The term biceps refers, in its most general meaning, to something that has two ends or two heads . The concept is usually used in the field of anatomy to name a paired muscle that, at its upper end, has two insertions or sectors .
The biceps brachii muscle is located in the arm, covering the brachialis anterior and coracobrachialis muscles. In its upper sector it has a long portion (which descends through the humerus) and a short portion (originated by a tendon that it shares with the coracobrachialis muscle).
Hypertrophy of the biceps brachii
The biceps brachii, vascularized by the bicipital arteries, is innervated by a branch of the musculocutaneous nerve. This muscle allows the arm to move, allowing - along with other muscles - the flexion of the elbow. In other words, the biceps brachii extends from the upper sector of the radius to the shoulder blade. When it contracts, it allows the forearm to bend over the arm.
It is common for people to perform specific physical exercises for the development of the biceps due to their hypertrophy capacity. Repetition of certain movements and lifting weight cause the biceps to increase in size.
thigh muscles
The biceps femoris muscle , on the other hand, is located in the thigh. Also known as the biceps femoris , it is located in the posterolateral region of this part of the leg and has a short portion (femoral) and a long portion (ischial).
When the biceps femoris contracts, it causes the leg to bend over the thigh. Together with the semitendinosus and semimembranosus muscles they make up the group known as the hamstring muscles .
How to exercise the biceps
People who work their bodies to tone them and achieve the best possible condition use this term daily, since working the biceps is one of the most important objectives of their exercises. Although there are a large number of different routines that fit all needs and allow you to achieve different goals, one of the points in common is the use of dumbbells.
Through the use of dumbbells, which some simply call dumbbells , it is possible to work the lower, external and internal biceps. One of the most common exercises consists of flexing the biceps alternately, and the basic steps are as follows:
* hold a weight in each hand, with palms facing forward;
* raise one of the dumbbells by bending the elbow, pause briefly and then bring the arm back to its resting position, so that the dumbbell descends;
* repeat until we reach the number we have set and then do the same with the other arm.
There is another exercise, which proposes alternating biceps flexes ; Although it is very similar to the previous one, it is important to know its steps in detail:
* the initial posture is almost the same, although the palms of the hands should point towards each other;
* we raise one dumbbell to shoulder height , pause briefly and then lower it, at the same time we begin to raise the other;
* We must avoid any movement of the trunk that could "help" the arms to lighten the load.
The next exercise is a natural evolution of the latter, and is called inner bicep curls . The initial position is identical to the previous one, so the first difference is seen in the lifting movement, since in this case we must flex both arms simultaneously, make them reach shoulder height, let them rest briefly and Extend them to return to rest, before repeating several times. In all cases it is important not to lift an excessive load or continue working our muscles when we feel exhausted.
