Callisthenics
Calisthenics (American English) or callisthenics (British English) ( /ˌkælɪsˈθɛnɪks/) is a form of strength training consisting of a variety of movements that exercise large muscle groups (gross motor movements), such as standing, grasping, pushing, etc. These exercises are often performed rhythmically and with minimal equipment, as bodyweight exercises. They are intended to increase strength, fitness, and flexibility, through movements such as pulling, pushing, bending, jumping, or swinging, using one's body weight for resistance. Calisthenics can provide the benefits of muscular and aerobic conditioning, in addition to improving psychomotor skills such as balance, agility, and coordination. Urban calisthenics is a form of street workout; calisthenics groups perform exercise routines in urban areas. Individuals and groups train to perform advanced calisthenics skills such as muscle-ups, levers, and various freestyle moves such as spins and flips. Sports teams and milit ...

Battle Of Thermopylae
The Battle of Thermopylae ( ; grc, Μάχη τῶν Θερμοπυλῶν, label=Greek, ) was fought in 480 BC between the Achaemenid Persian Empire under Xerxes I and an alliance of Greek city-states led by Sparta under Leonidas I. Lasting over the course of three days, it was one of the most prominent battles of both the second Persian invasion of Greece and the wider Greco-Persian Wars. The engagement at Thermopylae occurred simultaneously with the Battle of Artemisium: between July and September 480 BC. The second Persian invasion under Xerxes I was a delayed response to the failure of the first Persian invasion, which had been initiated by Darius I and ended in 490 BC by an Athenian-led Greek victory at the Battle of Marathon. By 480 BC, a decade after the Persian defeat at Marathon, Xerxes had amassed a massive land and naval force, and subsequently set out to conquer all of Greece. In response, the Athenian politician and general Themistocles proposed that the allie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Push-up
The push-up (sometimes called a press-up in British English) 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. Etymology The American English term ''push-up'' was first used between 1905 and 1910, while the British ''press-up'' was first recorded between 1945 and 1950. Body mass supported during push-ups According to the study published in Journal of Strength and Conditioning Research, the test subjects supported with their hands, on average, 69.16% of their body mass in the ...

Dip (exercise)
A dip is an upper-body strength exercise. Narrow, shoulder-width dips mainly trains the triceps, with major synergists being the anterior deltoid, the pectoralis muscles, and the rhomboid muscles of the back. Wide arm training places additional emphasis on the pectoral muscles, similar in respect to the way a wide grip bench press would focus more on the pectorals and less on the triceps. Modern meaning To perform a dip, the exerciser supports themselves on a dip bar with their arms straight down and shoulders over their hands, then lowers their body until their arms are bent to a 90 degree angle at the elbows, and then lifts their body up, returning to the starting position. Variation Usually dips are done on a dip bar, with the exerciser's hands supporting their entire body weight. For added resistance, weights can be added by use of a dip belt, weighted vest, or by wearing a backpack with weights in it. A dumbbell may also be held between the knees or ankles. For less resis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latissimus Dorsi Muscle
The latissimus dorsi () is a large, flat muscle on the back that stretches to the sides, behind the arm, and is partly covered by the trapezius on the back near the midline. The word latissimus dorsi (plural: ''latissimi dorsorum'') comes from Latin and means "broadest uscleof the back", from "latissimus" ( la, broadest)' and "dorsum" ( la, back). The pair of muscles are commonly known as "lats", especially among bodybuilders. The latissimus dorsi is the largest muscle in the upper body. The latissimus dorsi is responsible for extension, adduction, transverse extension also known as horizontal abduction (or horizontal extension), flexion from an extended position, and (medial) internal rotation of the shoulder joint. It also has a synergistic role in extension and lateral flexion of the lumbar spine. Due to bypassing the scapulothoracic joints and attaching directly to the spine, the actions the latissimi dorsi have on moving the arms can also influence the movement of the sca ...

Biceps
The biceps or biceps brachii ( la, musculus biceps brachii, "two-headed muscle of the arm") is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. Both heads of the muscle arise on the scapula and join to form a single muscle belly which is attached to the upper forearm. While the biceps crosses both the shoulder and elbow joints, its main function is at the elbow where it flexes the forearm and supinates the forearm. Both these movements are used when opening a bottle with a corkscrew: first biceps screws in the cork (supination), then it pulls the cork out (flexion). Structure The biceps is one of three muscles in the anterior compartment of the upper arm, along with the brachialis muscle and the coracobrachialis muscle, with which the biceps shares a nerve supply. The biceps muscle has two heads, the short head and the long head, distinguished according to their origin at the coracoid process and supraglenoid tubercle of the sc ...

Chin-up Bar
A pull-up is an upper-body strength exercise. The pull-up is a closed-chain movement where the body is suspended by the hands, gripping a bar or other implement at a distance typically wider than shoulder-width, and pulled up. As this happens, the elbows flex and the shoulders adduct and extend to bring the elbows to the torso. Pull-ups build up several muscles of the upper body, including the latissimus dorsi, trapezius, and biceps brachii. A pull-up may be performed with overhand (pronated), underhand (supinated)—sometimes referred to as a chin-up—neutral, or rotating hand position. Pull-ups are used by some organizations as a component of fitness tests, and as a conditioning activity for some sports. Movement Beginning by hanging from the bar, the body is pulled up vertically. From the top position, the participant lowers their body until the arms and shoulders are fully extended. The end range of motion at the top end may be chin over bar or higher, such as chest to ...

Burpee (exercise)
The burpee, a squat thrust with an additional stand between repetitions, is a full body exercise used in strength training. The movement itself is primarily an anaerobic exercise, but when done in succession over a longer period can be utilized as an aerobic exercise. The basic movement as described by its namesake, physiologist Royal H. Burpee, is performed in four steps from a standing position and known as a "four-count burpee": # Move into a squat position with your hands on the ground. # Kick your feet back into an extended plank position, while keeping your arms extended. # Immediately return your feet into squat position. # Stand up from the squat position. You can make this exercise modified by stepping back into a plank instead Moves 2 and 3 constitute a squat thrust. Many variants of the basic burpee exist, and they often include a push-up and a jump. Origin The exercise was invented in 1939 by US physiologist Royal Huddleston Burpee Sr., who used it in the ...

Gluteal Muscles
The gluteal muscles, often called glutes are a group of three muscles which make up the gluteal region commonly known as the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur. The functions of the muscles include extension, abduction, external rotation, and internal rotation of the hip joint. Structure The gluteus maximus is the largest and most superficial of the three gluteal muscles. It makes up a large part of the shape and appearance of the hips. It is a narrow and thick fleshy mass of a quadrilateral shape, and forms the prominence of the buttocks. The gluteus medius is a broad, thick, radiating muscle, situated on the outer surface of the pelvis. It lies profound to the gluteus maximus and its posterior third is covered by the gluteus maximus, its anterior two-thirds by the gluteal aponeurosis, which separates it from the superficial fascia and skin. The gluteus minimus is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
