Fitbit Charge 2 Bands Replacement Sport Strap Accessories with Fasteners and Metal Clasps for Fitbit Charge 2 Wristband (Small, BrightRed)

2 (two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and the only even prime number.

Because it forms the basis of a duality, it has religious and spiritual significance in many cultures.

Fitbit is a line of wireless-enabled wearable technology, physical fitness monitors and activity trackers such as smartwatches, pedometers and monitors for heart rate, quality of sleep, and stairs climbed as well as related software. It operated as an American consumer electronics and fitness company from 2007 to 2021.

The Fitbit brand name was originally owned by Fitbit, Inc., founded by James Park and Eric Freidman. The company was acquired by Google in January 2021 and was absorbed into the company's hardware division.

In 2019, Fitbit was the fifth largest wearable technology company in shipments. The company has sold more than 120 million devices and has 29 million users in over 100 countries.

A metal (from Ancient Greek μέταλλον (métallon) 'mine, quarry, metal') is a material that, when polished or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. These properties are all associated with having electrons available at the Fermi level, as against nonmetallic materials which do not.^{: Chpt 8 & 19 : Chpt 7 & 8} Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets).

A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. The general science of metals is called metallurgy, a subtopic of materials science; aspects of the electronic and thermal properties are also within the scope of condensed matter physics and solid-state chemistry, it is a multidisciplinary topic. In colloquial use materials such as steel alloys are referred to as metals, while others such as polymers, wood or ceramics are nonmetallic materials.

A metal conducts electricity at a temperature of absolute zero, which is a consequence of delocalized states at the Fermi energy. Many elements and compounds become metallic under high pressures, for example, iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Sodium becomes a nonmetal at pressure of just under two million times atmospheric pressure, and at even higher pressures it is expected to become a metal again.

When discussing the periodic table and some chemical properties the term metal is often used to denote those elements which in pure form and at standard conditions are metals in the sense of electrical conduction mentioned above. The related term metallic may also be used for types of dopant atoms or alloying elements.

In astronomy metal refers to all chemical elements in a star that are heavier than helium. In this sense the first four "metals" collecting in stellar cores through nucleosynthesis are carbon, nitrogen, oxygen, and neon. A star fuses lighter atoms, mostly hydrogen and helium, into heavier atoms over its lifetime. The metallicity of an astronomical object is the proportion of its matter made up of the heavier chemical elements.

The strength and resilience of some metals has led to their frequent use in, for example, high-rise building and bridge construction, as well as most vehicles, many home appliances, tools, pipes, and railroad tracks. Precious metals were historically used as coinage, but in the modern era, coinage metals have extended to at least 23 of the chemical elements. There is also extensive use of multi-element metals such as titanium nitride or degenerate semiconductors in the semiconductor industry.

The history of refined metals is thought to begin with the use of copper about 11,000 years ago. Gold, silver, iron (as meteoric iron), lead, and brass were likewise in use before the first known appearance of bronze in the fifth millennium BCE. Subsequent developments include the production of early forms of steel; the discovery of sodium—the first light metal—in 1809; the rise of modern alloy steels; and, since the end of World War II, the development of more sophisticated alloys.

Sport is a form of physical activity or game. Often competitive and organized, sports use, maintain, or improve physical ability and skills. They also provide enjoyment to participants and, in some cases, entertainment to spectators. Many sports exist, with different participant numbers, some are done by a single person with others being done by hundreds. Most sports take place either in teams or competing as individuals. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner. A number of contests may be arranged in a tournament format, producing a champion. Many sports leagues make an annual champion by arranging games in a regular sports season, followed in some cases by playoffs.

Sport is generally recognised as system of activities based in physical athleticism or physical dexterity, with major competitions admitting only sports meeting this definition. Some organisations, such as the Council of Europe, preclude activities without any physical element from classification as sports. However, a number of competitive, but non-physical, activities claim recognition as mind sports. The International Olympic Committee who oversee the Olympic Games recognises both chess and bridge as sports. SportAccord, the international sports federation association, recognises five non-physical sports: chess, bridge, draughts, Go and xiangqi. However, they limit the number of mind games which can be admitted as sports. Sport is usually governed by a set of rules or customs, which serve to ensure fair competition. Winning can be determined by physical events such as scoring goals or crossing a line first. It can also be determined by judges who are scoring elements of the sporting performance, including objective or subjective measures such as technical performance or artistic impression.

Records of performance are often kept, and for popular sports, this information may be widely announced or reported in sport news. Sport is also a major source of entertainment for non-participants, with spectator sport drawing large crowds to sport venues, and reaching wider audiences through broadcasting. Sport betting is in some cases severely regulated, and in others integral to the sport.

According to A.T. Kearney, a consultancy, the global sporting industry is worth up to $620 billion as of 2013. The world's most accessible and practised sport is running, while association football is the most popular spectator sport.

A strap, sometimes also called strop, is an elongated flap or ribbon, usually of leather or other flexible materials.

Thin straps are used as part of clothing or baggage, or bedding such as a sleeping bag. See for example spaghetti strap, shoulder strap. A strap differs from a belt mainly in that a strap is usually integral to the item of clothing; either can be used in combination with buckles.

Straps are also used as fasteners to attach, secure, carry, or bind items, to objects, animals (for example a saddle on a horse) and people (for example a watch on a wrist), or even to tie down people and animals, as on an apparatus for corporal punishment. Occasionally a strap is specified after what it binds or holds, e.g. chin strap. Webbing is a particular type of strap that is a strong fabric woven as a flat strip or tube that is also often used in place of rope. Modern webbing is typically made from exceptionally high-strength material and is used in automobile seat belts, furniture manufacturing, transportation, towing, military uniform, cargo fasteners, and many other fields.

With or WITH may refer to:

Wristbands are encircling strips worn on the wrist or lower forearm. The term may refer to a bracelet-like band, similar to that of a wristwatch, to the cuff or other part of a sleeve that covers the wrist, or decorative or functional bands worn on the wrist for many different reasons. Wristbands are often worn and used similarly to event passes such as lanyards to information or allow people entry to events. These wristbands are made from loops of plastic that are placed around the wrist and are used for identification purposes (demonstrating the wearer's authorization to be at a venue, for example).

Another type of wristband is the sweatband; usually made of a towel-like terrycloth material. These are usually used to wipe sweat from the forehead during sport but have been known to be used as a badge or fashion statement. A practice common in mid-1980s punk subculture was to cut the top off of a sock and fashion the elastic into this type of wristband.
