THE MUSCLES OF THE UPPER LEG
The quadriceps are the muscles at the front of the thigh which act as ex-
tensors of the leg. The four muscles involved are the rectus femoris, the
vastus intermedius (these two muscles making up the central V-shape de-
lineation of the middle front thigh), the vastus medialis of the inner thigh,
and the vastus lateralis of the outer thigh.

Other important muscles of the upper leg include the tensor fasciae
latae, coming down from the hip to the outer thigh; and the sartorius,
the longest muscle in the body, which weaves diagonally across the front
of the thigh.
The muscles of the upper leg are the largest and most powerful in the en-
tire body. There are few movements in sports that do not involve intense
leg effort. A baseball player, golfer, discus thrower, shot-putter, and boxer

all begin their respective movements with a powerful leg drive. In
weightlifting, most power moves like Power Cleans, Clean and Press, and
Deadlifts involve a lot of leg effort, as do the lifts used in Olympic
However, there is no sport in which thigh development is as important
as in bodybuilding. While contest judges have the shoulders, chest, arms,
back, and abs to occupy their attention above a bodybuilder's waist, when
they look at the lower body the single most compelling visual element is
quadriceps and the hamstrings. Thighs are the most mas-
sive muscle group in the body and proportionately constitute almost half
of your physique.
