How to fix Sway Back Posture

What is Sway back posture?

sway back posture

The Sway Back Posture is where the pelvis is pushed in front of the line of the ankle.

As a result – the torso will “sway back” in the attempt to compensate for the forward shift of the pelvis.

characteristics of Sway back posture

(Note: This is the general presentation of someone with the typical Sway Back Posture. It is not uncommon to see slight variations.)

What causes Sway back posture?

a) Tight hamstrings

Tight hamstrings can tilt the pelvis backwards (posterior pelvic tilt) and drive the pelvis forwards.

Quick test: Do you have tight hamstrings?

hamstring tightness test


  • Lie down on your back.
  • Hold the back of the knee and bring your hip to 90 degrees of flexion.
  • Whilst keeping your toes pointed, straighten your leg as much as possible.

Results: If you are not able to straighten your leg in this position, then you likely have tightness in your hamstring muscle.

b) “Butt Gripping”

“Butt Gripping” refers to the over use and reliance of the glute muscles to stabilize the pelvis.

This can result in the pelvis being pushed into a forward position.

c) Hypermobility

Sway Back Posture can result from the hypermobility/excessive laxity of joints.

This is due to the body resting on the end ranges of the joint as opposed to muscles holding it in the correct position.

Quick test: Do you have Hypermobility?

Answer these questions:

  • Can you place your palms on the floor whilst standing with knees completely straight?
  • Do your knees hyperextend? 
  • Do your elbows hyperextend?
  • Can you pull your thumb to touch the front of your forearm?
  • Can you pull your little finger backwards to 90 degrees?

Results: If you answered “Yes” to most of these questions, it suggests that you may have a degree of Hypermobility.

The best way to address Hypermobility is to focus on strengthening the muscles that support the joints.

d) Slouched thoracic spine

slouched posture

If the upper back is locked in a hunched position, your pelvis may compensate by driving the hips forwards.

This is the body’s attempt to keep the head in a more up right position to maintain a horizontal line of sight.

e) Bad habits

How you position your body throughout the day can significantly effect your posture.

Main habits that lead to Sway Back Posture:

  • Sleeping on your stomach
  • Poor posture when sitting
  • Standing with your hips pushed forwards.

How do you know if you have Sway back posture?

1. Take a side profile shot of your standing posture

Make sure that:

  • Your clothing attire allows clear vision of your body.
  • The photo is taken at hip level.
  • The head to the feet are completely visible.

2. Locate your land marks

test sway back posture

  • Greater trochanter (Hip): This is the bony prominence that sticks out on the side of your hip.
  • Lateral malleolus (Ankle): This is the bony bit that sticks out at the outside of your ankle.

3. Compare the alignment of these 2 landmarks

In the ideal posture, you should be able to draw a straight line between the greater trochanter and lateral malleolus.

If you have Sway Back Posture: The Greater Trochanter will be in front of the line of the Lateral Malleolus.

Sway back posture vs Anterior pelvic tilt

anterior pelvic tilt vs sway back posture

It is very common for people to get confused between having a Sway Back Posture versus having an Anterior Pelvic Tilt.

It is important to know the difference between these postures as their respective exercises are different!

(Performing the right exercise for the wrong diagnosis will not help you!)

The 2 main differences being that in a Sway Back Posture:

1. The center of the hips are in front of the line of gravity.

2. The pelvis is in a posterior pelvic tilt relative to the upper leg bone.

muscles involved with sway back posture

The following muscles will need to be addressed:

a) Tight muscles:

  • Hamstring
  • Gluteal group
  • Internal Obliques
  • Upper Abdominals
  • Anterior shin muscles

b) Elongated muscles:

  • Hip flexors
  • External oblique
  • Erectors spinae muscles in the thoraco-lumbar junction

  • Whilst anchoring the ankle joint down, pull the fore foot towards you.
    • (Include the toes!)
  • Aim to feel a stretch on the out side of the ankle.
  • Hold for 30 seconds.
  • Repeat 3 times.

2. Activate hip flexor group (iliopsoas)

Aim: To increase the strength of the hip flexor muscle group.

a) Sitting hip flexion (on the chair)

sitting hip flexion


  • Sit up right on the edge of a chair.
  • Without moving your pelvis, lift knee as high as possible.

