Russian Twist
The Russian twist is a simple abdominal exercise for working the core, shoulders, and hips. It is typically performed in repetitive sets and tones the core muscles via a twisting motion focused around the abdomen. The exercise can help build strength in the upper torso, which may help in sports such as tennis, swimming, baseball and football, track & field, hockey, golf, lacrosse, or boxing. There are also many variations of the Russian twist that can be used to intensify a workout routine. Technique To perform the Russian twist one sits on the floor and bends both knees while feet are kept together and held slightly above the ground (or put under a stable surface). Ideally, the torso is kept straight with the back kept off the ground at a 45-degree angle with arms held together away from the body in a straight fashion and hands kept locked together like a ball or one can hold a weight to increase the difficulty. Next, the arms should be swung from one side to another i ...

Abdominal Exercise
Abdominal exercises are a type of strength exercise that affect the abdominal muscles (colloquially known as the stomach muscles or "abs"). Human abdominal consist of four muscles which are the rectus abdomens, internal oblique, external oblique, and transversus abdominis. When performing abdominal exercises it is important to understand the effects, functions, the types of exercises, and think about how to perform this exercise safely. Effects Abdominal exercises are useful for building abdominal muscles. This is useful for improving performance with certain sports, back pain, and for withstanding abdominal impacts (e.g., taking punches). According to a 2011 study, abdominal muscle exercises are known to increase the strength and endurance of the abdominal muscles. It has been highly disputed whether or not abdominal exercises have any reducing effect on abdominal fat. The aforementioned 2011 study found that abdominal exercise does not reduce abdominal fat; to achieve that, a def ...

Core Stability
In kinesiology, core stability refers to a person's ability to stabilize their Core (anatomy), core (all parts of the Human body, body which are not Limb (anatomy), limbs). Stability, in this context, should be considered as an ability to Motor control, control the position and movement of the core. Thus, if a person has greater core stability, they have a greater level of control over the position and movement of this area of their body. The body's core is frequently involved in aiding other movements of the body, such as running; thus it is known that improving core stability also improves a person's ability to perform these other movements. The body's core region is sometimes referred to as the torso or the trunk, although there are some differences in the muscles identified as constituting them. The major muscles involved in core stability include the pelvic floor muscles, transversus abdominis, multifidus, internal obliques, internal and external obliques, rectus abdominis, e ...

Torso
The torso or trunk is an anatomical term for the central part, or the core, of the body of many animals (including humans), from which the head, neck, limbs, tail and other appendages extend. The tetrapod torso — including that of a human — is usually divided into the ''thoracic'' segment (also known as the upper torso, where the forelimbs extend), the ''abdominal'' segment (also known as the "mid-section" or "midriff"), and the ''pelvic'' and '' perineal'' segments (sometimes known together with the abdomen as the lower torso, where the hindlimbs extend). Anatomy Major organs In humans, most critical organs, with the notable exception of the brain, are housed within the torso. In the upper chest, the heart and lungs are protected by the rib cage, and the abdomen contains most of the organs responsible for digestion: the stomach, which breaks down partially digested food via gastric acid; the liver, which respectively produces bile necessary for digestion; the large and ...

Tennis
Tennis is a racket sport that is played either individually against a single opponent ( singles) or between two teams of two players each ( doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball validly will not gain a point, while the opposite player will. Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections both to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. The rules of modern tennis have ...

Swimming (sport)
Swimming is an individual or team racing sport that requires the use of one's entire body to move through water. The sport takes place in pools or open water (e.g., in a sea or lake). Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. A medley relay consists of four swimmers who will each swim a different stroke, ordered as backstroke, breaststroke, butterfly and freestyle. Swimming each stroke requires a set of specific techniques; in competition, there are distinct regulations concerning the acceptable form for each individual stroke. There are also regulations on what types of swimsuits, caps, jewelry and injury tape that are allowed at competitions. Although it is possible for competitive swimmers to incur several injuries from the sport, such as te ...

