3. Types of Muscles • Voluntary-Those muscles that can be moved by our thoughts and actions. • Involuntary-Reflex action is made without our thought. • Cardiac-The muscle of the heart Ex: This muscle is constantly working automatically without thought or reflex being needed. Without this cardiac functioning muscle, we die!

4. Muscle Anatomy • Gastrocnemius- the largest muscle in the calf of the leg, the action of which extends the foot, raises the heel, and assists in bending the knee. • Basic exercise: toe/calf raises

5. Muscle Anatomy • Biceps- The biceps is a muscle on the front part of the upper arm. • Basic exercise: Arm curls • Triceps- a muscle having three heads or points of origin, especially the muscle on the back of the arm • Basic Exercise: arm extensions

6. Muscle Anatomy • LatissimusDorsi- a broad, flat muscle on each side of the mid-back, the action of which draws the arm backward and downward and rotates the front of the arm toward the body. • Basic exercise: lat pull down
