Human Body Muscle Groups – Know Your Target Area

We are going to start talking about different muscle groups. I feel it is important to give you information on the human body muscle groups. This will be a very general topic, but very important to touch upon. I will tell you about the major muscle groups and the minor muscle groups. I also, will break this down even further to upper and lower body muscle groups. This alone will help you narrow down the choices for finding your target muscle.

A Major Muscle Group

Muscle Diagram

A major muscle group is the primary muscles that tend to do the moving in that specified area. When you decide to exercise a certain area or major muscle group. You have chosen a fabulous way of exercising or starting a workout system for that target area. Every exercise will work one of these major muscle groups. There are several schools of thought regarding workout methods. The full body workout versus the split routine. I personally like the full body workout, but I would recommend doing what ever works for you.

A Minor Muscle Group

A Minor muscle is just a small muscle that helps those bigger muscles. The bigger muscles cannot move by themselves, the major muscles groups all need these smaller muscles. For this reason, they are called “synergists” muscles. The muscle count in the human body is well over 600 muscles. Many of our body muscles are small or minor muscles, but as with almost everything their are some exceptions.

The Upper Body Muscle Groups

Most of the human body muscle groups fall into this area (the upper body). This will reveal itself as we make a list of the major muscle groups here in the upper body.

  1. The Chest Muscles (Pectoralis Major. Pectoralis Minor)
  2. The Shoulder Muscles (Deltoid, Anterior Head, Middle Head, and Posterior Head)
  3. The Back Muscles (Teres Major, Teres Minor, Trapezius, Rhomboid Major, Infraspinatus, Latissimus Dorsi, Erector Spinae (Deep), and the Thoracolumbar Fascia)
  4. The Biceps (Brachialis, Biceps Brachii (Long and Short Head))
  5. The Triceps (Triceps Brachii (Lateral Head and Long Head), Medial Head)
  6. The Forearms (Brachioradialis, Extensor Pollicis Brevis, Extensor Carpi Ulnaris, Flexor Carpi Ulnaris, Abductor Pollicis Longus, Palmaris Longus, Extensor Pollicis Longus, and the Flexor Carpi Radialis)
  7. The Abdominals (External Obliques, Serratus Anterior, Rectus Abdominals, and the Tendinous Inscriptions
  8. The Glutes (Gluteus Medius and the Gluteus Maximus)

The Lower Body Muscle Groups

There are just a few a muscle groups in the lower body, but they are pretty massive. I will list them for you.

  1. The Hamstring Muscle (Iliotibial Band, Biceps Femoris, Adductor Magnus, Semitendinosus, Gracilis, and the Semimembranosus)
  2. The Thigh Muscle (Sartorius, Pectineus, Adductor Longus, and the Tensor Fasciae Latae)
  3. The calf  Muscle (Gastrocnemius, Soleus, Tibialis Anterior, Peroneus Longus, and the Extensor Digitorum Longus)

Exercise With A Target

Armed with this information, I know you can exercise with a target a little easier than you could before. I gave you the major muscle groups of the body. The minor muscle groups of the body, with a somewhat detailed overview of the upper and lower body muscle groups. I hope this information can help you.


  1. Great information! It is easy to forget that targeting specific muscle groups in exercise is so good for building strength and health. Thanks for this reminder.
