Muscles. Listed below are the muscles we will learn: For this section of the Fitness Unit, we are going to learn the major muscles: Their location, function and specific exercises that help in their development. Listed below are the muscles we will learn: Front view: Back view: -Deltoids -Trapezius -Biceps Brachii -Latissimus Dorsi -Pectoralis Major -Triceps Brachii -Rectus Abdominus -Hamstrings -Quadriceps Group -Gastrocnemius -Gluteus Maximus

Muscles (front) Deltoids. Pectoralis Major. Biceps Brachii Rectus Abdominus. Quadriceps.

Deltoid. Definition: The Deltoid allows the shoulder to move in many different directions. Function: The Deltoid has three movements/functions. The Deltoid flexes (decreased angle of the joint) , abducts (makes arm move away from center of the body) and extends (increased angle of the join) the arm. Exercises: -Front Dumbbell raises. -Seated lateral raises. -Alternate dumbbell press -Military press

Muscles (Back) Trapezius. Triceps Brachii. Latissimus Dorsi. Gluteus Maximus. Hamstring. Gastrocnemius.

Trapezius Function: The Trapezius raises and lowers the shoulders and extends the neck. Location: The Trapezius or “Traps”, go from the base of the skull, down the vertebral column to the scapula. Exercises: -Shoulder Shrug -Upright Row -Military Press -Dumbbell Press

Triceps Brachii Function: The “Triceps Brachii” role is to extend the elbow. Location: The “Triceps Brachii” is on the back of the upper arm. It attaches on the scapula and down to the humerus. Exercises: - Tricep Press Down. -Lying or StandingTriceps Extension -Overhead Press
