If you spend most of your day sitting at a desk, working from home, driving, studying, or watching television, you may have experienced lower back pain, stiffness or tightness. You may even notice that your back feels fine in the morning but becomes increasingly uncomfortable as the day goes on.
So, why does sitting for long periods contribute to back pain? The answer isn’t simply that “sitting is bad.” Rather, prolonged sitting reduces movement and keeps your body in the same position for extended periods. Over time, this can contribute to stiffness, muscle weakness, reduced mobility and increased sensitivity to discomfort.
The good news is that movement and appropriately prescribed exercise can help. This is where Biokinetics can play an important role. At Reignite Health, Bokamoso Mthimkulu Biokineticist uses personalised exercise therapy to help clients manage back pain, improve strength and mobility, and return to the activities they enjoy.
Why Does Sitting Cause Back Pain?
Your body is designed to move. But sitting itself isn’t necessarily harmful. The problem is often sitting for too long without changing position or moving.
When you sit for several hours, you may experience:
- Reduced movement through the spine
- Hip stiffness
- Reduced muscle activity
- Muscle fatigue
- Increased sensitivity to discomfort
- Reduced circulation
- Poor movement habits
- Reduced overall physical activity
The longer you remain in one position, the more likely you are to feel stiff and uncomfortable.
1. Your Muscles Become Less Active
When you’re sitting, many of the muscles responsible for supporting and moving your body aren’t working as much as they would when you’re standing, walking or exercising.
Over time, consistently low levels of activity can contribute to reduced strength and physical conditioning. This can make everyday activities more demanding. A Biokineticist can assess your strength and identify areas that may benefit from targeted exercise.
2. Your Hips Can Become Stiff
Sitting keeps your hips in a flexed position. If you’re sitting for hours every day, you’re spending a large amount of time with your hips in the same position.
This doesn’t mean that sitting automatically “shortens” your hip muscles, but prolonged inactivity can contribute to reduced hip mobility and tolerance to movement. Limited hip mobility may also influence how you move through your pelvis and lower back. Mobility and strengthening exercises can help restore your ability to move comfortably.
3. You May Start Slouching
After several hours at a desk, it’s natural to change position.
You may begin:
- Slouching
- Leaning to one side
- Sitting with your shoulders rounded
- Sliding forward in your chair
- Propping your head on your hand
There is no single perfect sitting posture that you need to maintain all day. In fact, constantly trying to hold a rigid “perfect posture” can become uncomfortable. A better strategy is to change positions regularly and move throughout the day.
4. Your Back May Become Less Tolerant of Movement
When your body becomes accustomed to sitting for long periods, activities that require more movement can feel harder.
For example: You sit for eight hours then you suddenly go for a long walk, or you spend Saturday gardening or cleaning the entire house. Your body may not be conditioned for that sudden increase in activity.
A Biokineticist helps you gradually build your physical capacity to be able to do daily tasks with ease.
5. Sitting Often Goes Together with an Inactive Lifestyle
The problem may not be the chair itself. It may be the total amount of movement you’re getting during the day.
Someone who sits for eight hours but regularly walks, exercises and takes movement breaks has a very different activity pattern from someone who sits for eight hours and then spends the evening on the couch. Your overall daily movement matters.
How Can Biokinetics Help with Back Pain?
Biokinetics uses exercise therapy to improve physical function. For someone experiencing back pain associated with prolonged sitting, a Biokineticist may assess:
- Spinal mobility
- Hip mobility
- Core and trunk strength
- Lower-body strength
- Posture and movement patterns
- Balance
- Functional movement
- Cardiovascular fitness
- Exercise tolerance
Your programme can then be designed around your specific needs.
6 Ways Biokinetics Can Help with Sitting-Related Back Pain
1. Strengthening Your Core and Trunk
Your trunk provides a foundation for many everyday movements. A Biokineticist can prescribe progressive exercises to improve strength and control around the abdominals, back muscles, pelvis and hips.
2. Improving Hip and Spinal Mobility
If you spend much of your day sitting, mobility exercises can help you move your hips and spine through a greater range of comfortable movement. Your programme may include appropriately selected:
- Hip mobility exercises
- Spinal mobility exercises
- Stretching
- Active range-of-motion exercises
3. Improving Overall Strength
Back pain doesn’t exist in isolation. Your legs, hips and trunk all contribute to how you move. Progressive strengthening can improve your ability to perform everyday activities such as walking, climbing stairs, bending, lifting, and getting out of a chair.
4. Improving Your Exercise Tolerance
If you spend most of your day sitting, exercise may initially feel difficult. A Biokineticist can help you gradually build your capacity. Your programme can start at a level your body can tolerate and progress gradually.
5. Teaching You How to Move More During the Day
Your Biokinetics session isn’t the only opportunity to move. Your Biokineticist can help you develop strategies such as:
- Taking regular movement breaks
- Walking during phone calls
- Standing periodically
- Changing sitting positions
- Using stairs where appropriate
- Adding short walks throughout the day
6. Helping You Return to Activities You Enjoy
This might mean being able to walk without discomfort, exercise at the gym, travel, garden, play with your children, play sport, work comfortably, or enjoy weekends without worrying about your back. The goal for Biokinetics is to help you get through your day with minimal discomfort and pain.
How Often Should You Move When Sitting?
Taking breaks may differ per person or the deadline you are working on. This means that a break could be every 30 minutes, or 90 minutes. The aim is for you to consciously take a break. For example, you could:
Sit → Move → Sit → Move → Sit → Move
Your movement break could be as simple as:
- Standing up
- Walking around the office
- Getting a glass of water
- Doing a few gentle movements
- Walking to speak to someone instead of sending a message
The important thing is to avoid spending the entire day in one position.
What About Your Desk Setup?
Your workstation can also influence your comfort.
Consider:
- Is your chair comfortable?
- Is your screen at an appropriate height?
- Are your feet supported?
- Are you able to change position?
- Are you working from a laptop for hours without adjusting your setup?
Is Sitting Always the Cause of Back Pain?
No. Back pain is multifactorial. Factors that may contribute include:
- Physical inactivity
- Muscle weakness
- Previous injuries
- Stress
- Poor sleep
- Work demands
- Sudden increases in activity
- Repetitive movements
- Psychological factors
- Other medical conditions
A proper assessment with a Biokineticist can help identify the factors contributing to your symptoms.
When Should You See a Healthcare Professional?
Most episodes of uncomplicated back pain aren’t caused by a serious condition. However, seek medical assessment if you experience back pain alongside concerning symptoms such as:
- Significant or progressive weakness
- Loss of bladder or bowel control
- Numbness around the groin or saddle region
- Severe pain following significant trauma
- Fever or feeling systemically unwell
- Unexplained significant weight loss
- Severe or worsening symptoms
A Biokineticist can also refer you to the appropriate healthcare professional if your presentation requires further medical investigation.

Final Thoughts
Sitting all day doesn’t automatically mean you’re going to develop back pain. The bigger issue is often too much time in one position and not enough movement throughout the day. Your body needs regular movement, strength and physical conditioning.
If you’re spending most of your day sitting, start small. Stand up, walk around, change position, move your hips, strengthen your body, and take regular breaks.
And if you’re already experiencing persistent back pain, don’t feel that you simply have to “live with it.” A Biokineticist in Fourways can assess your physical function and develop a personalised exercise programme to help you move better and build your physical capacity.
Bokamoso Mthimkulu Biokineticist at Reignite Health can help you take that first step.