  • Practice pushing your hips backwards to a neutral.
  • Repeat 30 times.

3. Gluteal group (aka the “butt muscles”)

Weakness in the gluteal muscles can lead to over-activity/tightness of the hamstrings.

a) Hip extension

hip extension in standing


  • Whilst standing upright, extend your leg backwards until you feel your gluteals contract firmly.
  • Do not rotate your body.
  • Hold for 5 seconds.

4. Eccentric Strengthening of Hamstrings

Eccentric strengthening involves the contraction of a muscle whilst it is ELONGATING.

In other words: It is a combination of strengthening + stretching at the same time.

a) Dead lift exercise

eccentric dead lift


  • Whilst standing, hold onto an appropriate amount of weight.
    • (… it should be a moderately heavy weight that you can control)
      • And yes, I do realize I am holding a yoga mat (haha)
  • Upper hamstring: Place a slightly bent knee in front of you.
  • Lower hamstring: Place a straight knee in front of you.
  • Shift most of your weight to the front leg.
  • Slowly lower the weight by hinging at the hips.
    • Keep your lower back completely straight.
    • Aim to feel a pulling sensation in the hamstring region before returning to the starting position.
    • Keep the weight close to your body.
    • This lowering phase should take 3-5 seconds.
  • Return to starting position.
    • Do not thrust your hips forwards.
  • Perform 10 repetitions.

5. Thoracolumbar junction

Aim: To increase the extension of the joints in the thoracolumbar junction.

a) Cobra pose

thoracolumbar extension exercise


  • Lie on your stomach.
  • Prop your torso up onto your forearms.
  • Lift up your torso as high as you can whilst keeping the belly button in contact with the floor.
  • Aim to feel tension specifically in the middle of your spine. (see above)
    • Do not arch back too far as you will feel the tension at the base of the lower back.
  • Repeat 20 times.

6. Upper abdominal tightness

Tightness in the upper abdominal region can lock the torso into a flexed position.

a) Upper abdominal release

upper abdominal release


  • Lie on the floor.
  • Position your upper abdominal region over a massage ball.
  • Apply an appropriate amount of body weight on top of the ball.
  • Whilst positioning the massage ball in the upper abdominal region, place your body weight on top of the ball. (see above)
  • Make sure that you keep your abdominal muscles relaxed.
    • Tip: Taking deep breaths in/out will help keep your abdominal region relaxed.
  • Hold each position for at least 30-60 seconds.
  • Proceed to move the massage ball over to the other areas as indicated above.

(Note: DO NOT place excessive amount of pressure into your abdominal region! There are many sensitive organs in the area which can be subject to damage when too much pressure is applied.)

b) Intercostal release


  • Locate ribs 6-10 at the front of your lower chest.
    • (If you place your palms on the ribs below the nipple region, you should be in the right area.)
  • Locate the intercostal muscles which are situated between the rib bones.
  • Firmly press into these muscles.

c) Cobra pose

upper abdominal region stretch


  • Lie on your stomach.
  • Place your hands on the ground far in front of you.
  • Lift up your torso as high as you can whilst keeping the belly button in contact with the floor.
  • Aim to feel a stretch in the upper abdominal region.
  • To increase the stretch: Take a deep breath in and push your belly outwards.
  • Hold for 30 seconds.

d)  Lower rib upward tilt


  • Sit down on the edge of a chair.
  • Lock your pelvis in a neutral pelvis.
  • Without moving your pelvis, tilt your lower ribs upwards.
    • Create some extension in the upper lumbar region.
  • Hold for 5 seconds.
  • Repeat 30 times.

