Exercises for Deep Neck Flexors

What are the Deep Neck Flexors?

The Deep Neck Flexors are a group of muscles responsible for achieving and maintaining the ideal position of your head and neck.

It includes the following muscles: Longus Colli and Longus Capitis

They function together with the Deep Neck Extensors.

  • Lie down on your back.
  • Use a pillow underneath your neck/head if required.
  • Keep your knees bent and feet on the floor.
  • Nod your chin towards your chest.
  • Lift your head off the floor.
  • Time how long you can hold this position.

Results: If you can’t hold this position for at least 30 seconds, you have weak Deep Neck Flexors!

Alternatively – You can request your Health Professional to perform the Craniocervical Flexion Test on you.

Deep Neck Flexor Exercises

1. Release the Neck Muscles

Before you start the Deep Neck Flexor exercises, I suggest that you Release the muscles on the back of your neck.

Why? The muscles which are located at the back of the neck will tend to compensate for Deep Neck Flexor weakness.

a) Posterior Neck Release

  • Lie down on the floor.
  • Place a massage ball behind your neck.
  • Do not place the massage ball directly on any bony structure.
  • Apply an appropriate amount of weight.
  • Continue for 2 minutes each side.

Target area:

posterior neck release

2. How do you activate the Deep Neck Flexors?

It is vital to know how to activate the Deep Neck Flexors muscles properly.

Otherwise… you will end up recruiting and compensating with other neck muscles!

(NOTE: This is the most important part of this blog post! It is crucial that you completely understand what you should be feeling as you perform this activation exercise.)

DO NOT move onto the strengthening exercises until you get this right!

a) Deep Neck Flexor Activation

  • Lie down on your back.
  • Place a pillow underneath your head if it is more comfortable.
  • Flatten your tongue to the roof of your mouth.
  • Relax your breathing.
  • Keep your neck completely relaxed.
  • Nod your chin towards your chest.
  • Aim to feel a gentle muscular contraction in the back of your throat.
  • There should also be a lengthening sensation at the back of your neck.

Note: There should be no activation of the superficial neck flexors (Sternocleidomastoid and Anterior Scalenes) as you perform this exercise.

You can place your hand onto the front of the neck to monitor for this.

3. Deep Neck Flexor Strengthening Exercises

The follow exercises are listed in order of difficulty.

Make sure to focus on performing the exercise correctly before progressing to the more difficult ones.

Challenging Exercises

Once you have developed an adequate amount of strength/endurance in the Deep Neck Flexors, progress to these more challenging exercises.

h) Lean Back

  • Sit down on a chair with a backing.
  • Slide your hips down the seat.
  • Lean your torso backwards.
  • (The more you lean your torso backwards, the more demand placed on the Deep Neck Flexors.)
  • Aim to hold for 5 seconds.
  • Repeat 10 times.

i) Head Hover

  • Lie down on your back with your knees bent.
    • (Support your head on a pillow if required.)
  • Gently flatten your tongue to the roof of your mouth throughout the exercise.
    • This will help engage the right muscles in the neck.
  • Tuck your chin in.
  • Nod your chin downwards.
  • Whilst keeping your chin in the nodded position, lift your head off the ground.
    • Imagine you are gently squashing an apple between your lower jaw and throat throughout movement.
  • Lift as high or as low as you are comfortable.
  • Aim to feel the contraction of the muscles at the front of your neck.
  • Hold for 5-10 seconds.
  • Repeat 10 times.
  • Make sure that you DO NOT let your chin jut forward as you lift your head.

Note: If you find this exercise too difficult, support the weight of your head with your finger tips.

Address your Posture

a) Forward Head Posture

forward head posture

The Forward Head Posture is where the head pokes forwards relative to the torso.

If your head pokes forwards, this places the Deep Neck Flexors in an elongated position which is an inefficient position for the muscles function.

To optimize the function of the Deep Neck Flexor, make sure that you also address your head posture.

See post: Forward Head Posture

b) Thoracic Kyphosis

If you have a hunched upper back, this can place your head in a forward position.

See post: Hunchback Posture

Any Questions?

Feel free to leave me a comment down below if you have any questions.

a) What causes weak Deep Neck Flexors?

In my opinion: The most common cause of weak Deep Neck Flexors is having the Forward Head Posture.

When the head pokes forwards, this places the muscles at the front of the cervical spine in an elongated position.

Over time – this position can weaken the Deep Neck Flexors.

Other Causes: Whiplash Associated Disorder following a car accident. (Trauma)

b) Why should you strengthen your Deep Neck Flexors?

Weakness in the Deep Neck Flexors can lead to over activity of the Sub-Occipital and muscles at the back of the neck.

This can lead to:

  • Increase stiffness and pain in the neck/shoulder muscles
  • Headaches
  • Pain in the Base of the Skull
  • Inability to maintain proper neck and head posture
  • Limited neck movements

c) How long does it take to strengthen the Deep Neck Flexors?

It takes approximately 4-6 weeks of consistent practice to activate the Deep Neck Flexors properly.

It will also take an additional 6-12 weeks of performing the exercises to notice a significant difference in your strength.


The Deep Neck Flexors is a group of muscles consisting of the Longus Colli and Longus Capitis which are located at the front of the cervical spine.

Collectively – the main role of these muscles is to stabilize and maintain the ideal head posture.

Weakness in these Deep Neck Flexors is very common and usually occurs in conjunction with a Forward Head Posture.

Progress through the exercises to gradually strengthen your Deep Neck Flexor muscles.

5 thoughts on “Exercises for Deep Neck Flexors”

  1. Hey Mark,

    I’m curious about neck strengthening after some failed attempts with physical therapy. I’ve narrowed my mid-back pain down and found a couple movements that are helping quite a bit.

    My thoracic spine (t6-t10 very near my left scapula) lights up when I do twisting rotations, especially so on the left side if I were to pull my shoulder blades down and back.

    It’s more of an aching, constant, knot-like sensation — present at most times of the day and gets better with movement.

    Exercises that help:

    • Pec minor stretching/strengthening
    • “A” bar cable pulldowns (focusing on the top range of motion where I feel a stretch)
    • Scapula “clocks” – which immediately sends my body into the shakes

    I’ve got a sneaking suspicion that weak neck flexors may be to blame as well. When I lift my head off the ground in the dead bug position my body starts shaking uncontrollably.

    Any thoughts?

    Tried the chin tuck and lift and pretty much could feel my sternos going into overdrive.

    • Hi Andrew,

      It does sound like the deep neck flexors could be weak. The body shaking whilst you perform a dead bug could be your body trying to compensate for the lack of control and strength in the neck.

      You can definitely try the exercises mentioned on this blog post to help with that. I would suggest that you initially focus on the exercises where you do not recruit the SCM. (Keep in mind – the scm will automatically turn on with a head lift)

      In terms of the left shoulder blade pain, the 2 main things I can think of that might be causing the pain:
      1. Rhomboid issue (See post: Rhomboid muscle pain)
      2. Erector Spinae (Thoracic region) issue (See post: Mid back pain)

      Have a read of those blog posts and see if they relate to you.


    • Hi Amy,

      With the more difficult neck exercises which involve moving the weight of the head, you will naturally be engaging the superficial muscles as well. Just make sure that you are also engaging the deeper neck muscles too!
