What are the benefits of decline on a treadmill?

Training on a decline treadmill has various benefits, such as:

Strengthens the quads

Quads help to maintain balance and control your movements. Training on a decline treadmill simulates downhill running that activates the muscles in your quads. With constant workouts on a decline treadmill, you can strengthen your quads and achieve strong legs.  

Makes the knees stronger

The knees need to work harder while running on a decline as compared to running on a flat surface. With consistent training on a treadmill with decline, the muscles, tendons, and ligaments around the knee get stronger, and stability of the knee joint improves.  

Variety in workout

Running on a flat treadmill may get boring, and your body might not feel the stress and challenge it needs for toning muscles. With an incline and decline treadmill, you can enjoy a variety of workouts and keep your sweat sessions interesting. 

‘Break’ in the middle of an intense workout

The decline settings on your treadmill will give you a ‘break’ during an intense workout session. When you’re running or walking downhill, your body requires to put in less effort than climbing uphill or running on a flat surface. So, with a decline treadmill, you can catch your breath before continuing your workout.

What are the disadvantages of decline on a treadmill?

You need to keep in mind the following when using a treadmill with decline: 

Burns fewer calories

While running downhill may improve the strength of your quads and knees, it will burn fewer calories. As we discussed, running downhill requires lesser effort and doesn’t challenge the body enough to burn a lot of calories. 

However, to maximize your workout session and total calories burnt, you can take a stim-free pre-workout supplement

Risk of injury 

If you’re not used to downhill running or switch the motion too fast, it will put additional stress on your knees and joints. This may become a cause of muscle strain and even injuries. To avoid this, start in a gradual manner and ensure you wear proper footwear suited for workouts. 

Tips on how to train on a Decline Treadmill

Here are some useful tips on how you can train on a decline:

Start slow and let the muscles get used to the movement

When you start training on a decline treadmill, start with a low incline and on a slow speed. Increase it gradually with time. Let your muscles get used to the movement. 

Lean forward

Lean your body slightly forward to control your speed and maintain balance and posture. 

Lengthen the stride

When in the decline position, you need to lengthen your stride to control your descent and maintain momentum. 

Relax, but focus on posture

Downhill movement can often be relaxing, but make sure to maintain a good posture. This will ensure you avoid injuries and boost your performance. 

Avoid decline if you have an injury

Users who have joint or other injuries should avoid using the decline to prevent aggravation of pain. 

Buying guide: What to look for when buying an Incline and Decline Treadmill?

Here’s what you need to keep in mind when buying a decline treadmill:

Range of decline and incline

When you’re buying an incline and decline treadmill, look for an option that has a good incline-decline range. The ideal decline slope is -3%, which may go up to -6% and even -10%. When you have a good range of incline and decline levels, you can enjoy a variety of workouts and target different muscle groups. 

If you live in a low-ceiling apartment and want to use the incline and decline features, consider investing in a low-profile treadmill

Ease of decline adjustment

While a good incline-decline range is beneficial, it is also important to be able to transition smoothly between levels.

To avoid interruptions in your workout and even injuries during the sessions, look for machines that offer quick and easy slope adjustments. Switching between incline, decline, and flat running shouldn’t be a hassle. 

Cushioning mechanism

The prime reason legs feel sore and hurt after a run on natural terrain is the unevenness and lack of bounce. So when you are purchasing a treadmill, look for good cushioning technology under the running belt. This will prevent impact on your joints and minimize injuries and soreness, giving you a safe and comfortable running experience.  


Budget is largely a personal decision and decline treadmills are available in a wide price range. 

Set a budget and look for options within that range. The usual trend is that treadmills costing less would have a more basic set-up, while high-end treadmills are loaded with premium features.


The warranty coverage of a treadmill gives you a very good idea about how much support you will receive if anything goes wrong with it. It also indirectly lets you know how much confidence the manufacturers have in their product.

Invest in a machine that has a wide warranty net that includes frame, components, electronics and labor.
