Introduction
According to Wikipedia (n. d) this exercise involves the curling motion where a weight attached to a barbell (ranging from 1.2m to 2.4m) is moved through an arc, primarily using the strength of the biceps. The first part of the motion is when the elbows begin in full extension, in an overhand grip. The biceps contract to lift the weight upward through an arc, to a point where further movement is not possible. The next part of the motion has the elbow joint extending which is called eccentric part. Then, the weight is lowered back to the start position. The reverse barbell curl in particular targets the biceps brachii which is positioned on the front part of your arm between the shoulder and the elbow. This muscle 's primary function is elbow flexion and forearm supination. The biceps also has two heads known as the long head and the short head.
Starting position
Stand erect, legs abducted to the width of the pelvis. Grip the bar with an overhand grip with phalanges in flexion and thumb in opposition and the wrist in full pronation. Keep your back in neutral position throughout the activity. Joint | Joint action | Muscle group | Muscle action type | Specific muscles | Elbow Joint | Extension | Elbow Joint Flexors | Eccentric | Biceps Brachii,
Brachialis,
Brachioradialis,
Pronator Teres |
Up phase
Breathe out and flex the elbow to bring bar/weight to the level of the chest with the wrist maintain in neutral position. Joint | Joint action | Muscle group | Muscle action type | Specific muscles | Elbow Joint | Flexion | Elbow Joint Extensors | Concentric | Biceps Brachii,