7. Core strengthening exercises

You will need a strong core to maintain good posture.

a)  Anterior pelvic tilts

pelvic tilt in sitting


  • Sit on an exercise ball or a chair.
  • Sit upright. Think long and tall throughout the spine.
  • Proceed to tilt the pelvis forward.
  • Aim to feel a contraction in the muscles of the lower back.
  • Hold for 5 seconds.
  • Repeat 30 times.

b)  Single leg balance


  • Stand on one foot.
  • Make sure that your hips are in line with the ankles.
  • Maintain balance for 30 seconds.
  • Repeat on other side.

c)  Plank



  • Get into the plank position. (see above)
  • Position your pelvis in a neutral position.
    • Engage the core and glutes to stabilize the pelvis.
  • Make sure your lower back does NOT sink in. (This can make Sway Back Posture worse!)
  • Hold for 30 seconds.
  • Repeat 3 times.
  • Progression: Place a weight on top of your pelvis.

d) Dead bug

dead bug exercise


  • Lie on your back with both of your knees bent in the air. (Position 1)
  • Engage your core and abdominal group by gently drawing in your belly button.
  • Keep your pelvis in a neutral position.
    • There should be a slight arch in your lower back.
    • Maintain this arch throughout exercise.
  • Slowly lower the opposite arm/leg. (Position 2)
  • Repeat 10 times.
  • Progression: Add 5-10 second holds in Position 2.

8. Addressing other postures

If you still have Sway Back Posture after trying out all of the mentioned exercises, you may need to address other parts of your posture.

a) Hunchback Posture

A Hunchback posture (also known as having a thoracic kyphosis, rounded back or humpback) is where the upper back is excessively rounded forward.

For more information, check out this blog post:

b) Rounded Shoulders

Having Rounded Shoulders is when the resting shoulder position is in front of the mid line of the torso.

For more information, check out this blog post:

c) Forward Head posture

forward head posture

A Forward Head Posture is where the position of the head is in front of the mid line of the torso.

9. How to stand

Now that you have completed all of the exercises, is it important that you learn how to stand properly. (Otherwise the Sway Back Posture will persist!)

Step 1: Stack pelvis on top of the ankles by pushing hips backwards

Keep the greater trochanter and lateral malleolus in line with each other.

Step 2: Return pelvis to neutral

If your pelvis is still in a bit of posterior pelvic tilt, you will need to tilt your pelvis forwards until it is in a neutral position.

The neutral position of the pelvis is when the Anterior Superor Iliac Spine (pointy bone at the front of hip) is slightly lower than the Posterior Superor Iliac Spine (pointy bone at the back of hip).

Step 3: Re-position your rib cage

Without moving your pelvis, tilt your lower chest upwards. (… but not too far that you flare your ribs!)

Step 4: Re-position shoulders

Gently roll your shoulders back and down.

Step 5: Elongate/retract neck


This will prevent your neck from poking forward.

How do you feel in this new position?

Yes, it will feel weird.

But just remember – you have most likely been standing with your Sway Back Posture for many years and any change to the norm is going to feel different.

Be aware of your posture.

Try to incorporate this new posture throughout your day to day activities.

10. Address bad habits

If you have any of the following bad habits, you will need to address these as well.

a) DO NOT stretch the hip flexors

sway back posture hip flexor stretch

In the Sway Back Posture, the hip flexor muscle group is already in a lengthened position.

Stretching the hip flexors will further lengthen an already elongated muscle and potentially make the issue worse.

If you are feeling tight in this area, you are most likely feeling “stretch tension”.

(Think of an over stretched rubber band. Is it truly tight or is does it have stretch tension?)

b) DO NOT sleep on the stomach

Sway back posture sleeping position

Sleeping on your stomach may encourage the Sway back posture.

This is particularly true if you sleep on a very soft mattress as this will allow your pelvis to sink forwards.

c) DO NOT sit with bad posture

When sitting, make sure that your pelvis is positioned right into the back of the chair.

This will reduce the amount of posterior pelvic tilt.

d) DO NOT stand like this


When standing, do not allow your hips to push forwards.

e) DO NOT over do abdominal crunches

exercises to avoid with sway back posture

Abdominal crunches may increase the dominance of rectus abdominus.

This may increase the forward curving of the upper back which is seen in the Sway Back Posture.

f) Dead lift technique

If you regularly perform deadlifts, make sure that you do not thrust your hips forwards at the end of movement.


The Sway Back Posture is characterized by the forward position of the pelvis. (… and the torso “swaying” backwards.)

The main causes being tight hamstrings, over-active glutes, hypermobility, bad habits and slouched postures.

The exercises mentioned in this blog post will help address the muscular imbalances associated with Sway Back Posture.
