5 Best Strength Training Exercises to Improve Posture

The muscles that hold you upright are detraining while you sit. Five exercises that train them again, with an animation of each one.

The muscles that support proper posture might be the most important muscles in the body. This collective set of muscles ensures we maintain proper alignment when we’re sitting, standing, exercising, and anything else we’d do in our day. The problem is the muscles that support proper posture are in a constant state of “detraining” because as a society we are sitting most of the time. Let’s explore what this detraining causes as well as some effective ways to strengthen these all-important muscles.

What is Proper Posture

For starters, let’s describe proper standing posture. The components are as follows:

  • Head and Neck Alignment: Imagine your head is being gently pulled upward by a string attached to the top of your skull. Your head is straight and your neck in line with your spine. Your head is not forward, backward, or to the side.
  • Shoulder Position: Your shoulders are relaxed and gently pulled back and down. Avoid letting them slouch forward or hunch up near your ears.
  • Back Alignment: Maintain a natural, not exaggerated, curve in your lower back. Your spine should have an “S” shape when viewed from the side.
  • Hip Placement: Align your hips directly over your feet when standing. Avoid pushing your hips forward or letting them sag backward.
  • Knee Flexibility: Keep your knees slightly bent, not locked. This helps maintain balance and reduces strain on the joints.
  • Feet and Weight Distribution: Keep your feet about hip-width apart, with your weight distributed evenly on both feet. Avoid leaning to one side or the other.

As you can see by that description, there are MANY muscles involved in proper posture. You could easily count upwards of 30 muscles involved in maintaining good posture. With so many muscles it can be difficult to know which ones to strengthen. We’ll explore that below.

Consequences of Poor Posture

Poor posture can lead to a multitude of negative health outcomes. Chronic back and neck pain are common as slouching or awkward positioning strains muscles and ligaments. This misalignment also increases the risk of injuries, particularly in areas like the back, neck, and shoulders. Sitting or standing incorrectly for extended periods can compress blood vessels, impairing circulation and causing symptoms such as swelling and numbness. Additionally, poor posture can compress the lungs, reducing their capacity to expand fully, which diminishes oxygen intake and can leave individuals feeling fatigued.

Digestive issues also arise as the gastrointestinal tract’s normal function is inhibited by abdominal compression, potentially leading to acid reflux and constipation. Joint degradation can occur over time due to the excessive pressure placed on joints in unnatural alignments, contributing to conditions like osteoarthritis. Furthermore, the tension in the neck and upper back from poor posture can lead to frequent tension headaches.

Muscles and ligaments

Slouching holds the tissues that support your spine in a lengthened, loaded position for hours. The strain shows up as aching in the neck, upper back and lower back.

2

Breathing

A collapsed chest leaves the lungs less room to expand. Each breath moves less air, and less oxygen over a long day is one reason slouching feels tiring.

3

Digestion

Folding forward compresses the abdomen and presses on the stomach. That pressure can push stomach acid the wrong direction and slow how fast food moves through the gut.

4

Joints

A joint held off its normal line wears surfaces that were never built to carry that force, and years of that wear contribute to osteoarthritis.

Beyond physical health, posture also influences appearance and mental health. A slumped or slouched appearance can negatively impact first impressions and portray a lack of confidence, which might influence social and professional interactions. There’s also a noted link between poor posture and increased feelings of depression and stress, possibly due to discomfort and a decrease in self-esteem. Addressing posture not only helps alleviate physical ailments but also enhances overall well-being and energy levels.

When the ache concentrates in one shoulder and shows up when you reach overhead, the problem may have moved past posture alone. Mike walks through that specific pattern in Shoulder Impingement: Identifying and Alleviating.

Best Exercises to Improve Posture

All is not lost in terms of improving posture, even if you sit a lot. Below are five great exercises you can perform to strengthen those important posture muscles. Each one includes an animation of the movement so you can see what the exercise should look like before you try it.

Exercise 1 to Improve Posture: Squats

Even when done with just your body weight, squats are one of the best postural exercises when you perform them correctly. The exercise engages muscles in your shoulder blades, core, and hips that all contribute to better posture.

Primary muscles workingSupporting muscles working
Set up
Feet about hip to shoulder width apart, toes turned out slightly. Put your weight in the middle of each foot, not on your toes.
The movement
Push your hips back first, then bend your knees. Keep your chest facing forward rather than down at the floor. Go as low as you can while your lower back holds its natural curve.
You should feel
Work in your glutes and the front of your thighs, and a steady brace through your midsection. Your upper back stays flat instead of rounding.
Start with
2 sets of 8 to 12 reps, body weight only. Hold a counter or a doorframe if you need the balance.

