What To Know Before Buying a Heavy-Duty Treadmill

A heavy-duty treadmill needs to have the capacity to take the impact of the person running or walking on it. It needs to be able to deal with whatever is thrown at it, while still having the features you associate with a regular treadmill. This is a weight-loss journey, and you need, nay expect, a treadmill which can make the journey with you.

Let’s take a closer look.

Treadmill Weight Capacity

If you have ever been to a gym, then you have probably jumped onto a treadmill without thinking about it (and, when we say ‘jumped on,’ we mean carefully stepped on). Most gyms opt for treadmills which can accommodate anyone, so there is never any reason to check the weight capacity of the machine.

When it comes to purchasing a treadmill, the capacity is vital. This should be the first thing that you check. Make sure that you know your own weight, and then buy a treadmill based on that. If it cannot hold you, do not buy it. We would also recommend buying one which is rated for at least 20% more than you weigh, even though there are variances already taken into account.

A reliable and sturdy treadmill will feel better when you are walking and running and will last longer too.

Construction Quality And Durability

How long do you want your treadmill to last? Forever, I hear you say. Well, you had better buy one which is well constructed and durable. A treadmill for heavy persons will take more strain than one used by a lighter person (which you will eventually be), so you need to make sure that it can take this strain.

The weight capacity of the machine will give you an indication of the construction quality, with a higher-capacity machine being more robust, but there are other indicators. A treadmill which comes with an extended warranty means that the manufacturer has confidence in their treadmills and that should indicate that the machine is well-built.

Motor Size

The more power that you have in the motor, the longer the motor will last, and the more speed you will get from it (generally speaking).

You will find that most treadmills come installed with two motors; one will control the speed of the belt, and the other will control the incline. The motor is one of the most critical parts in a treadmill, so you need to make sure that you are investing in quality.

You want a motor which is rated at 2-3 horsepower. This will be fine for light workouts but will also handle tougher workouts too. When you are starting, most motors will be fine, but you want to invest in one which will work as your fitness improves and you are going harder and harder.

Running Surface Area

Once you have a powerful motor, you need an excellent surface for you to run on. You want a treadmill for home use to be fun and enjoyable, and the running surface plays a large part in that.

The surface area depends a lot on your height and stride. If you are taller, then you want to go for a larger running area. A large deck means a more significant treadmill, so you also need to think of your space. We recommend going as big as you can. A larger area is a lot more fun to run on than one where you are restricted.

Technology

You have your motor and running area, but what technology is bringing everything together? You want to think about the functions and the features which you want, against the functions and features of the machine. You should also be thinking about the user interface, and the way the functionality of the treadmill is presented. There are going to be times when you are running and need to use the controls, so they should be straightforward and intuitive but powerful at the same time.

Along with basic functionality, most treadmills also have Bluetooth and Wi-Fi connections, USB ports, heart-rate monitors, and safety features. If you are worried about not being able to stop the treadmill, then look for an emergency stop button or a connector which will stop the machine if you fall or slip.

Incline Options

Having an incline can be beneficial if you want to start out with walking, or if you want to add some challenge to your runs. The one thing which you need to look at when you are deciding on your treadmill is how much incline you want. The more incline you have, the more flexibility you have for your workout at home.

Most treadmills can go up to a 20% incline, and this will be sufficient for almost all users. However, not all incline is created equally. We recommend looking for a machine which has automatic incline versus a manual incline.

An automatic incline will allow you to change the incline as you run, while a manual incline may need you to stop running to change the incline.

Tread Belt Cushioning

If you are running for weight loss, then your knees and ankles may be taking a lot of stress and strain. When you are outside, you can run on soft surfaces like grass. When you are inside, you need the treadmill to have a cushioning system.

A cushioning system will reduce the impact on your joints and muscles. This means less fatigue and longer workout sessions. It also means fewer injuries. The heavier you are, the more cushioning you want in the treadmill.

Foldable or Non-Foldable Design

An often overlooked factor when buying a treadmill is where it is going to go. The amount of space will determine if you need a compact treadmill, one which folds, or you can accommodate any size. If you can have the platform down all of the time, then you do not need to worry about any space issues.

If you have space issues, then a folding treadmill is the perfect addition to your home. With a folding treadmill, the running platform folds up, and there are some which are on wheels and can be moved into storage when not in use.

Your Budget

With every significant purchase, there is going to be money involved, so you should always start with a budget. There are two things to remember here.

  • You should never forget that you get what you pay for, so ensure that you budget enough to pay for a treadmill which will last.
  • You should also stick to tour budget once you have set it, and do not be afraid to buy nearer the top end of your budget.

Cheap treadmills can go for as little as $200, but they are not going to last, and they may not even be able to accommodate your weight. For $1,000 you can get a quality treadmill which will last and save you money in the long run.
