Buying a higher capacity treadmill (like 350 lb) is always beneficial for getting a stable and smooth training experience in the long run.

But are you sure that a 350 lb capacity treadmill is sufficient for you, or do you need a higher one?

Note: If your body weight is 300 lb or less, a 350 lb weight capacity treadmill can serve you very well. But if your body weight is more than that, you should look for a higher capacity treadmill.

The thumb rule is that buying a treadmill with 50 pounds higher weight capacity than your body weight helps maximize your machine’s stability and durability for the long years.

So, is a 350 lb capacity treadmill sufficient for you? Let’s check out the best treadmill 350 lb capacity, picked from different categories, so you can always choose the best one according to your needs.

Things to Consider When Buying a 350 lb Capacity Treadmill

Here’re the things you should check out when choosing a 350 lb capacity treadmill.

Weight Capacity

The first and most obvious thing we’ll check is the weight capacity, especially when buying a treadmill for heavy users.

Although the manufacturer’s recommended weight capacity is 350 lb, we shouldn’t go with it if our body weight is 350 lb or closer.

The reason is that buying a treadmill with matched/closer weight limit will most likely gonna be shake and unsmooth while you run. And it can also decrease your machine’s durability.

So, it’s always better (and recommended) to go with a 50 pounds higher capacity treadmill than its user.

For example, if your body weight is 300 pounds or less, then a 350 pounds capacity treadmill can efficiently carry you. But if you’re a 350 pounds person, going with a 400 pounds capacity treadmill or higher is wiser.

Performance

When it comes to performance, getting a powerful motor is crucial, especially when a heavy person is using it.

A high-performance motor can smoothly run at its top speed while carrying a heavy person.

Here’s the general recommendation for motor power:

  • Walkers over 250 lb: 2.5 HP or above
  • Walkers over 300 lb: 3.0 HP or above
  • Power joggers/runners over 250 lb: 3.5 HP or above
  • Runners over 300 lb: 4.0 HP or above

You can choose the speed according to your training style. Joggers and runners may need a 10 mph to 12 mph speed, while a lower speed treadmill may be sufficient for walkers.

Comfort

To get optimal comfort while on the treadmill, you should at least have a decent size deck to walk or run comfortably without slipping or hitting your elbows on the machine.

The general recommendation for belt size is:

  • For walking: 16″ x 50″
  • For jogging: 20″ x 55″
  • For running: 20″ x 60″

However, you can increase or decrease your deck size according to your height and running style.

If you’re a senior or lack balance, you can look for a treadmill with extended handrails to get support during exercise.

Farther more, if you’re interested in higher-end treadmills, you may get a fan that can keep you cool during a long intensive session.

Stability and Durability

Stability and durability are also important to check out, especially when you’re buying a running machine.

You should ensure that the treadmill is equipped with a heavy-duty frame that can carry a heavy person efficiently without shaking and breaking.

Pro Tip: Check out the treadmill’s weight capacity and warranty, which are significant clues of a treadmill’s built-in quality and durability. The more your treadmill offer, the better.

Warranty

How extended warranty life you’ll get depends on your budget and the brand you’re going with.

You may find brands (like XTERRA) that give you a lifetime warranty, whereas some may offer 10-15 years, which is a standard range you can expect from higher-end models.

Here’re the best treadmill warranties:

  • Frame and motor: At least 10 years to lifetime coverage
  • Parts and Electronics: At least 2 to 3 years
  • Labor: 1 to 2 years

However, in lower-end models, you may get a short warranty life which is acceptable/reasonable according to their price.
