![]() Because your biceps derive a fair amount of work during your back training, minimal direct training may be needed. How much emphasis depends on muscle insertions, exercise form and neural excitatory thresholds. They overlap with pulling exercises, such as chins, pulldowns, lat rows and upright rows. ![]() While the big muscles of the body (hip flexors, quadriceps, hamstrings, pecs, lats, rhomboids, traps, spinal erectors) drive powerful action, the muscles of the arm (biceps, triceps and forearms) transfer that force into your opponent, the ball or the bat, racquet, club or instrument of your particular sport.īiceps derive a great deal of stimulation from their use as a secondary mover. ![]() The muscles of the arms have a unique function in sports movement. The coracobrachialis lies under the biceps but, since it does not cross the elbow joint (it assists the shoulder and back muscles with rowing-type movements), it is not considered part of the biceps (elbow flexor) group. The brachioradialis inserts on the other bone in the forearm on the “thumb side” (the lateral surface of the distal radius, at the styloid process), partway between the elbow and wrist) and originates low on the upper arm bone, near the outer elbow (the distal section of the lateral condyloid ridge of the humerus). A peaked shape to the biceps comes from placement of the tendons of the two biceps heads. If your arms are well-developed and you possess low bodyfat levels, you will be able to see the split between the two heads of the biceps. The medial (short or “inner”) biceps head originates on the coracoid process of the scapula (upper shoulder blade) and the upper lip of the glenoid fossa (the cartilage-lined depression of bone that the humerus is placed in the shoulder joint). The lateral (“outer” or long) head originates on your shoulder blade (on the supraglenoid tubercle, above the glenoid fossa) and the tendon crosses inside the head of the humerus to emerge at the upper arm. Both heads share a common insertion on the tuberosity of the radius (you can feel this thick tendon just beneath the skin on the inside of your elbow). The tendons that attach muscles are referred to as the origin (the tendon closest to spine) and an insertion (the tendon of attachment furthest down the arm).Īs its name suggests, the biceps is a two-headed muscle which crosses both the elbow and shoulder joints. There are two bones in the forearm, the radius (the shorter bone on the “pinky side” of your forearm) and the ulna (the main stabilizing bone of the forearm on the “thumb side”). The major bone of the upper arm is the humerus (which gives us the term funny bone). Because they tend to work together, the biceps group also includes the brachialis, brachioradialis and pronator teres muscles. When we speak of the biceps we generally mean more than just the biceps brachii. The new physical female ideal is not just lean, but possesses a body, and in particular, arms with muscularity and definition.Īn understanding of the structures and actions of the muscles of the upper arm are important when designing your biceps training program. Hollywood starlets Linda Hamilton and Angela Basset sported gun-emphasizing tanktops and impressed audiences with their lean, strong looking arms. In women, shapely muscular arms have recently come in vogue. In part, because they are displayed nine months out of the year (during short-sleeve weather) and are often the first muscles in which we notice growth during puberty (either in ourselves or in our more genetically-gifted classmates). Properly developed biceps are important on stage because they balance a competitor’s physique.”įor men, arms have always been a marker of masculinity. Underdeveloped biceps will be overshadowed by the anterior delts. “A champion bodybuilder should display balanced development of the entire musculature, biceps included,” says NPC Kentucky class winner Steve Weingarten. “And there are very few poses that aren't enhanced by a pair of billowing, peaked biceps!” The wow factor of big, shapely arms cannot be overlooked, whether on the beach, on the bodybuilding stage or straining under a well-tailored suit.Īccording to Ray Binkowski, multiple bodybuilding class title holder, “Take the front and rear double bicep poses. Overly developed biceps will overshadow the anterior delts. They tend to respond well to training for 90% of us, due to their strong neural pathways and above average blood supply, which almost guarantee muscle pumps. In bodybuilding, biceps are, without a doubt, the favorite bodypart for most of us to train.
