What to look for when buying a Heavy-duty Treadmill: Buying Guide

Here’s everything you need to keep in mind while buying a treadmill for heavy persons: 

Weight Capacity 

Looking at the weight capacity while buying a treadmill for a heavy person is crucial. They should be strong enough to accommodate a few pounds more than the weight of their heaviest user. 

This is important for two reasons. The first is that it prevents premature wear-and-tear of the treadmill in the form of noises, loosening of parts and wearing down of the belt. Second, a higher weight capacity means the frame is sturdier and can withstand the most challenging workout sessions without wobbling.


The motor’s power directly impacts the effectiveness of your workout. Continuous Horsepower (CHP) is a critical metric since it indicates a treadmill’s power. That said, given below is a list of the minimum CHP requirements for a treadmill: 

  • For Walking – at least 2.0 CHP
  • For Jogging – 2.5 CHP or higher
  • For Running – 3.0 CHP or higher

We suggest you opt for a higher-capacity motor, especially if you are on the heavier side of the weighing scale.

Running deck area 

The running deck area should have sufficient space to suit your needs. A wider belt can provide a spacious and more comfortable training experience for a heavy person. Choose machines with belts at least 20 inches wide and 60 inches long. 

Bear in mind that if your tread belt length is shorter than 60 inches, you will not be able to run on it. However, it will be fine for walking or light jogging. 

Tread belt cushioning 

Tread belt cushioning is essential for heavy users because it absorbs shock and reduces the impact on your joints, particularly the knees and ankles. If the treadmill deck is too hard or rigid, it can cause discomfort or injury.

We suggest you get a treadmill which offers good cushioning for long-term use. 


An incline essentially simulates walking or running uphill or downhill, depending on the angle you set. Though a zero-incline treadmill can improve cardiovascular stamina and tone your muscles, an incline helps you achieve it in a relatively lesser time frame.  

If you prefer a wider range of challenging workouts, and if your budget fits, consider buying a treadmill with incline/decline.


Your final consideration as a buyer is the product warranty. Since most treadmills become a huge part of your life, looking for a model with an excellent warranty makes sense. Go for a machine that preferably offers long-term coverage, especially for the frame.

Tips to Maintain the Treadmill

It is important to carry out regular maintenance on your treadmill if you want it to last longer. Here are a few ways to do so: 

Lubricate the belt

Too much friction can cause the belt to malfunction. To avoid this, you must lubricate the deck under the belt regularly. While many treadmills can be maintained using standard-issue lubricants, some may require specialized waxes or sprays. Always check the user manual before you perform this activity. 

It is also important to remember never to apply any lubricant on top of the running belt because this could make it slippery and compromise your training experience.

Check alignment and tension on the belt 

It is important for both, performance and safety, to ensure the belt on your treadmill is aligned and has the correct tension. 

Examine the belt for signs of misalignment, if any. The belt must be centered on the treadmill deck without rubbing against the sides. If the belt is misaligned, adjust the bolts at the rear end of the treadmill until it falls in place. 

Replace the belt when needed

If you notice tears or discoloration on your treadmill’s belt, it’s time to replace it. To do this, start by powering off and unplugging the treadmill. Then, remove the end caps and loosen the bolts holding the roller in place. 

Slide the old belt off the treadmill before replacing it with the new one, ensuring it’s centered and tensioned correctly. Re-attach the roller and end caps before you test the new belt by walking on the treadmill slowly. 


If you are a heavy-weighted user, selecting a treadmill that can sustain your weight and maintain joint health is extremely important.

Our top pick for a heavy person treadmill would be the Bowflex T10, owing to its robust build quality and fantastic user experience. Its powerful motor and spacious, shock-absorbing running deck offer comfortable workouts. Also, advanced features like integration with streaming apps and Bluetooth connectivity make it a highly functional and convenient fitness equipment.


Is running bad for your knees if you’re overweight?

Your knees take up most of the onus of your weight while in the vertical position. This can be exacerbated by high-impact activities such as running. However, moderate-speed running is beneficial for the knees, even if you are overweight. It helps to strengthen the muscles around the knees, making them more resilient. 

Running can also be an effective way to lose weight and improve overall health if done safely and gradually. 

If you are looking for a low impact workout for your knees and back, you can check out the best Elliptical Rowing Machines or Elliptical Stepper Combo.

How long should an obese person workout on the treadmill?

Though there is no “one size fits all” protocol, the key is to stay active consistently to see the best results. 

Start by walking on your treadmill for at least 15 minutes each day. Increase this after a couple of weeks as you feel more comfortable. Target to reach a steady walking pace for 45 mins. This will help you burn enough calories and progress along your fitness journey. 

If you are low on space, consider getting a treadmill that fits under your bed so you can hit your daily activity goals.

Are Treadmills Better Than Walking Outdoors?

Both treadmills and walking outdoors offer a range of benefits. Choosing between the two ultimately depends on individual preferences and circumstances. 

Treadmills are a very convenient way of pursuing fitness since they are not dependent on weather conditions or time of day. Also, compared to walking outdoors, treadmills are softer on the joints and can be controlled. On the other hand, walking outdoors promotes exposure to fresh air and sunlight, which has many of its own health benefits. 

Can You Use a Treadmill if You Are Over The Weight Limit?

Using a treadmill is not recommended if you exceed the weight limit specified by the manufacturer. Exceeding the weight limit can damage the machine and increase the risk of injury to the user. 

What Extra Features of a Treadmill Will Help Me Lose Weight?

Here are some extra treadmill features that can help with weight loss:

  1. Incline options
  2. Wider speed range 
  3. Preset workout programs
  4. Integration with fitness apps 

However, remember that weight loss happens with a disciplined combination of exercise, a healthy diet and a wellness-aligned lifestyle.
