Pregnancy Stretches for Back and Hip Pain

Back pain and hip pain during pregnancy are usually discussed as separate problems, but they're closely connected. The postural changes that come with a growing bump — your pelvis tilting forward, your lower back arching more deeply, your centre of gravity shifting — affect the back and hips simultaneously. Tight hip flexors pull on the lower back. A stiff lower back changes how load is distributed through the hips. Addressing one without the other is why a lot of pregnancy stretching advice only gets you halfway there.

This routine targets both areas together. It takes around ten minutes, requires no equipment beyond a yoga mat or folded blanket, and is safe from the second trimester onwards for women with uncomplicated pregnancies. Done consistently once or twice a day, most women notice a meaningful reduction in tension within the first week.

As always, check with your midwife or GP before starting a new exercise routine during pregnancy. If you have diagnosed pelvic girdle pain or symphysis pubis dysfunction, speak with a women's health physiotherapist before trying these as some movements need to be modified.

Why back and hip pain tend to arrive together during pregnancy

Two hormonal and postural shifts drive most of the back and hip discomfort from the second trimester onwards.

The first is relaxin. This hormone loosens the ligaments throughout your pelvis in preparation for birth, which is necessary but also reduces the stability of your hip joints and sacroiliac joints. Less stability means the surrounding muscles have to work harder to compensate, and that sustained muscular effort produces the deep aching tension that many pregnant women feel in the hips and lower back, particularly at the end of the day or after periods of sitting.

The second is postural change. As your bump grows, your pelvis tilts forward and your lower back increases its curve to compensate. This shortens and tightens the hip flexors at the front of the hip and overloads the muscles of the lower back. Stretching that specifically addresses both the front of the hip and the lower back is more effective than targeting either in isolation.

The routine: five stretches, ten minutes

Work through these in order. Move slowly, breathe through each stretch, and aim for gentle sustained release rather than pushing to the edge of your range.

1. Hip flexor lunge stretch

This is the most important stretch in the routine for pregnancy back pain. Tight hip flexors are one of the main drivers of the lower back tension that builds through the second and third trimesters, and this stretch addresses them directly.

Come onto one knee on your mat with the other foot forward, creating a lunge position. Your front knee should be directly above your ankle. Keeping your torso upright, gently shift your weight forward until you feel a stretch at the front of your back hip and thigh. Place your hands on your front knee for support and balance. If you need more stability, rest one hand on a chair beside you.

Hold for 20 to 30 seconds on each side. You should feel the stretch in the front of the hip and inner thigh of the back leg, not in your lower back. If you feel it in your lower back, reduce how far you shift your weight forward.

2. Thread the needle

Thread the needle releases tension in the thoracic spine and the muscles of the mid and upper back that tighten as your posture changes in pregnancy. It also gently opens the hips.

Come onto your hands and knees with wrists under shoulders and knees under hips. Take one arm and slide it along the floor under your body, allowing your shoulder and the side of your head to lower toward the mat. Your other arm stays planted for support. You should feel a rotation through your upper back and a gentle opening in the shoulder.

Hold for 15 to 20 seconds on each side. Breathe steadily and let the weight of your arm deepen the stretch gradually rather than forcing it. Come back to hands and knees slowly between sides.

3. Supported lateral hip stretch

This targets the outer hip and the iliotibial band, which tightens significantly during pregnancy as your gait and posture change.

Stand beside a wall or sturdy chair and place one hand on it for support. Cross your outside foot in front of your inside foot. Lean your hips gently away from the wall, keeping your feet planted, until you feel a stretch along the outside of the hip closest to the wall. Keep your weight even through both feet and your torso upright.

Hold for 15 to 20 seconds on each side. This stretch is particularly useful during the day when getting down to the floor feels like too much effort.

4. Kneeling hip circle

This movement releases tension in the hip joints and the muscles around the sacrum and lower back through gentle, controlled rotation rather than a static hold.

Come onto your hands and knees in the same position as thread the needle. From here, draw slow, wide circles with your hips, moving in one direction for five circles and then reversing. Keep the movement smooth and controlled rather than large and forced. You should feel a releasing sensation across the lower back and into the hips.

This is one of the most instinctive movements in pregnancy — many women find themselves doing a version of it spontaneously during labour. Five circles in each direction is enough.

5. Supine piriformis stretch (with modification)

The piriformis sits deep in the buttock and is a common contributor to hip pain and sciatica during pregnancy. This is a modified version of the seated piriformis stretch suitable for women who find sitting in a chair uncomfortable.

Lie on your back on the mat — after 28 weeks, keep this brief and roll onto your side afterward rather than lying flat for an extended period. Bend both knees and place both feet flat on the floor. Cross one ankle over the opposite knee, creating a figure-four shape. Gently press the crossed knee away from you and flex your foot to deepen the stretch. You should feel it in the buttock of the crossed leg.

Hold for 15 to 20 seconds on each side and then roll onto your side to come up. If lying on your back is uncomfortable at any stage, the seated version from a chair is equally effective.

Building the routine into your day

Consistency matters considerably more than duration. Ten minutes done every day produces better results than a longer session done occasionally when you remember.

Morning is a useful time because joint stiffness and hip tension tend to be highest after a night of relatively limited movement. Before bed is equally useful for releasing the tension that builds through the day. If you can do both, even better.

If you're short on time, the hip flexor lunge and the kneeling hip circle cover the most ground in the least time. Start there if the full routine feels like too much on a given day.

When to stop and seek advice

Stop any stretch that causes sharp pain, produces pain in your pubic bone, or makes your hip or lower back feel worse rather than better. Mild stretching sensation is normal. Pain is not.

If hip or lower back pain is severe, persists through the day rather than easing with movement, or is accompanied by pelvic instability or pain in the pubic area, ask your GP or midwife for a referral to a women's health physiotherapist. These are signs of pelvic girdle pain or symphysis pubis dysfunction that benefit from specific assessment and management rather than general stretching.
