Struggling to find a treadmill that doesn’t aggravate your knees? You’re definitely not alone in that boat, and guess what – there are some truly fantastic options out there that can help make your workouts enjoyable, and most importantly, pain-free again. Around 25% of adults over 45 in the United States experience frequent knee pain, and globally, the prevalence can range from 10% to 60%, with women being more affected than men. This shows just how widespread knee discomfort is, making the right exercise equipment crucial. The good news is, a treadmill doesn’t have to be your enemy. In fact, running on a treadmill can actually be lower impact than running on pavement because of the shock absorption in the deck.

You’re not just looking for a machine to move on. you’re searching for a partner in your fitness journey that actively supports your joint health. We’re going to walk through everything you need to know, from the must-have features to the best practices for working out with sensitive knees. Getting the right gear, like a well-cushioned treadmill and some supportive orthopedic running shoes, can make a world of difference. Sometimes, even a good knee brace for exercise can offer that extra bit of confidence. Stick with me, and we’ll help you find a treadmill that makes you actually want to get your steps in, without the unwelcome knee pain.
Why Your Knees Might Hurt on a Treadmill and How to Fix It
It’s a common misconception that treadmills are inherently bad for your knees. The truth is, often it’s how we use them, or the type of treadmill we’re using, that leads to discomfort. The repetitive motion of walking or running can put strain on the knee joints over time. But if you’re experiencing knee pain, it’s probably not the treadmill’s fault itself. It’s more likely a combination of factors, like your running posture, worn-out shoes, or even choosing a treadmill that doesn’t offer enough cushioning.
One big culprit is impact. Every step you take sends a shockwave up your leg, and if your treadmill or shoes aren’t absorbing enough of that, your knees take the brunt of it. Another issue can be poor form. Leaning too far forward, overstriding, or not keeping proper alignment can all put extra stress on your knees and hips. Also, worn-out shoes are a huge no-no. Your shoes are your first line of defense against impact, and if they’ve lost their cushioning and support, your knees will feel it.

Key Features to Look for in a Treadmill for Bad Knees
When you’re shopping for a treadmill with knee comfort in mind, you really want to pay attention to a few specific features. These aren’t just “nice-to-haves” but can be game-changers for protecting your joints.
Superior Cushioning/Shock Absorption
This is probably the most critical feature for anyone with bad knees. Think of the treadmill deck like a giant shock absorber. Good cushioning means less impact transferred to your knees, hips, and ankles. Treadmills often use different cushioning technologies, like “Cushion Flex Whisper Decks” or variable response cushioning systems, which are designed to absorb shock and add a bit of spring to your step. Some brands, like NordicTrack and Sole, are particularly known for their soft cushioning systems. The Ultimate Guide to Finding the Best Treadmill for Your Money in 2025
Look for terms like “Flex Select cushioning,” “ProShox Z cushioning,” or “three-zone variable response cushioning.” A study even found that running on a cushioned surface can reduce the load on your knees. These systems can make a significant difference, often claiming to reduce impact by a considerable percentage compared to outdoor running.
You can find a great selection of treadmills with advanced cushioning that prioritize joint protection.
Larger Running Surface
While not directly about cushioning, a bigger running surface or belt size can indirectly benefit your knees. A wider and longer deck, like 22″ x 60″, gives you more room to move naturally without feeling cramped or worried about accidentally stepping off the side. This allows for a more natural stride and can reduce the likelihood of missteps or awkward movements that might tweak a knee. If you’re taller, this becomes even more important.
Incline and Decline Options
This feature is a bit of a hidden gem for knee health. While running on a flat surface 0% incline can actually simulate a slight downhill, which can put more strain on your knees, adding a slight incline can be really beneficial. A small incline, around 1% to 3%, helps to mimic outdoor terrain, shortens your stride, and engages your posterior chain muscles glutes, hamstrings, calves more effectively. This reduces the direct impact on your knees and shifts some of the workload to stronger muscle groups. Physical therapists often recommend a slight incline for people with arthritic knees or those recovering from injury. The Ultimate Guide to the Best Treadmill for Distance Running
Some high-end treadmills even offer decline options, which can be useful for specific training, but generally, sticking to a slight incline is the safest bet for bad knees. Explore incline treadmills to find models that offer this valuable feature.
Sturdy Frame and Stability
A treadmill with a sturdy, well-built frame reduces wobble and provides a more stable platform for your workout. If the machine feels shaky, you might subconsciously tense up or alter your gait, which can put unnecessary stress on your joints. A robust frame also contributes to the longevity of the treadmill.
User Weight Capacity
Always check the treadmill’s user weight capacity. Choosing a machine that comfortably supports your weight, with a little buffer, ensures the treadmill operates optimally and maintains its cushioning properties effectively. This also contributes to the overall stability and durability of the machine. The industry standard is often around 300 pounds.
Lower Speeds and Gentle Start
If you’re just starting out or recovering from an injury, having a treadmill that allows for very low starting speeds and smooth, gradual speed adjustments is key. This lets you warm up slowly and control your pace precisely, which is much kinder to sensitive knees.
Handrails/Support
For added safety and balance, especially if your knees sometimes feel unstable, look for treadmills with sturdy, easily accessible handrails. Some models, particularly those designed for seniors or rehabilitation, even feature extended handrail systems. Treadmill Training for Cross Country Runners: Mastering the Indoor Grind
Best Treadmill Types for Bad Knees
Beyond individual features, certain types of treadmills might be inherently better suited for sensitive knees.
Cushioned Treadmills
This is the most straightforward option. These are your standard motorized treadmills but with an enhanced focus on deck cushioning. Brands like NordicTrack and Sole are often praised for their plush running surfaces. They actively work to absorb impact, making each step softer and more forgiving. If you’re looking for a traditional treadmill experience with maximum joint protection, a well-cushioned model is your go-to.
Curved Manual Treadmills
These treadmills are powered entirely by your own movement – there’s no motor. The belt is typically slatted and curved, which encourages a more natural gait and can be lower impact than some motorized options. The curved design and the fact that you’re propelling the belt yourself mean you recruit more of your posterior chain muscles glutes, hamstrings, which can actually help strengthen the muscles around your knee joint. They provide a difficult workout but with excellent shock absorption, even allowing for barefoot running. The AssaultRunner Pro Manual Treadmill is a good example of this type. While they require more effort, they can be excellent for building strength and reducing impact.
Under-Desk Treadmills for walking
If your goal is just to add more low-impact walking to your day, especially while working, an under-desk treadmill can be a fantastic solution. These are designed for walking at lower speeds and offer a very gentle impact workout. They won’t replace a full-featured running treadmill, but for consistent, light activity, they’re a great choice. The WalkingPad P1 is an example of a good walking treadmill.

