Dumbbell Chest Fly

Dumbbell Chest Fly

Talking about isolation exercises, the dumbbell chest fly on a flat bench is key to developing your pectoral muscles. It works mainly the pectoralis minor.

Sit on a flat bench with a dumbbell on each hand resting on top of your thighs. The palms of your hand will be facing each other.

Using your thighs to help raise the dumbbells, lift the dumbbells one at a time so you can hold them in front of you at shoulder width with the palms of your hands facing each other.

Lie on your back with your feet placed firmly on the floor or the bench itself so that you can keep your spine in a neutral position. Pull your shoulder blades down and back so that they make firm contact with the bench. Your head, shoulders, and butt should make contact with the bench throughout the exercise.

Raise the dumbbells up like you’re pressing them, but stop and hold just before you lock out.

Inhale and with a slight bend on your elbows in order to prevent stress at the biceps tendon, lower your arms out at both sides in a wide arc until you feel a stretch on your chest.

Exhale and return your arms up you squeeze your chest muscles. Make sure to use the same arc of motion used to lower the weights.

Hold for a moment at the contracted position and repeat the movement until you complete the set.

Standard Push-Up

Standard Push-Up

One of the most fundamental exercises on earth. Treat the push-up with respect, and it’ll be a friend for life :)

Come to plank position. Engage the abdominals and pull the shoulder blades down your back. Your head should be aligned with your spine. Your feet are together.

Inhale and slowly bend the elbows, lowering your body toward the floor. Keep the torso engaged and the head aligned with your spine. Do not allow your lower back or ribcage to sag or your hips to hike upward.

To maintain stability also, engage your butt (glutes) and thigh (quadriceps) muscles. Try to lower yourself until your chest or chin touch the mat or floor.
Exhale and press upward through your arms, straightening the elbows. Imagine pushing the floor away from you.

We usually call our pectoral muscles “pecs”.  The first thing we need to know is that pectoral muscles are a group of muscles.

The pectoralis major makes up the bulk of the chest muscles in the male and lies under the breast in the female.


  1. Medial 1/3 of the clavicle.
  2. Anterior aspect of manubrium & length of the body of the sternum.
  3. Cartilaginous attachments of upper 6 ribs.
  4. External oblique’s aponeurosis.


  1. Lateral lip of bicipital groove to the crest of the greater tubercle.
  2. Clavicular fibers insert more distally; sternal fibers more proximally.

It performs four actions:

  1. Flexion of the humerus, as in throwing a ball side-arm, and in lifting a child.
  2. Adducts the humerus, as when flapping the arms.
  3. Rotates the humerus medially, as occurs when arm-wrestling.
  4. Keeps the arm attached to the trunk of the body.
Pain and symptoms associated with the Pectoralis Major muscle
– Chest pain
– Pain in the front of the shoulder
– Pain in the inner arm, inner elbow traveling down to the into the middle and ring fingers
– Breast pain
– Upper back pain between and around the shoulder blades
– Pain when trying to reach behind the body
– Rounded shoulder posture
– Contributor to forward head posture
Activities that cause pain and symptoms of the pectoralis major muscle
– Lifting heavy objects
– Working with your arms out in front of you (computer)
– Driving and horseback riding: both require you to hold your arms up and in front of your body
– Keeping your shoulders rolled forward or pulled up
– Slouching
– Carrying a heavy purse or backpack on one shoulder
– Large breasts

The pectoralis minor is a thin, triangular muscle, situated at the upper part of the chest, beneath the pectoralis major. The pectoralis minor depresses the point of the shoulder, drawing the scapula inferior, towards the thorax, and throwing its inferior angle posteriorly.


The outer surface of ribs 2-5 or 3-5 or 6.


Medial aspect of the coracoid process of the scapula.

Pain and symptoms associated with the Pectoralis Minor muscle
– Chest pain
– Burning and stabbing like pain in the pectoral (chest) area
– Pain in the front of the shoulder
– Pain in the inner arm, inner elbow traveling down to the into the fourth and fifth fingers
– Numbness in the inside of the forearm, wrist, hand and fingers
– Difficulty reaching forward and up
– Pain in the upper back between the shoulder blades
– Pain when reaching behind the body
– Rounded shoulder posture
Activities that cause pectoralis minor pain and symptoms
– Lifting heavy objects
– Pushing things away from the body
– Push ups
– Lifting objects with arms straight in front of the body
– Working with your arms out in front of you (computer)
– Keeping your shoulders rolled forward or pulled up
– Carrying a heavy purse or backpack on one shoulder
– Hyperventilation, difficulty breathing
– Chronic cough
– Under-wire bras
– Large breasts
– Whiplash

The subclavius is a small triangular muscle, placed between the clavicle and the first rib. Along with the pectoralis major and pectoralis minor muscles, the subclavius muscle makes up the anterior wall of the axilla.



First rib about the junction of bone and cartilage.


The lower surface of the clavicle.

The subclavius depresses the shoulder, carrying it downward and forward. It draws the clavicle inferiorly as well as anteriorly. Also, protects the underlying brachial plexus and subclavian vessels from a broken clavicle (the most frequently broken long bone).

Pain and symptoms associated with the subclavius muscle

– Pain below the collarbone
– Pain in the upper arm
– Sends pain down the forearm into the thumb, forefinger, and middle finger
– A reliable indicator of subclavius muscle dysfunction is a pain on the outside of the upper arm that skips over the elbow then extends into the forearm. Pain can also extend to the thumb, index, and middle finger while skipping over the wrist.
– The muscle can tighten restricting circulation to the arm and hand causing tingling and numbness

Activities that cause subclavius pain and symptoms

– Lifting heavy objects
– Working with your arms out in front of you (computer, driving)
– Keeping your shoulders rolled forward
– Sleeping on your side with your arm above your head
– Broken clavicle

The serratus anterior is found more laterally in the chest and, forms the medial wall of the axilla.

Serratus anterior


Fleshy slips from the outer surface of upper 8 or 9 ribs.


The costal aspect of medial margin of the scapula.

The main action of the serratus anterior is to rotate the scapula, allowing the arm to be raised over 90 degrees. It also holds the scapula against the rib cage – this is particularly useful when upper limb reaches anteriorly (e.g punching).

Pain and symptoms associated with the Serratus anterior

– Pain on the side of the chest toward the middle of the ribcage
– Pain down the arm to the fourth and fifth fingers
– Pain below the shoulder blade
– Difficulty breathing
– Inability to take a deep breath
– Sharp pain in the side (side stitch)
– Pain and difficulty reaching behind the body
– Pain and difficulty when pulling shoulders back
– Sensitivity in and around the area of the breast

Activities that cause serratus anterior pain and symptoms

– Swimming
– Tennis
– Chin ups, Push ups
– Weightlifting
– Gymnastics
– Hyperventilation
– Severe coughing
