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, [citation needed] and works the triceps from the elbow all the way to the ...
Lateral head. Medial head. The triceps, or triceps brachii (Latin for "three-headed muscle of the arm"), is a large muscle on the back of the upper limb of many vertebrates. It consists of 3 parts: the medial, lateral, and long head. [1] It is the muscle principally responsible for extension of the elbow joint (straightening of the arm).
A push-down is a strength training exercise used for strengthening the triceps muscles in the back of the arm. This exercise can also be called a triceps push-down or a two-armed standing triceps extension. The exercise is completed by pushing an object downward against resistance. This exercise is an example of the primary function of the ...
The triceps extension is performed while standing or seated, by lowering a weight held above the head (keeping the upper arms motionless), and then raising it again. It can be performed with both arms, or one arm at a time. This is an isolation exercise for the triceps. It is also known as the french curl.
Push-up. Animation of a full push-up (the wide positioning of the hands increases the push-up's use of chest muscles as opposed to arm muscles) Side view of a push-up. Push-up technique. The push-up (press-up in British English) is a common calisthenics exercise beginning from the prone position. By raising and lowering the body using the arms ...
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 ...
For example, the triceps brachii contracts, producing a shortening (concentric) contraction, during the up phase of a push-up (elbow extension). During the down phase of a push-up, the same triceps brachii actively controls elbow flexion while producing a lengthening (eccentric) contraction. It is still the agonist, because while resisting ...
Triceps reflex. The triceps reflex, a deep tendon reflex, is a reflex that elicits involuntary contraction of the triceps brachii muscle. It is sensed and transmitted by the radial nerve. [1] The reflex is tested as part of the neurological examination to assess the sensory and motor pathways within the C7 and C8 spinal nerves.