Baseball
Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play generally beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a bat. The objective of the offensive team (batting team) is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called " runs". The objective of the defensive team (referred to as the fielding team) is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter). The principal objective of the batting team is to have a ...

Football
Football is a family of team sports that involve, to varying degrees, kicking a ball to score a goal. Unqualified, the word ''football'' normally means the form of football that is the most popular where the word is used. Sports commonly called ''football'' include association football (known as ''soccer'' in North America and Australia); gridiron football (specifically American football or Canadian football); Australian rules football; rugby union and rugby league; and Gaelic football. These various forms of football share to varying extent common origins and are known as "football codes". There are a number of references to traditional, ancient, or prehistoric ball games played in many different parts of the world. Contemporary codes of football can be traced back to the codification of these games at English public schools during the 19th century. The expansion and cultural influence of the British Empire allowed these rules of football to spread to areas of British ...

Track And Field
Track and field is a sport that includes athletic contests based on running, jumping, and throwing skills. The name is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and racewalking. The foot racing events, which include sprints, middle- and long-distance events, racewalking, and hurdling, are won by the athlete who completes it in the least time.

Hockey
Hockey is a term used to denote a family of various types of both summer and winter team sports which originated on either an outdoor field, sheet of ice, or dry floor such as in a gymnasium. While these sports vary in specific rules, numbers of players, apparel and, notably, playing surface, they share broad characteristics of two teams playing against each other to propel a ball or disk into a goal with a stick. There are many types of hockey. Some games make the use of skates, either wheeled, or bladed while others do not. In order to help make the distinction between these various games, the word "hockey" is often preceded by another word i.e. "field hockey", "ice hockey", " roller hockey", "rink hockey", or "floor hockey". In each of these sports, two teams play against each other by trying to manoeuvre the object of play, either a type of ball or a disk (such as a puck), into the opponent's goal using a hockey stick. Two notable exceptions use a straight stick and an op ...

Golf
Golf is a club-and-ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible. Golf, unlike most ball games, cannot and does not use a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. Courses typically have either 18 or 9 ''holes'', regions of terrain that each contain a ''cup'', the hole that receives the ball. Each hole on a course contains a teeing ground to start from, and a putting green containing the cup. There are several standard forms of terrain between the tee and the green, such as the fairway, rough (tall grass), and various ''hazards'' such as water, rocks, or sand-filled ''bunkers''. Each hole on a course is unique in its specific layout. Golf is played for the lowest number of strokes by an individual, known as stroke play, or the lowest score on the most individual holes in a complete round by an individual or team, k ...

Lacrosse
Lacrosse is a team sport played with a lacrosse stick and a lacrosse ball. It is the oldest organized sport in North America, with its origins with the indigenous people of North America as early as the 12th century. The game was extensively modified by European colonists, reducing the violence, to create its current collegiate and professional form. Players use the head of the lacrosse stick to carry, pass, catch, and shoot the ball into the goal. The sport has four versions that have different sticks, fields, rules and equipment: field lacrosse, women's lacrosse, box lacrosse and intercrosse. The men's games, field lacrosse (outdoor) and box lacrosse (indoor), are contact sports and all players wear protective gear: helmet, gloves, shoulder pads, and elbow pads. The women's game is played outdoors and does not allow body contact but does allow stick to stick contact. The only protective gear required for women players is eyegear, while goalies wear helmets and protective p ...

Boxing
Boxing (also known as "Western boxing" or "pugilism") is a combat sport in which two people, usually wearing protective gloves and other protective equipment such as hand wraps and mouthguards, throw punches at each other for a predetermined amount of time in a boxing ring. Although the term "boxing" is commonly attributed to "western boxing", in which only the fists are involved, boxing has developed in various ways in different geographical areas and cultures. In global terms, boxing is a set of combat sports focused on striking, in which two opponents face each other in a fight using at least their fists, and possibly involving other actions such as kicks, elbow strikes, Knee (strike), knee strikes, and headbutts, depending on the rules.
