Exercise Bicycle
A stationary bicycle (also known as exercise bicycle, exercise bike, spinning bike, spin bike, or exercycle) is a device used as exercise equipment for indoor cycling. It includes a saddle, pedals, and some form of handlebars arranged as on a (stationary) bicycle. A stationary bicycle is usually a special-purpose exercise machine resembling a bicycle without wheels. It is also possible to adapt an ordinary bicycle for stationary exercise by placing it on bicycle rollers or a trainer. Rollers and trainers are often used by racing cyclists to warm up before racing, or to train on their own machines indoors. History The ancestors of modern stationary bicycles date back to the end of the eighteenth century. The Gymnasticon was an early example. Types Some models feature handlebars that are connected to the pedals so that the upper body can be exercised along with the lower body. Most exercise bikes provide a mechanism for applying resistance to the pedals which increas ...

Friction
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: *Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into ''static friction'' ("stiction") between non-moving surfaces, and ''kinetic friction'' between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities (see Figure 1). *Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. *Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. *Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. *Internal friction is the force resisting motion between the elements making up a so ...

Zwift
Zwift is a massively multiplayer online cycling and running physical training program that enables users to interact, train, and compete in a virtual world. Zwift was developed by Zwift Inc., which was co-founded by Jon Mayfield, Eric Min, Scott Barger, and Alarik Myrin, in California, United States, North America, in 2014. The Zwift game was released in its beta version in September 2014, in partnership with TRUE Communications/InGoodTaste, and became a paid product with a fee of US$10 per month in October 2015 (). They raised their monthly membership to US$14.99 in November 2017 (). Early history In 2012/13 Eric Min had recently sold his previous company, Sakonnet Technology. Min, a lifelong cyclist, found himself confined to riding indoors, and dissatisfied with current interactive options, he believed he could improve on them by "making cycling social". Around this time, Min saw an online post by programmer Jon Mayfield describing a "3D trainer program" he was developing ...

Outline Of Cycling
:''This article is an outline about the activity of cycling. For an outline about bicycles themselves, see outline of bicycles.'' :The following ''outline'' is provided as an overview of, as well as a topical guide to cycling: Cycling, also called bicycling or biking, is the activity of using / riding bicycles, (at least partially) human-powered, wheeled vehicles (typically by foot pedalling), for purposes including transport, recreation, social interaction, exercise, sport, therapy, other purposes, or any combination thereof. Persons engaged in cycling are called cyclists, bikers, or sometimes bicyclists. They typically either dress for where they are going, or for the cycling, sometimes having another set of clothing with them, or arranged. Apart from regular two-wheeled bicycles, cycling also includes riding unicycles, tricycles, quadricycles, and other similar human-powered wheeled vehicles (HPVs). Some bicycles are sold with (electric) motors (e-bikes), or ot ...

Elliptical Trainer
An elliptical trainer or cross-trainer is a stationary exercise machine used to stair climb, walk, or run without causing excessive pressure to the joints, hence decreasing the risk of impact injuries. For this reason, people with some injuries can use an elliptical to stay fit, as the low impact affects them little. Elliptical trainers offer a non-impact cardiovascular workout that can vary from light to high intensity based on the speed of the exercise and the resistance preference set by the user. Elliptical trainers first entered the market in the 1990s, invented by Precor. Most elliptical trainers work the user's upper and lower body (although some models do not have moving upper body components). Though elliptical trainers are considered to be minimal-impact, they are an example of a weight-bearing form of exercise. They can be self-powered by user-generated motion or need to be plugged in for adjustment of motion and/or for supplying their electronic consoles and resis ...

Bicycle Trainer
A bicycle trainer is a piece of equipment that makes it possible to ride a bicycle while it remains stationary. They are commonly used to warm up before races, or when riding conditions outside are not favorable. Operation A trainer consists of a frame, a clamp to hold the bicycle securely, a roller that presses up against the rear wheel, and a mechanism that provides resistance when the pedals are turned. In a wind trainer, the roller drives fan blades that create air resistance. These are typically the least expensive and noisiest trainers. Magnetic trainers have magnets and a conducting flywheel operating as an eddy current brake. They are moderately expensive and moderately noisy. Some magnetic trainers have handlebar-mounted control boxes to change the level of resistance during a training session. Fluid trainers use liquid-filled chambers to create resistance. They are the most expensive and quietest trainers. A small number of trainers use a centrifugal pressure mecha ...

Weight Loss
Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, by a mean loss of fluid, body fat (adipose tissue), or lean mass (namely bone mineral deposits, muscle, tendon, and other connective tissue). Weight loss can either occur unintentionally because of malnourishment or an underlying disease, or from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or exercise is called cachexia and may be a symptom of a serious medical condition. Intentional Intentional weight loss is the loss of total body mass as a result of efforts to improve physical fitness, fitness and health, or to change Human physical appearance, appearance through slimming. Weight loss is the main Management of obesity, treatment for obesity, and there is substantial evidence this can prevent progression from prediabetes to Diabetes mellitus, ty ...

Gold's Gym Folding Upper & Lower Body Cycle With Monitor
Gold and Company (Gold's) was a department store located in downtown Lincoln, Nebraska. The store was founded in 1915 and quickly grew into one of Lincoln's dominant retailers throughout the 20th century. Gold's merged with the Brandeis department store in 1964 and closed in 1980. History Gold and Company was founded by William Gold. The original name was The Peoples' Store until Gold incorporated with his son in 1915, officially naming it Gold and Company. The department store had one location in Lincoln, Nebraska, which was built in 1924. The building grew as the business grew with additions in 1929, 1947, and 1951. Acquisition by Brandeis An Omaha-based department store Brandeis merged with Gold's in 1964 to become Brandeis, Gold's Division. Brandeis operated the store for several years until 1980 when the company was shattered also forcing them to sell the downtown Omaha Brandeis flagship shortly after. The former Gold's building is now Gold's Galleria, a mix of retail store ...

Men And Women On Exercise Bikes (Source)
A man is an adult male human. Prior to adulthood, a male human is referred to as a boy (a male child or adolescent). Like most other male mammals, a man's genome usually inherits an X chromosome from the mother and a Y chromosome from the father. Sex differentiation of the male fetus is governed by the SRY gene on the Y chromosome. During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics, thus exhibiting greater differences between the sexes. These include greater muscle mass, the growth of facial hair and a lower body fat composition. Male anatomy is distinguished from female anatomy by the male reproductive system, which includes the penis, testicles, sperm duct, prostate gland and the epididymis, and by secondary sex characteristics, including a narrower pelvis, narrower hips, and smaller breasts without mammary glands. Throughout human history, traditional gender roles have often defined an ...

Bearing (mechanical)
A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may ''prevent'' a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts. Rotary bearings hold rotating components such as shafts or axles within mechanical systems, and transfer axial and radial loads from the source of the load to the structure supporting it. The simplest form of bearing, the ''plain bearing'', consists of a shaft rotating in a hole. Lubrication is used to reduce friction. In the ''ball bearing'' and ''roller bearing'', to reduce sliding ...
