skull crusher is an exercise for isolating the triceps. The
triceps brachii is composed of three heads. The
three heads of the triceps have separate attachments near
the shoulder but a singular attachment for each muscle just
below the elbow. Even
though body mechanics don’t allow for complete isolation
of any one given head, you can slightly shift the emphasis
from one head to another by using a variety of exercises and
angles. Good exercises for well defined and stong triceps
include dips, overhead press, skull crushers, chest press,
bench press, shoulder press and lateral raise.