What to Consider Before Buying Beyond the Treadmill Itself
Choosing the right treadmill isn’t just about the machine. it’s also about your personal circumstances and goals.
Your Specific Knee Condition
Different knee issues might benefit from slightly different approaches. If you have arthritis, for example, maximizing cushioning and gentle movements will be paramount. If you’re recovering from an injury, you might need a machine that allows for very controlled, slow speeds and excellent stability. Always consult with a doctor or physical therapist if you have a specific knee condition, as they can offer personalized recommendations.
Your Fitness Goals
Are you planning to walk, jog lightly, or do some serious running? If you’re a dedicated runner, you’ll need a more robust machine with a powerful motor e.g., 3.0 CHP or higher and extensive cushioning. For walkers, a simpler, less expensive model with good cushioning might suffice.
Budget
Let’s be real, a good treadmill can be an investment. Treadmills with superior cushioning and advanced features tend to be pricier. However, there are still excellent options across various price points. It’s about finding the best value for your specific knee health needs. Expect to pay more for machines designed to specifically accommodate knee injuries.
Space Available
Treadmills, even foldable ones, can take up a decent amount of space. Measure your workout area carefully. Many modern treadmills offer folding designs that can save space, making them ideal for home gyms. Just be mindful of how easy it is to fold and move, as some can still be quite heavy.

Assembly and Warranty
Don’t overlook the practicalities! Check reviews for how easy or difficult the treadmill is to assemble. A good warranty, especially on the frame and motor, can give you peace of peace of mind, knowing your investment is protected.
Tips for Treadmill Workouts with Bad Knees
Once you’ve got your knee-friendly treadmill, how you actually use it is just as important. Here are some pointers to keep your workouts safe and effective.
Warm-up and Cool-down
Never skip these! A proper warm-up, even just 5-10 minutes of light walking or gentle stretches, gets your blood flowing and prepares your muscles and joints for activity. Similarly, a cool-down helps your body gradually return to rest and can prevent stiffness.
Start Slow and Gradually Increase
It’s tempting to jump right into a challenging workout, but with bad knees, patience is your best friend. Start with short, low-intensity sessions. Gradually increase your speed, duration, or incline as your knees feel stronger and more comfortable. Don’t push through pain.
Focus on Form
Good posture is the foundation of pain-free running and walking. Keep your back straight, shoulders relaxed, and land your feet directly under your hips to avoid overstriding. Try to maintain a light, quick cadence – shorter, faster steps can reduce the impact on your knees by shifting the force to your lower legs.

