work; pain that comes from the back, such as sciatica; and the causes in the warning signs below, such as a broken hip, a joint infection, and in children, hip problems that may only show as a limp or knee pain.

Rolling improves range for a short timeStrong evidence

A meta-analysis of 26 high-quality trials found foam rolling gave a large short-term gain in range against no exercise, the same as stretching. Vibrating rollers added nothing, and how long or how fast people rolled made no clear difference.

The extra range fades within minutesEmerging evidence

In 34 people, rolling the outer thigh 3 times for 20 seconds improved hip range straight away and at 3 minutes, but not at 10 minutes. In 25 trained men, rolling the front of the thigh for 60 or 120 seconds raised hip bending by about 19 degrees and hip extension by about 9, gains that had faded within 10 to 20 minutes; 120 seconds did more than 60.

Sources 2, 3

Where you roll mattersEmerging evidence

In 27 people, rolling the buttock muscles improved the hip's inward range by 14.8%, while rolling the IT band itself changed it by 2%. In 23 people, 2 minutes of rolling the front of the thigh changed hip extension by less than 2 degrees.

Sources 15, 19

Programmes over weeksEmerging evidence

In 11 studies (290 people, average age 24), rolling programmes improved range moderately, more when they lasted over 4 weeks. Rolling 5 times in a week improved a lunge stretch, and the gain had gone after a week off. Across 85 studies, stretching programmes and rolling programmes both improved range, with stretching better in programmes of 4 weeks or less, and in 11 trials (452 people) strength training improved range as much as stretching.

The IT band doesn't changeEmerging evidence

In 30 people, neither rolling nor stretching changed the IT band's stiffness on ultrasound. Our IT band guide explains why it barely stretches.

Hip osteoarthritisEmerging evidence

NICE recommends exercise and weight management first, and says to consider hands-on therapy only alongside exercise. In 35 people with mild to moderate hip osteoarthritis, 4 weeks of daily home rolling or vibration eased pain when walking more than exercise alone, with no other differences. A retrospective study found more people reached a meaningful drop in pain with rolling, but that kind of study can't show cause.

Sources 10, 21, 22

Outer hip painStrong evidence

In 204 people with a painful tendon at the outer hip, 14 sessions of education and exercise over 8 weeks helped 77%, against 58% after a steroid injection and 29% with wait and see, and stayed better at a year. Our outer hip pain guide has the plan, and advises skipping outer-thigh rolling while the bony point is sore.

Release added to strength workEmerging evidence

In a pilot trial of 16 people with IT band syndrome, adding myofascial release to hip strengthening eased pain a little more at 2 weeks. For back pain, hands-on release of the psoas added to physiotherapy didn't ease pain more in 40 people, and release of the diaphragm and iliopsoas eased pain at rest by about 2 points out of 10 more than a fake release in 42 people, measured at the end of treatment. Our psoas guide covers deep release.

Stretching the front of the hipEmerging evidence

In 26 active adults, a half-kneeling stretch with the pelvis tucked under lowered the hip flexors' resistance to stretch, while the usual lunge stretch barely changed it. The trial used 2 holds of 30 seconds.

The front of the thigh

Roll the front of the thigh for about 90 seconds a side, the move page's dose, staying off the kneecap and short of the crease at the top of the thigh. If you like pressure at the front of the hip, roll your thighs, not your belly, as our psoas guide puts it.

The inner thigh

Rest the inner thigh on the roller about halfway between the knee and the groin, for about 90 seconds a side, the move page's dose, and never roll hard into the groin crease.

The outer hip

Roll the outer thigh gently, if at all, and skip it if the bony point at the side of your hip is sore: that's usually a tendon problem, and education and exercise treat it. Rolling won't lengthen the IT band.

Sources 11, 4

Use the window

The extra range from rolling fades within 10 to 20 minutes, so stretch and strengthen straight after. For the front of the hip, the tucked half-kneeling stretch: 2 holds of 30 seconds each side, the dose from its trial.

Make it last

Rolling programmes did better over more than 4 weeks, and strength work through a full range improves range as much as stretching. Two or 3 sessions a week is our editorial starting point; the hip release routine below puts it together.

Where not to roll or press

• A leg that is swollen, red or darkened, or throbbing: it can be a clot (deep vein thrombosis), which needs an urgent check, not rolling.
• Varicose veins and bruises.
• The groin crease and the belly, where there are large blood vessels and a nerve. A man on blood thinners had a large bleed in his tummy wall after using a massage gun there, and our psoas guide explains the risks of deep belly pressure.
• The middle of the buttock, with a ball.
• The bony point at the side of the hip, while it's sore.

Sources 27, 28, 12, 11

Expert cautions for rolling

In an expert consensus of 37 researchers, open wounds and broken bones were reasons not to roll, and inflammation, a clot, a bone infection or bone forming in a muscle after an injury were reasons for caution.

Ask first

Keep the pressure light if you take blood thinners, which make bruising more likely, and ask first if you have osteoporosis or a nerve condition such as peripheral neuropathy: the NHS lists these among the reasons hands-on treatments may not be safe.

Pregnancy and hip replacements

In pregnancy, don't press on your bump, and after the first trimester keep time lying flat on your back short. After a hip replacement, follow your surgical team's limits before deep bends and crossed-leg stretches, and before rolling near the scar.

"Emotions and trauma are stored in your hips"Mixed evidence

We found no study showing that emotions are stored in the hips. Body-based trauma therapies have only preliminary evidence of mixed quality: a review of somatic experiencing found 16 studies, and a review of trauma releasing exercises found 22 studies whose methods weren't consistently rigorous. Feeling emotional during slow stretching and breathing is common and normal; that's your nervous system responding in the moment, not a stored memory leaving the tissue. Our psoas guide checks the same claim about the psoas.

"Rolling breaks up fascia and lengthens the IT band"Mixed evidence

The IT band's stiffness didn't change with rolling or stretching, rolling it barely changed hip range while rolling the buttock muscles did, and dense fascia doesn't change shape at these forces.

"Tight hip flexors cause back pain, so release them"Mixed evidence

Hands-on psoas release added little to physiotherapy for back pain in two small trials. Our psoas and hip flexor pain guides explain why tight isn't the same as short, and why strength work matters.

"Roll your outer hip to fix outer hip pain"Mixed evidence

Outer hip pain is usually a tendon problem, and education and exercise beat a steroid injection for it. Our outer hip pain guide advises skipping outer-thigh rolling while the bony point is sore.

"Fascia release slims your hips or waist"Mixed evidence

We found no trial of fascia release for body shape. Two reviews of Chinese massage (tuina) trials, all run in China and added to diet, exercise or medicine, found waists 3.6 to 6.2 cm smaller than without massage, but none of the trials was blinded and the certainty was low to very low. Our fascia blasting verdict covers the cellulite claims.