Exercise 2 to Improve Posture: Planks

Planks activate the deep abdominal muscles in the front of our torso. These muscles act as a corset around the torso to maintain spinal stability and posture when activated. Given the amount of time we sit, these muscles get weaker. A little planking goes a long way.

Primary muscles workingSupporting muscles working
Set up
Elbows directly under your shoulders, forearms flat on the floor, feet about hip width apart.
The movement
Push the floor away with your forearms, squeeze your glutes, and hold one straight line from your ears through your hips to your heels. Keep breathing.
You should feel
A deep brace across the front of your abdomen. If you feel the effort in your lower back instead, your hips have dropped below the line.
Start with
3 holds of 20 to 30 seconds. Drop to your knees and keep the same straight line if 20 seconds is too long.

Exercise 3 to Improve Posture: Side Planks

Side planks activate the deep abdominal muscles on the side of our torso. Again, these muscles act as a corset around the torso to maintain spinal stability and posture when activated (except here on the sides, instead of in the front). As a bonus, side planks also activate muscles in the lateral hip, which is key to the alignment of your pelvis.

Primary muscles workingSupporting muscles working
Set up
Lie on one side with your elbow under your shoulder and your feet stacked, one on top of the other.
The movement
Lift your hip off the floor until your shoulder, hip and ankle line up. Hold, then lower with control instead of dropping.
You should feel
Work down the side of your torso and in the outside of your bottom hip.
Start with
2 holds of 15 to 20 seconds per side. Bending your knees and resting on them shortens the lever and makes the hold easier.

Exercise 4 to Improve Posture: Shoulder Blade Squeezes

The ability to have strong muscles to pull the shoulder blades back and down is critical to good posture. Simply doing the exercise of squeezing your shoulder blades back and down and holding for a few seconds, for sets of 10, can have a huge impact on muscles that are responsible for keeping the upper part of your spine in the right position.

Primary muscles workingSupporting muscles working
Set up
Sit or stand tall with your arms relaxed at your sides. This one works at a desk, which is the point.
The movement
Draw both shoulder blades toward each other and down toward your back pockets. Hold 3 to 5 seconds, then let go completely before the next rep.
You should feel
Work between your shoulder blades and just below them. Your shoulders should not ride up toward your ears.
Start with
2 sets of 10, holding each rep 3 to 5 seconds. Several short sets spread across the day beat one long set.

Exercise 5 to Improve Posture: Supermans

We saved the best for last. This exercise activates nearly every extensor muscle on the backside of your body. We spend so much time leaning (or hunching) forward during our day, so getting all of these muscles activated at once is a high mileage way to improve your posture.

Primary muscles workingSupporting muscles working
Set up
Lie face down with your arms reaching past your head and your legs straight.
The movement
Lift your hands, your chest and your legs off the floor at the same time. Keep your eyes on the floor so your neck stays in line with the rest of your spine.
You should feel
Work along both sides of your spine, in your glutes, and in the back of your thighs.
Start with
2 sets of 8 reps, holding each rep about 2 seconds at the top. Lift only the arms, or only the legs, if lifting both bothers your lower back.

Where to Start, and How Often

Posture is not something you fix once and then keep for good. The muscles that hold you upright respond to what you ask of them, and right now most of us are asking them to do almost nothing for eight or nine hours a day.

You do not need all five exercises on day one. Start with the shoulder blade squeeze and one of the two planks, four or five days a week. The squeeze takes about a minute and you can do it in your chair without anyone noticing. Add the squat and the Superman once those first two are a habit.

The muscles that got weak from sitting will get strong again the same way they got weak, a little at a time. Give these exercises six weeks before you decide whether they are working, and pay attention to how your neck and upper back feel at 4pm rather than to what you see in the mirror.

If you would rather be coached through these movements than guess at them on your own, our group strength training classes run these same patterns with an exercise physiologist watching and correcting. And for women past 50, the shoulder blade squeeze and the Superman train back-side muscles that also help slow bone loss, which Mike covers in the five most important benefits of strength training for women.

Not Every Back Needs the Same Five Exercises

Our exercise physiologists assess how you move, then build a strength plan with you that fits your schedule and your goals. The MY180 program pairs you with a Health Coach, a Registered Dietitian, and an Exercise Physiologist working from one plan for 180 days.
