Fitness Equipment

All of us know that exercising is a part of a healthy lifestyle and it is needed to stay fit as well as preventing various health issues that many of us are suffering as a result of modern living habits which prominently rely on convenience. Deciding to cook your own food and choosing natural ingredients with as less processed food as possible is another way to achieve better health but, not all of us are able to put the effort due to various circumstances.

Many of us prefer to use the gym because they are convenient and you can choose any exercise equipment to use or focus on. We can also exercise in groups to get more motivated and more controlled especially those with certain goals such as body toning or weight loss. On the other hand, some people prefer the other way, spending the time outdoors and getting their physical activities while enjoying the surroundings such as cycling or running which is more fun for we can get fresh air while sweating.

For the rest of us, leaving the house and the idea of spending the time at a gym sounds uninteresting or not convenient for the type of lifestyle we are doing. We personally prefer to exercise alone and choose the time freely which makes outdoor and gym are not ideal. If this sounds like what you are struggling with as well, we can get enough physical activities at home without having to step outside. There are various exercises such as aerobic or yoga that we can do at home just by following a video.

They are also convenient for in most cases we don’t need anything besides a comfortable clothing but, if you are a fan of cardio and love running, having a tool or machine will be the best idea. There are various fitness equipment and tools that we can purchase to be used at home and what’s great is you can access them anytime you have spare minutes to workout. The options however, are different for many people and it is always great to pick the one we like better.

Exercise is always good compared to no exercise at all but your ideal equipment is based on your own preference since it will have a higher chance to be used in the prolonged time. For example, those who want to build muscle or prefer weight training will opt for dumbbells or barbells and those who love cardio or move their body a lot will probably be better with equipment like rowing machines and treadmills. Instead of what’s popular, it is better to go for something we are sure will be using.

About  Proform 400i and 600i

Talking about cardio fitness equipment, one of the most popular choices is a treadmill and this is not without a reason because they are probably the easiest to use. Almost all of us with no leg injury or inconvenience can walk or run at a certain speed which makes the machine versatile for users to utilize and it also exercises various body parts depending on our technique. The best benefit is we don’t have to worry about the weather or temperature anymore to run.

As a common fitness equipment, treadmills are offered by lots of manufacturers in the market and those who produce fitness machines will most likely have a treadmill in the collection but there are many that are focusing on this type of equipment alone. Among those many options, Proform will be a very good and reliable brand to shop from with their different models and machines to consider. What we love from this brand beside the good quality product is the price point for they are typically competitive.

You can get an entry-level with less, basic features only or picking their more dedicated machines in case you will be more serious or looking for a higher impact on the exercise. For those who are in the middle, the most suitable models are Proform 400i and 600i. Both of them are favorite machines from the line and as they are made to be affordably ideal for those who will be spending some of their time exercising at home, you will also get a set of interesting features. 

Similar in many cases, being in the same line makes these treadmills to be very similar to each other because in general what you can do in the little brother will be possible as well on the higher model. What you may want to notice first is that none of Proform 400i and 600i are going to be a great choice if you are more into performance type and will be running in high speed often with the treadmill since they have less speed levels.

Proform 400i and 600i Design

For those who are willing to spend more and will run at higher speed a lot, we do recommend a higher level treadmills such as Nordictrack 1750 Vs 2450. As for the Proform 400i and 600i, these treadmills are ideal for beginner and casual users who are aiming to get enough physical movement right when they are staying at home. Design wise they are the same as any other treadmills in the market with enough running space, a set of feet to hold the surface together, and a handlebar.

Material wise they are not the best but seem robust to sustain the runner body weight and on this side they can be used for up to 300 and 325 lbs. respectively. The 600i in our article today is their newer version instead of the 2015 machine and side by side, you can tell that the big brother is actually bigger in size which translates as a wider running belt as well. They also have different fashion tastes as the 400i use full black shade while the latter still combines the black frame with silver painting.

Proform 400i and 600i Workout

The first thing you may want to know when getting a treadmill is probably the menu as it will provide different types of workout and if you guess the 600i will have more than 400i, it is actually the opposite as the lower version comes with 50 built-in programs instead of 22. The latter is enough for daily workout and to help your body to get enough physical exercise but the former does introduce more to keep you entertained as well.

Similar to many other Proform treadmills, Proform 400i and 600i are suitable with the iFit program and you can pay for their subscription if needed. They may come with a free trial for 30 days but there are many buyers who are picking 600i and get the free coupon for 1-year subscription cant activate their code but if you are going to use the service, there are tons of exercises we can get from their collection.

Proform 400i and 600i Display

Moving further, let’s check out the display in both machines and in this side both of them are also different because you will get a better display quality in 600i yet, the viewing experience is more convenient in 400i since the higher model doesn’t organize the workout data in boxes that usually placed at the top side of the screen in separated and also labeled. When it comes to easy reading, the cheaper treadmill is actually better to give you a straightforward display of basic information.

Proform 400i and 600i Running Belt

The last part we want to talk about and is essential in a treadmill is their belt and as it has been mentioned above that the Proform 600i is actually bigger, this model is also coming with wider running belt at 20 by 60 inches, the same to those higher models that usually cost more than $1k. On the other hand we have to be satisfied with an 18 by 50 inches running belt in Proform 400i. This makes running even more comfortable in the 600i and it allows for up to 12MPH instead of 10.

In addition, Proform 400i and 600i are coming with incline features and they are also different on this side for it can be increased up to 12% on the higher machine and up to 10% for the little brother so we can put more effort and burn more calories.

Proform 400i vs 600i 

Both of these treadmills are a great choice if you are going to spend the time at home but still want to achieve good fitness by exercising routinely. They are also different for in general you will be able to run at a wider running belt and at higher speed with the 600i yet, this model has less convenient display to view basic data and it also somehow only carries less built-in program which reduces its convenience when not being combined with iFit.
