Best Treadmills with 400 lb Weight Capacity [2022 Reviews] 

Whether you are after fat loss, cardio efficiency or a combination of the two, a treadmill will provide the training solution you need. Yet, treadmills are heavy duty workhouses that take a beating. A lot of the cheaper machines out there do not provide you with the strength and stability to perform year in and year out. To have real confidence in you treadmil, you want it to have at least a 400 pound weight capacity. In this article, we focus in on the dozen best treadmills with a 400 lb weight capacity.

Finding a Heavy Duty Treadmill

When you are buying a heavy duty treadmill there are certain things that you need to be looking out for. You’ll need a wide running deck to accommodate larger sixed individuals. After all, a four hundred pound capacity isn’t going to do you much good if you are going to be constricted on the running belt. So, make sure that the running belt is wide enough to accommodate you natural walking gait.

If you plan on walking on the treadmill, you don’t have to worry too much about the overall length of the running belt. But if you will be running on it, you will want it to be at least 55 inches in length.

The most important feature that you need to look for is a heavy duty treadmill. The maximum user weight rating for a treadmill is the major gauge as to how sturdy it is. In order to be able to advertise a certain weight rating, the manufacturer needs to put the machine through rigorous testing. However, it is always advisable to have a minimum of a 50 pound differential between your weight and the max user weight rating. In other words, if you weigh 350 pounds, buy a treadmill that is rated to 400 pounds.

Why you need to worry about the weight rating

If you use a treadmill that is rated for a maximum bodyweight that is less than your weight, you face a number of potential problems. First and foremost among them is to do with the performance of the motor. A motor that is forced to support a person who is too heavy for it will overheat and cause mechanical damage to the workings of the motor.

If you are exercising on a treadmill that is too lightweight for you, it is quite possible that the treadmill will come to a sharp and sudden top. This can be very dangerous as it may cause the person to lunge forward uncontrollably.

Using a treadmill that is rated for less than your bodyweight will avoid the warranty. If the motor overheats, the belt rips or anything else happens you will be left out in the lurch.

The majority of heavy-duty treadmills are commercial rated to between 350 and 450 pounds. In contrast, most home use treadmills are rated between 250 and 350 pounds. 

Should you buy a folding VS non-folding treadmill?

A lot of buyers of home use treadmills prefer to invest in a folding unit due to its ability to be folded for out of sight storage. When it comes to needing a treadmill for heavy duty users, however, you are fat better off going with a non-folding option. A non folding machine will provide you with a far more stable unit. That means that a non-folding machine, even it is of the same maximum user weight rating, will always feel more solid and secure than a folding treadmill. MaxKare makes a solid folding treadmill, although it has a lower weight limit.
