Hammer curls are a perfect low - intensity exercise for building of the brachialis, which is an important muscle
in the upper arm that's activated during isometric
elbow flexion.
Keep plenty of
flexion in your
elbow.
Furthermore, the short head appears to be more active
in the latter part of an arm curl (i.e. greater
elbow flexion) while the long head is more active
in the early phase.
EMG studies of the long head of the biceps brachii show that muscle fibers
in the lateral portion of the muscle are recruited for
elbow flexion, fibers
in the medial aspect are recruited for supination, and centrally located fibers are recruited for non-linear combinations of
flexion and supination.
They're called hip flexors because they create
flexion in the hip, which is the technical term for a bending movement around a joint
in a limb (such as the knee or
elbow) that decreases the angle between the bones of the limb at the joint.

In the next phase, you're going to start at the top and lower the bar to just above the sticking point (which is usually 90 degrees of
elbow flexion).
In the sagittal plane, the short and long head of the biceps perform
elbow flexion and displays its greatest force producing potential with the
elbow flexed at 90 degrees.
Upper body pressing exercises typically include
elbow extension
in addition to horizontal
flexion — i.e. bench pressing — or shoulder
flexion — i.e. shoulder pressing.
This is likely due to the vertical displacement of the bar at the start of the sticking point and resulting shoulder abduction and
elbow flexion angles, and therefore, the sticking region of unsuccessful attempts starts earlier
in the ascending phase compared with successful lifts.
Nevertheless, it seems that the moment arm length of the triceps decreases gradually
in a linear fashion as
elbow flexion increases.
As the
elbow moves from 30 degrees of
flexion (semi-straight) to 110 degrees (nearly completely flexed) the moment arm length decreased
in a linear fashion.
In support of this, Sugisaki et al. (2010) reported that the triceps displayed a peak moment arm (length = 23.9 mm) at 30 degrees of
elbow flexion and a minimum moment arm (length = 17.4 mm) at 110 degrees of
elbow flexion.
The
elbow joint consists of three bones (humerus = upper arm bone, radius and ulna = forearm bones) that fit together perfectly to allow
flexion and extension motion
in the front leg.
The
elbow is formed
in such a way as to allow
flexion, extension and rotation of the limb.
