Where is the Serratus Anterior Muscle or Boxer's Muscle Located and What is its Function?

Serratus Anterior Muscle lies between the lateral surface of the ribs and inside of the scapula. The main function of this muscle is to facilitate movements of the hands in horizontal direction like when pushing or pulling items. This muscle is also known by the name of Boxer's Muscle as this is the muscle used when punching during a boxing game. Any sort of weakness to this muscle ultimately affects the whole motion of the shoulder. Thus it is important to keep this muscle string and healthy. These muscles are sometimes also called wings of the body as they allow the hands to flap like wings. They also help in protecting ourselves from any harmful insect or anything thrown at us. These muscles also help in breathing. These muscles stem from the ribs and go into the scapula. These muscles stabilize the shoulder blades and when these muscles are flexed they help the ribs to expand and thus help with breathing.

Now, try and push the body up away from the ground such that your body weight is entirely on your palms. This will stretch the serratus anterior muscle. At first you may not be able to move much but with continuous practice the distance will gradually increase and the stretch will also increase and with time you will be able to move the feet in the air such that the torso is suspended in the air.

Now, press the back into the backrest and hold the dumbbells with both hands and keep them at a shoulder's width. Lower the dumbbells to the chest and then take them up vertically away from the chest.

These exercises also help with smooth expansion of the ribcage thus facilitating comfortable breathing. To do this exercise, lie on an exercise bench with the knees bent and the feet flat. Hold dumbbells on both hands. Start with the arms extended vertically above the chest. Now, slowly lower the dumbbell to move it behind your head just slightly bending the elbows. Now, contract the back and chest and come back to the normal position.

Hold the ball and allow it to fall gently on your chest with your hands acting as a resistance thus controlling the speed with which the ball falls. Once reached, push the ball again to the trainer and repeat the same exercise.
