Pressing – Which muscles are involved?
Regardless of whether we like it or not, pressing the bars on a flat bench is the gold standard for assessing the total strength and efficiency of the upper part of our body. This is because few exercises engage such a large number of muscle groups. Therefore, before we delve into the technique, it is worth acquiring some anatomical knowledge and finding out which muscle groups are involved in this motion.
The main pectoral muscle, sometimes referred to as the larger breast muscle
Owing to its functions that encompass adduction and flexion of the arm, the main pectoral muscle is indisputably the most involved when carrying out the bench press exercise with a barbell.
The three-headed arm muscle, commonly referred to as the triceps
The triceps are the only muscles responsible for extending the elbow joint, which means they also play a crucial role in stiffening. It is also important to note that the side head and the long head, which are attached to the humerus, are primarily responsible for extending the elbow joint by stabilizing it at the end of the movement.
The muscles of the forearm
To be precise, it pertains to the anterior action of the forearm muscles, which displaces the wrist forward and carries out its rotational motion.
They are the rotator cuff muscles
This is a set of four muscles (supraspinatus, infraspinatus, teres minor, subscapularis) responsible for providing stability to the shoulder joint. It is critical that none of them cause a restriction in movement efficiency. These muscles aid in maintaining the head of the humerus in the proper location.
The two-headed muscle of the arm that also participates in lying press exercises
Yes, you have read that correctly... The biceps is also activated during the execution of exercises involving lying press movements... Because during the eccentric motion, when there is a bending in the elbow joint, the biceps functions as a stabilizer for our arm.
The widest muscle in the back
The widest muscle in the back assists in controlling the shoulders during pressing... Correct positioning and work in this region enables the pulling of the arms downwards, which decreases their strain and lessens the risk of rotator cuff injuries.
Quadriceps, also known as the four-headed thigh muscle
Proper execution of the incline bench exercise requires placing your feet on the ground and using your legs to maintain stability -- if you don't do this, you'll feel considerably less confident -- when our feet are firmly pressed against the floor, we automatically experience a strain on the quadriceps, which is beneficial because it provides additional support for the upper part of our body.
The most critical factor is the alignment
Despite appearances, achieving the correct position is not a trivial task. We must remember many elements, such as the proper positioning of the shoulder blades, wrists, breast and lumbar spine, legs, and feet. Any irregularity in these elements can lead to the loss of the correct position, which in turn can lead to weakening, lifting smaller weights, and providing less stimulation to our muscles. Regardless of whether we are modeling or building strength, we should always aim to lift ever-increasing weights, which translates to constant progress. When starting training, we must ensure that the stands on which the barbell rests are at the proper height, such that the exercising person can safely lift the barbell with retracted shoulder blades and extended arms. Proper alignment of the shoulder blades, i.e., retraction and depression, will help push the chest up and keep our arms in a safe and healthy position, reducing the risk of rotator cuff injuries. It is also essential to correctly align the lumbar spine, i.e., avoiding a maximum bridge (bend), while maintaining the natural curvature of the spine. This will, in turn, allow for a slight reduction in the range of motion and a safer execution of the movement for our shoulders. The final aspect of the correct position is the alignment of the feet, which will allow us to achieve a more stable and stronger position during exercise.
How to Correctly Perform the Bench Press Movement?
Now that we have the initial setup behind us, let's move on to the main aspect, which is the movement itself while lying on the bench and pressing the barbell. But I want to mention two elements that will help us maintain constant tension during pressing: breaking and tearing of the barbell during movement. These things will make it easier for us to activate the scapulae and set them in the correct position, and we'll also have better control over the barbell for the duration of the entire movement. When it comes to where we should guide the barbell, it is usually the upper chest, near the nipples. However, it's important to note that due to the different mobility of the lumbar spine, hips, and shoulder joints, the barbell's path of motion may look a little different for different people. Some will press almost straight, while others will have a larger arc. During the entire movement, three elements should remain in contact with the bench: head, thoracic spine, and gluteal muscles, which should remain tense throughout the entire movement. The barbell is lowered until it touches the upper chest, and the movement is ended by locking our elbows at the top. We don't exhale or end the movement with bent arms. Also, remember to guide the elbows ideally under the wrists throughout the entire movement.
Erroneous Conceptions
The most widespread misconception is not maintaining our hands in an extended position. Locking the elbow joints is not harmful to our joints. It is harmful to immediately exceed the range of motion. In such a scenario, pathologies may arise that are associated with movement outside the range of motion in the joints. By maintaining our hands in an extended position, the entire movement is safer and more controlled. This allows us to more easily synchronize our breathing and apply the Valsalva maneuver, which generates more force and creates a safer environment for our internal organs.
Summary of bench press bar squeezing techniques
As you can see, squeezing a bar on a bench requires taking into account a lot of elements to be effective and safe. We must take care of proper assistance, such as a training partner or stands that will allow us to secure ourselves. Above all, however, before attempting to squeeze the bar, we must master all aspects of the proper technique and eliminate any errors. Thanks to this, our pressing will become much better, which will allow for more effective shaping of the figure and increasing our strength achievements.
