Running has become one of the most popular exercises for keeping fit, and with the rise of gyms and home fitness, treadmills are increasingly common. However, many runners wonder whether using a treadmill might damage their knees. This concern isn’t unfounded, as knees are crucial joints that bear much of our weight and absorb impact during running.
In this article, we’ll analyse the pros and cons of treadmill running and its impact on joint health. Whether you’re a beginner or experienced runner, this information will help you make informed decisions about your running practice and treadmill use.
Benefits of Running on a Treadmill for Knees
- Cushioned surface: Modern treadmills offer superior shock absorption compared to many outdoor surfaces. This cushioning can reduce joint strain, including on the knees, while running.
- Pace control: Allows maintaining a steady speed, reducing the risk of overexertion. This consistency helps prevent sudden pace changes that could stress the knees.

- Controlled environment: Avoids running in adverse weather conditions that could increase injury risk. Slippery surfaces or extreme temperatures can negatively affect knees.
Potential Disadvantages for Knees
- Repetitive movement: Lack of terrain variation can overload certain areas of the knees. Outdoors, slight terrain variations distribute the load more evenly.
- Altered running technique: Some runners modify their stride on the treadmill, which could generate additional tension. This unnatural adaptation can put pressure on specific areas of the knees.
- Lack of natural incline: Flat treadmills don’t replicate the slight variations of outdoor terrain. This constant uniformity can lead to repetitive stress on the same points of the knees.
Tips to Protect Your Knees on the Treadmill
- Wear proper trainers and replace them regularly: Good running trainers provide the necessary cushioning and support to protect your knees. Replace them every 400-500 km to maintain their effectiveness.
- Maintain proper posture and running technique: Good posture and technique distribute impact evenly, reducing knee stress. Keep your back straight, shoulders relaxed, and avoid taking overly long strides.
- Alternate between treadmill and outdoor running to vary impact: Running on different surfaces helps work muscles in varied ways, avoiding repetitive overload on the same knee areas.
- Perform strengthening exercises for legs and core: Strong leg and core muscles provide better support to knees during running. Include exercises like squats, lunges, and planks in your routine.
- Gradually increase the intensity and duration of your workouts: Gradual increases allow your body to adapt and strengthen, reducing the risk of overload injuries to the knees. We recommend a 10% weekly increase.
Final Thoughts
Treadmill running isn’t necessarily bad for your knees if practised with caution. As with any form of exercise, the key lies in proper technique, appropriate equipment, and listening to your body. If you experience persistent pain, consult a healthcare professional.
Remember that proper form and gradual progression are essential for protecting your knees whilst running on a treadmill. Regular maintenance of your equipment and attention to your body’s signals will help ensure a safe and effective running experience.
