Why CHP Trumps Every Other Feature

The most crucial factor to consider when evaluating a treadmill’s performance is its motor’s continuous horsepower (CHP). You should particularly look closer into the CHP of a model if you desire a 400 lb capacity treadmill. Here is why:

Measuring Treadmill Motor-Strength

CHP is a reliable measurement of a treadmill motor’s true power, as it indicates the ability to maintain consistent performance during prolonged periods of use.

A higher CHP rating translates to a more powerful and durable motor, essential for users who plan to use the treadmill for extended sessions or high-intensity workouts. If you are interested in treadmill motors, you can find out more here.

Importance of CHP in Treadmills with 400 lb Weight Capacity

The importance of a treadmill’s CHP cannot be overstated, as it directly impacts the overall performance and longevity of the machine.

A motor with a higher CHP rating will provide a smoother and more stable running experience, even at higher speeds and inclines.

This is particularly important for heavier users or those who engage in rigorous training, as a more powerful motor is better equipped to handle the increased demands on the treadmill.

Energy Efficiency

Additionally, a treadmill with a higher CHP motor is generally more energy-efficient, as it can operate at lower speeds without straining or overheating.

This helps reduce energy consumption and extends the motor’s life, making the treadmill a more cost-effective investment in the long run.

How Many CHP are needed for a Treadmill with 400 lb capacity?

Every 400 lb capacity treadmill in this article has enough CHP for heavy users, but many cheaper options on the internet have a very low CHP compared to the weight capacity they claim to have. Others try to confuse the customer by writing about the maximum horsepower, which is usually way higher but doesn’t say much about the treadmill’s usability. Be aware of such dirty tricks!

If you’re searching for a treadmill with 400 lb capacity, you should aim for at least 3.25 CHP to ensure a smooth workout.

My Experience With 400 lb Capacity Treadmills


When I first considered buying a treadmill a few years ago, I knew absolutely nothing about the subject. All the specs, weight capacity, weight, maximum power, continuous power, and all the different brands told me very little. Like many people, I then made the mistake of buying a cheap treadmill secondhand and from an unknown brand.

Not being too heavy myself, I didn’t worry about the weight capacity of 200 lb. What a mistake! Because a sufficient capacity doesn’t necessarily mean that the machine can be loaded with the amount stated. If you load the machine with 340 lb at a capacity of 350 lb, it will certainly withstand that at first. But that doesn’t mean it will survive for 2 hours!

After jogging on my treadmill a few times, and my level gradually increased, I once decided to train on it for two full hours at a stretch. After 100 minutes, the motor suddenly started to spark and smoke, and the entire basement was filled with a nasty smell.

I had overused the electric motor, and inside, the insulation of the motor winding began to melt. Since the motor is the heart of any treadmill and not worth replacing, I had to throw the entire machine away.

After that, I studied treadmills intensively for weeks and talked to numerous experts. In the end, I decided on a 400 lb capacity treadmill despite my rather light body weight.

Even if you don’t weigh 400 lb, a 400 lb capacity treadmill is a good choice because the added horsepower of the machine serves its longevity and continuous performance.
