In human anatomy, the arm refers to the upper limb in common usage, although academically the term specifically means the upper arm between the glenohumeral joint and the elbow joint. The distal part of the upper limb between the elbow and the radiocarpal joint is known as the forearm or "lower" arm, and the extremity beyond the wrist is the hand.
Calisthenics or callisthenics (/ˌkælɪsˈθɛnɪk/) is a form of strength training that utilizes an individual's body weight as resistance to perform multi-joint, compound movements with little or no equipment.
The human shoulder is made up of three bones: the clavicle (collarbone), the scapula, and the humerus as well as associated muscles, ligaments and tendons.
The deltoid muscle is the muscle forming the rounded contour of the human shoulder. It is also known as the 'common shoulder muscle', particularly in other animals such as the domestic cat. Anatomically, the deltoid muscle is made up of three distinct sets of muscle fibers, namely the
- anterior or clavicular part
- posterior or scapular part
- intermediate or acromial part
The bench press or chest press is a weight training exercise where a person presses a weight upwards while lying horizontally on a weight training bench. The bench press is a compound movement, with the primary muscles involved being the pectoralis major, the anterior deltoids, and the triceps brachii. Other muscles located in the back, legs and core are involved for stabilization. A barbell is generally used to hold the weight, but a pair of dumbbells can also be used.
The push-up is a common calisthenics exercise beginning from the prone position. By raising and lowering the body using the arms, push-ups exercise the pectoral muscles, triceps, and anterior deltoids, with ancillary benefits to the rest of the deltoids, serratus anterior, coracobrachialis and the midsection as a whole. Push-ups are a basic exercise used in civilian athletic training or physical education and commonly in military physical training. They are also a common form of punishment used in the military, school sport, and some martial arts disciplines. Variations of push-ups, such as wide-arm push-ups, diamond push-ups target specific muscle groups and provide further challenges.
A handstand is the act of supporting the body in a stable, inverted vertical position by balancing on the hands. In a basic handstand, the body is held straight with arms and legs fully extended, with hands spaced approximately shoulder-width apart and the legs together. There are many variations of handstands, all of which require the performer to possess adequate balance and upper body strength.
Bicep curls are a group of weight training exercises in which a person bends their arm towards their body at the elbow in order to make their biceps stronger.
A squat is a strength exercise in which the trainee lowers their hips from a standing position and then stands back up. During the descent, the hip and knee joints flex while the ankle joint dorsiflexes; conversely the hip and knee joints extend and the ankle joint plantarflexes when standing up. Squats also help the hip muscles.
The bridge is an exercise. Many variations of this exercise are employed throughout the world, most commonly the balancing of the body on the hands and the feet. It is intended to improve lower back and gluteus strength. Examples of bridging in sportive or self-defense applications are seen in Kung Fu, Judo, Brazilian jiu jitsu, Capoeira, mixed martial arts, and wrestling.
The lying triceps extension, also known as skull crusher and French extension or French press, is a strength exercise used in many different forms of strength training. It is one of the most stimulating exercises to the entire triceps muscle group in the upper arm, and works the triceps from the elbow all the way to the latissimus dorsi. Due to its full use of the triceps muscle group, the lying triceps extensions are used by many as part of their training regimen.
The shoulder joint is structurally classified as a synovial ball-and-socket joint and functionally as a diarthrosis and multiaxial joint. It involves an articulation between the glenoid fossa of the scapula and the head of the humerus. Due to the very loose joint capsule ,that gives a limited interface of the humerus and scapula, it is the most mobile joint of the human body.
The following outline is provided as an overview of and topical guide to exercise:
A fly or flye is a strength training exercise in which the hand and arm move through an arc while the elbow is kept at a constant angle. Flies are used to work the muscles of the upper body. Because these exercises use the arms as levers at their longest possible length, the amount of weight that can be moved is significantly less than equivalent press exercises for the same muscles . Due to this leverage, fly exercises of all types have a large potential to damage the shoulder joint and its associated ligaments and the tendons of the muscles connecting to it. They should be done with caution and their effects first tested while using very light weights; which are gradually incremented after more strength is gained.
The front lever is a gymnastic and calisthenic move - a static hold normally performed on the still rings or the pull-up bar. A front lever is performed by lowering from an inverted hang until the body is completely horizontal and straight with the front of the body facing upwards. An accomplished gymnast may also pull directly into the horizontal position from a dead hang. Front levers require a high degree of back and core strength.
The rear delt raise, also known as the rear deltoid raise, or rear shoulder raise is an exercise in weight training. This exercise is an isolation exercise that heavily works the posterior deltoid muscle. The movement is primarily limited to the two shoulder joints: the glenohumeral joint and the scapulothoracic joint. Scapular movement will also cause movement in the sternoclavicular joint and acromioclavicular joint. If the elbow bends during the extension exercises, it gravitates into a rowing motion.
A machine fly, alternatively called a seated lever fly or "pec deck" fly is a strength training exercise based on the free weight chest fly. As with the chest fly, the hand and arm move through an arc while the elbow is kept at a constant angle. Flyes are used to work the muscles of the upper body, primarily the sternal head of the pectoralis major. Because these exercises use the arms as levers at their longest possible length, the amount of weight that can be moved is significantly less than equivalent press exercises for the same muscles. Denie Walter is credited with calling it the Peck Dec back in the 1970s.
Upper-limb surgery in tetraplegia includes a number of surgical interventions that can help improve the quality of life of a patient with tetraplegia.
The plank is an isometric core strength exercise that involves maintaining a position similar to a push-up.
