Obesity is a worldwide pandemic that's on the rise.
Worldwide, obesity has nearly doubled in frequency since 1980.
Almost 2 billion of the adults in the world were overweight in 2014 - 600 million of which were considered obese.
Overweight people, as defined by the World Health Organization, have a body mass index (BMI) of over 25.
Obese people have a BMI of over 30.
Obesity results when a person has an excess of fat in their body.
This can be caused by overeating, or simply having a bad diet and not exercising.
Obesity can also be hereditary. A slow metabolism can be passed on through genetics, which results in the body not being able to burn calories fast enough.
Excess calories are stored as fat in the human body.
Obesity can be prevented in several ways. It can be as simple as changing your diet if you're prone to overeating, or simply eat healthier foods if you overindulge on junk food.
For the most extreme cases of obesity, liposuction – medical removal of extra weight – can be necessary.
Exercising has a number of benefits that extend beyond simple weight loss.
Popular Equipment Used for Exercising and Losing Weight
Treadmills are the most common pieces of weight loss equipment. They're used extensively across the world.
Exercise bicycles simulate bicycling and allow you to burn a huge amount of calories. Exercise bicycles can be used indoors, allowing for fans of biking doing it indoors when the weather's bad.
Portable stairs simulate walking or running up stairs. This is a simple but repetitive motion that can burn a lot of calories.
What is a treadmill?
A treadmill is a machine that allows someone to run in place.Treadmills have had various uses through history since their invention in the early 1800s.
They were originally used as a device to harvest the power of humans for labor.
They were used for productivity in factories and mills, or as punishments in prisons.
Treadmills generally feature a continuously running belt that is fitted onto a wheel. The wheel turns when the conveyor belt moves by the motion of walking or running – allowing for people to generate power proportionate to the effort they exert.
As obesity began to become a more common problem, people realized that the treadmill is a great way of losing weight.
Nowadays, treadmills used for exercise are powered electrically. The continuous movement of the belt is powered by a motor.
This allows a person to run or walk in place for long periods, without exerting too much energy by having to move the belt themselves.
Modern treadmills have different settings.
Speed can be adjusted for different speeds of running, and adjusting the elevation can simulate running uphill.
Treadmills are tremendously popular options for people hoping to lose weight.
Treadmills are used ubiquitously: at universities, public gyms, running facilities, hospitals, and health rehabilitation units - even NASA's training programs utilize treadmills.
Treadmills are the most frequently sold exercise units in America, and often the first recommendation for someone looking to find a piece of equipment to use for losing weight.
Treadmills have two main varieties
Manual treadmills are not powered by electricity. Instead, the motion of the belt is controlled by the speed of the person running or walking on the treadmill.
This means that manual treadmills are much more exhausting when used for exercise.
Automatic treadmills are powered by motors and allow speed and elevation to be controlled by the user. This allows the user to exercise for longer periods of cardio exercise.
Pros and cons of treadmills
What is an Elliptical machine?
Elliptical trainers are the proper name for the stair-climbing machines mentioned earlier in the article.
They can simulate running, walking, and climbing stairs on a place.
Elliptical machines are actually much safer than running or walking outside, since they're built to prevent injuries from repetitive strain.
Because of this, they are also an option for some people who have injured themselves and aren't able to run outdoor.
Elliptical trainers are not as popular as treadmills. The first elliptical trainers were marketed in the early 1990s – making them a much more recent discovery than the treadmill.
Treadmills have been around for just over two centuries.
Much like treadmills, elliptical machines have motorized and non-motorized versions. Different settings can be applied, allowing people to personalize their workout routines.
Different models have different prices, and the more expensive ones have more complex settings.
All elliptical machines are built around the same basic premise: pedals are attached to what is known as a four-bar linkage.The user's weight moves the pedals, which rotate on the link to create motion.
Types of Elliptical Machines
Manual elliptical trainers do not have motors. These aren't very common since they require a huge amount of effort to use, and are not often seen in gyms or even as home exercise machines.
Elliptical gliders are built a bit differently than other elliptical training devices. The 'pedals' are attached to a stationary bar and are swung in semi-circular motions.
They typically require less resistance than other elliptical machines and aren't as intensive or effective at burning calories.
Automatic elliptical machines are powered by motors and are much more common than manual machines.
Automatic elliptical machines allow the user to customize their exercise routine by adjusting certain settings.
Like a treadmill, you can adjust the resistance to create a tougher workout, or create a simulated incline.
Automatic machines cater to people who have specific needs in their exercise programs.
There are a couple different types of automatic ellipticals:
Elliptical trainers are standard elliptical exercise machines. The machine operates by a person simply applying their weight to the pedals, creating a circular (elliptical) motion. This requires the extension of the knee and hip, working the hamstrings, quads, and glutes.
Elliptical cross-trainers have the same foundation as a regular elliptical trainer. In addition to the pedals, they also have moving arms. This allows a user to work both their upper and lower bodies. The best way to do this is by creating an alternating pattern of movement between the upper and lower body. Cross-trainers allow a user to work not just with their legs, but their shoulders and back muscles.
There are quite a few pros that come with using elliptical machines. A lot of people consider them more effective than treadmills – they share many of the same benefits, as well as some additional ones.
What Should You Chose: Treadmill or elliptical for weight loss?
On the surface, ellipticals and treadmills look like very different machines.
Despite this, an elliptical allows you to perform pretty much any type of exercise that you can on a treadmill – and then some.
Elliptical trainers put less strain on the body while offering a greater range of exercise techniques.
Considering both machines are in a similar price range, the elliptical is more practical.
Ellipticals do less damage to your body, are just as effective at burning calories.
Both have the same benefits of being safe for use regardless of weather, their customization for exercise.
