Arms—Biceps and Triceps
To some people the biceps are the symbol of strength. Every-
body can relate to arms. Arms are one of the most impressive
parts of the body, the part everybody wants to see. When some-
body says, "Show me your muscles," you don't show your calves.
You automatically lift up your arm and flex your bicep. A lot of
attention should be put into arms so they look good.
The upper arm is made up of two muscle groups—the biceps
and the triceps. As the prefix "bi" implies, the bicep has two
parts. The short head arises from a tendon attached to the corocoid
process of the scapula and inserts into the upper portion of the
radius bone of the forearm. It aids in the flexion of the upper
arm, shoulder and forearm. The long head of the biceps origi-
nates from the supra glenoid tuberosity of the upper arm bone
and inserts in a common tendon sheath with the short head into
the forearm. Its major function is the flexion of the forearm. The
tricep is composed of three muscles with a common tendonous
attachment—hence the name triceps. The long head arises from
a tendon on the scapula; the lateral from the posterior surface of
the upper arm (humerus) bone; and the medial head has its ori-
gin in an area just below that of the lateral head. All three insert
into a single tendon attached to the forearm. The action of the
triceps is to extend the forearm, with the long head also aiding in
bringing the arm closer to the body from a lateral position.

BARBELL
CURL—STANDING—Grip
the bar shoulder-width,
letting it rest against your thighs. Curl the bar up with only your
forearms. Your upper arm should remain in the same position
throughout the exercise. It's important that you don't borrow
from your other muscles. Flex your biceps firmly at the top of the
curl. Lower the bar slowly and repeat.
Use the add-weight rep system for five sets of 8, 8, 6, 6, 6 reps.
