It Only Takes 5 Simple Exercises to Correct Your Posture and Sit Straighter, Says a PT

Struggling to Maintain Good Posture?

If you find it hard to keep good posture all day, you are not alone. Staying in one position for hours can leave your body feeling tired and stiff, even if that seems surprising.

A helpful way to address posture problems is to keep your spine both strong and mobile. One important area to focus on is the erector spinae muscle group in your back.

What Causes These Posture Issues?

The erector spinae is a group of three muscles:

  • Iliocostalis
  • Spinalis
  • Longissimus

Many clinicians simply call this group the erector spinae.

These muscles run along the length of the spine and help create movement across all the vertebrae. Unlike muscles that only work at one joint and perform just one or two actions, the erector spinae works more globally, helping with movement across multiple areas of the spine.

Because this muscle group plays such a major role in posture and stability, keeping it in good condition is important.

The Solution: 5 Exercises to Support Posture and Erector Spinae Strength

The following exercises can be done at least once a week and up to 4 times per week. Each one supports the spine in a slightly different way, helping improve posture, strength, or flexibility.

1. Bird Dogs

Bird dogs are especially useful for posture because they train the erector spinae, the multifidi, and other core muscles. If you are exercising on a hard surface, padding your knees can make this movement more comfortable.

How to do it

  1. Begin on your hands and knees.
  2. Keep your knees under your hips and your hands under your shoulders.
  3. Reach your right arm forward overhead while extending your left leg straight behind you.
  4. Try to create one straight line from your right fingertips to your left toes.
  5. Hold for 3 seconds.
  6. Return to the starting position.
  7. Perform 3 sets of 10 reps on each side per session.

2. Modified Swimmers

Also called modified supermans, this exercise is a good way to practice spine extension in a safer position.

If this movement causes back pain, placing pillows under your hips and stomach may help reduce the extension angle and lessen stress on the spine.

How to do it

  1. Lie face down on your stomach.
  2. Lift both hands and both feet off the floor while extending your spine.
  3. Hold for 10 seconds.
  4. Perform 3 sets of 10 reps per session.

3. Modified Good Mornings

Good mornings help strengthen the glutes, hamstrings, low back, and other muscles. This seated version offers a modified option while still targeting key postural muscles.

How to do it

  1. Sit on a firm, stable surface.
  2. Place your hands behind your head and interlock your fingers.
  3. Keep your back straight as you bend forward at the waist as far as you can.
  4. Slowly return to the starting position.
  5. Perform 3 sets of 10 reps per session.

4. Child’s Pose

Child’s pose is a classic yoga position that feels calming and meditative while also encouraging spinal range of motion.

How to do it

  1. Start on your hands and knees.
  2. Keep your knees under your hips and your hands under your shoulders.
  3. Walk your hands forward while sitting your body back until your buttocks rest on your ankles.
  4. Hold for 30 seconds.
  5. Repeat at least 4 times per session.

5. Modified Child’s Pose

If getting down to the floor is difficult, this version may be a better fit. It is similar to the modified good morning, but the goal here is flexibility rather than strength.

How to do it

  1. Sit in a firm chair.
  2. Place your hands on a table in front of you.
  3. Slowly walk your hands forward until you feel a light stretch in your back.
  4. Hold for 30 seconds.
  5. Repeat 4 times per session.

Why These Exercises Matter

The erector spinae muscle group plays an important role in posture and stability. When these muscles stay strong and mobile, they can better support the spine through daily movement and long periods of sitting.

Adding these exercises to your weekly routine may help you support your back and improve your posture over time.

Conclusion

If posture has been a challenge, focusing on the erector spinae is a smart place to start. Since this muscle group runs along the spine and helps with movement and stability, keeping it strong and flexible can make a real difference.