Use Incline Wisely
As we discussed, a slight incline 1-3% can be beneficial for your knees, mimicking outdoor running and engaging your glutes and hamstrings. However, don’t overdo it with steep inclines, especially for long periods, as this can put undue strain on your knees and lower back. A zero percent incline isn’t ideal as it can simulate downhill running and increase strain.
Wear the Right Shoes
This cannot be stressed enough! Your shoes are crucial for shock absorption and support. Look for running shoes with ample cushioning, good arch support, and stability features. Brands like New Balance, Brooks, and Hoka One One are often recommended by podiatrists for knee pain relief. Replace your running shoes every 300-500 miles, or roughly every six months, as their cushioning and support wear out. You can find a wide range of best treadmill running shoes for bad knees online.
Listen to Your Body
This is probably the most important tip. Pain is your body’s way of telling you something is wrong. If you feel sharp pain, stop immediately. Don’t try to “power through” knee pain, as it can worsen your condition.
Cross-Training
Don’t rely solely on the treadmill. Incorporate other low-impact exercises like swimming, cycling, or strength training to build overall fitness and strengthen the muscles supporting your knees. Give Your Indoor Cat the Zoomies: Everything You Need to Know About Pet Treadmills for Cats!

Frequently Asked Questions
Is a treadmill good for bad knees?
Yes, a treadmill can absolutely be good for bad knees, provided you choose the right one and use it correctly. Treadmills often offer a cushioned surface that can reduce impact on your joints compared to running on hard outdoor surfaces like concrete. The controlled environment also minimizes risks like uneven terrain. However, it’s crucial to select a treadmill with good shock absorption and to pay attention to your form, footwear, and workout intensity to avoid aggravating existing knee pain.
What is the best treadmill incline for bad knees?
For bad knees, a slight incline is generally recommended. Many experts suggest setting your treadmill at a 1% to 3% incline. This range can help mimic outdoor running, reduce impact on the knees by engaging your glutes and hamstrings more, and prevent the strain that a flat 0% incline might cause by simulating a slight downhill. Avoid very steep inclines, especially for extended periods, as they can put excessive stress on your knees and lower back. What Really Makes a Treadmill “Commercial Grade”?
Can I use a treadmill with bad knees and hips?
Yes, you can often use a treadmill with bad knees and hips, but you need to be extra cautious and selective. Focus on treadmills with superior cushioning and stability to minimize joint impact. Pay close attention to your form to ensure proper alignment and avoid overstriding. Starting with gentle walking and a slight incline can be beneficial, as it engages the posterior chain muscles which support both knees and hips. Consulting with a doctor or physical therapist is highly recommended to tailor your exercise plan to your specific conditions.
What kind of exercise equipment is good for bad knees?
Beyond treadmills with good cushioning, several types of exercise equipment are generally considered knee-friendly due to their low-impact nature:
- Elliptical trainers: These provide a fluid motion that mimics running or walking without the impact, making them excellent for joints.
- Stationary bikes recumbent or upright: Cycling is a non-weight-bearing exercise that strengthens leg muscles without stressing the knees.
- Swimming or water aerobics: The buoyancy of water greatly reduces impact, making it ideal for joint pain.
- Rowing machines: These offer a full-body, low-impact workout, engaging many muscle groups while being gentle on the knees.
What are the best treadmill running shoes for bad knees?
The best treadmill running shoes for bad knees are those that offer ample cushioning, excellent arch support, and good stability. These features work together to absorb shock, maintain proper foot alignment, and reduce stress on your knee joints. Brands frequently recommended by experts and podiatrists include New Balance, Brooks, and Hoka One One. Look for models with thick midsoles and features like structured heel counters or medial support. Remember to replace your shoes regularly, typically every 300-500 miles, as their protective qualities degrade.
Is walking on a treadmill okay for bad knees?
Absolutely! Walking on a treadmill is generally considered a low-impact form of exercise and can be perfectly fine, even beneficial, for bad knees. It offers a controlled environment with a cushioned surface, which can be much gentler than walking on hard outdoor terrain.
