The trapezius is a large paired trapezoid-shaped surface muscle that extends longitudinally from the occipital bone to the lower thoracic vertebrae of the spine and laterally to the spine of the scapula. It moves the scapula and supports the arm.
The scapula, also known as the shoulder blade, is the bone that connects the humerus with the clavicle. Like their connected bones, the scapulae are paired, with each scapula on either side of the body being roughly a mirror image of the other. The name derives from the Classical Latin word for trowel or small shovel, which it was thought to resemble.
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 upper limbs or upper extremities are the forelimbs of an upright-postured tetrapod vertebrate, extending from the scapulae and clavicles down to and including the digits, including all the musculatures and ligaments involved with the shoulder, elbow, wrist and knuckle joints. In humans, each upper limb is divided into the shoulder, arm, elbow, forearm, wrist and hand, and is primarily used for climbing, lifting and manipulating objects. In anatomy, just as arm refers to the upper arm, leg refers to the lower leg.
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 to humiliate and its absence of use for equipment. Variations of push-ups, such as wide-arm push-ups, diamond push-ups target specific muscle groups and provide further challenges.
The pectoralis major is a thick, fan-shaped or triangular convergent muscle of the human chest. It makes up the bulk of the chest muscles and lies under the breast. Beneath the pectoralis major is the pectoralis minor muscle.
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.
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 clean and press is a two-part weight training exercise whereby a loaded barbell is lifted from the floor to the shoulders and pushed overhead. The lift was a component of the sport of Olympic weightlifting from 1928 to 1972, but was removed due to difficulties in judging proper technique.
A bent-over row is a weight training exercise that targets a variety of back muscles depending on the form used. It is often used for both bodybuilding and powerlifting.
The pull-down exercise is a strength training exercise designed to develop the latissimus dorsi muscle. It performs the functions of downward rotation and depression of the scapulae combined with adduction and extension of the shoulder joint.
The upright row is a weight training exercise performed by holding a weight with an overhand grip and lifting it straight up to the collarbone. This is a compound exercise that involves the trapezius, the deltoids and the biceps. The narrower the grip the more the trapezius muscles are exercised, as opposed to the deltoids.
A dip is an upper-body strength exercise. Close grip dips primarily train the triceps, with major synergists being the anterior deltoid, the pectoralis muscles, and the rhomboid muscles of the back. Wide shoulder width dips place 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.
The front raise exercise is used in weight training. It primarily works the anterior deltoid and the clavicular head of the pectoralis major through the use of arm abduction and flexion through the frontal plane. The training volume, or number of sets and repetitions performed, depends on the lifter's training program and goals.
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.
The leg raise is a strength training exercise which targets the iliopsoas. Because the abdominal muscles are used isometrically to stabilize the body during the motion, leg raises are also often used to strengthen the rectus abdominis muscle and the internal and external oblique muscles.
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.
The face pull is a weight training exercise that primarily targets the musculature of the upper back and shoulders, namely the posterior deltoids, trapezius, rhomboids, Latissimus dorsi as well as the biceps. The face pull is considered an important exercise for shoulder health and stability.
