Major muscle groups are important to the human body because they:

  • maintain proper posture,
  • help people move
  • and provide strength.

A Tour of the Major Muscle Groups

The Abdominal and Chest Area – contains three major muscle groups.

The abdominal area includes both abs and obliques.

  • The abs in the front protects several major organs including the stomach, kidneys and intestines. These muscles tense when a person laughs or coughs.
  • The obliques at the sides of the body help with twisting motions.
  • The chest contains pectoralis muscles, often called pecs. They help the body do push-ups and protect the heart and lungs.

Now that we’ve toured the mid-section, let’s take a look at the arms.

The Arms – contain three major muscle groups that help us lift heavy objects or carry things.

  • The deltoids in the body’s shoulders are most noticeable when you lift an object over your head or hold your arms out at your sides.
  • Biceps are the front arm muscles that people like to show off when asked how strong they are.
  • Triceps are the major muscles in the back of the arm. Now that we’ve learned the major muscles in the arms, let’s look at the legs.

The Legs – work hard to help us run, walk and lift.

  • The hamstrings at the back of the legs help us bend. They are stretched when we touch our toes or walk backwards.muscle groups
  • The quads are in the front of the upper leg. They help us stand from a sitting position.
  • The gastrocnemius, better known as the calf muscles, is in the lower leg.


That completes the tour of the leg’s major muscles, now let us learn move up to the rear end.

The Buttock – muscles are much more important than people realize. This major muscle group is called the gluteus maximus. We sit on these muscles every day. They also help us climb stairs and ride bikes.

This completes the tour of the body’s major muscle groups. Just remember abs, obliques, pecs, deltoids, biceps, triceps, hamstrings, quads, gastrocnemius and gluteus maximus. This saying may help you remember: “An Old Pig Doesn’t Bite Though He Quickly Gobbles Grapes.”
