We’ve been assembling a list of gym terms, gym speak and other gym related words and expressions for a few years now. The list is far from complete but we add a few more things weekly. If there is a term, or miuscle or any other form of lingo that makes you feel awkward or confused, then this is a good place to look for what it actually means.
Abdominal MusclesThe muscles of the midsection: rectus abdominis, oblique (external, internal, and transverse), and intercostal. The abdominals help flex the torso forward and from side to side, twist the torso in relation to the hips, depress the rib cage, and stabilize the midsection during squats, deadlifts, and overhead lifts.Abdominal TypeSee Endomorph, Ectomorph or MesomorphAbductionMovement of the straight legs, accomplished by contraction of the leg abductor muscles (the sarorius, primarily), from a fully abducted position back to one in which the legs are again pressed together.Adductor Brevis MuscleAdductor Brevis is the smallest and shortest of the three short adductor muscles. It originates on the pelvis and inserts into the thigh bone and adducts inwards and flexes the hip out forwards. It is most commonly injured in a groin strain.Adductor Longus MuscleAdductor Longus is the middle of the three short adductor muscles. It adducts the hip inwards and assists in hip flexion or moving the leg forwards. Originating on the ramus of the pelvis and inserts into the femur or thigh bone.Adductor Magnus MuscleAdductor Magnus is the largest groin muscle and is one of the two long adductor muscles (gracilis is the other). It is usually described as having two parts, hamstring and adductor parts. It adducts, flexes and internally rotates the hip.ActinA protein found in muscle fibers that acts with myosin to bring about contraction and relaxation.AdenosineA compound derived from nucleic acid, composed of adenine and a sugar, D - ribose. Adenosine is the major molecular component of the nucleotides adnosine monophosphate, adenosine diphosphate, and adenosine triphosphate and of the nucleic acids deoxyribonucleic acid and ribonucleic acid.Adenosine DiphosphateA product of the hydrolysis of adenosine triphosphate.Adenosine monophosphate (AMP)An ester, composed of adenine, D - ribose, and phosphoric acid, that affects energy release in work done by a mucle.Adenosine PhosphateA compound consisting of the nucleotide adenosine attached through its ribose group to one, two, or three phosphoric acid molecules. Kinds of adenosine phosphate, all of which are inter convertible, are adenosine diphosphate, adenosine monophosphate, and adenosine triphosphate.Adenosine Triphosphatase (ATPase)An enzyme in skeletal muscle that catalyzes the hydrolysis of adenosine triphosphate to adenosine diphosphate and inorganic phosphate. Among various enzymes in this group associated with cell membranes and intracellular structures, mitochondrial ATPase is involved in obtaining energy for cellular metabolism, and myosin ATPase is involved in muscle contraction.Adenosine Triphosphate (ATP)A compound consisting of the nucleotide adenosine attached through its ribose group to three phosphoric acid molecules. It serves to store energy in muscles, which is released when it is hydrolyzed to adenosine diphosphate.AdrenalPertains to the adrenal or suparenal glands located atop the kidneys.Adrenal CortexThe outer and larger section of the adrenal gland, which produces mineralocorticoids, androgens, and glucocorticoids - hormones essential to homeostasis.Adrenal GlandEither of two secretory organs located on top of the kidneys and surrounded by the protective fat capsule of the kidneys. Each consists of two parts having independent functions: the cortex and the medulla. The adrenal cortex, in response to adrenocorticotropic hormone secreted by the anterior pituitary, secretes cortisol and androgens. Adrenal androgens serve as precursors that are converted by the liver to testosterone and estrogens. Renin from the kidney controls adrenal corticol production of aldosterone. The adrenal medulla manufactures the catecholamines, epinephrine and norepinephrine.Adrenal MedullaThe inner portion of the adrenal gland. Adrenal medulla cells secrete epinephrine and norepinephrine.Advanced TraineeAn individual with at least one year of steady, systematic resistance training experience.Aerobic ExerciseProlonged, moderate - intensity work that uses up oxygen at or below the level at which your cardiorespiratory system can replenish oxygen in the working muscles. Aerobic literally means "with oxygen", and the only type of exercise that burns body fat to meet its energy needs. Bodybuilders engage in aerobic workouts to develop additional heart / lung fitness, as well as to burn off excess body fat to achieve peak contest muscularity. Common aerobic activities include running, cycling, stair climbing, swimming, dancing, and walking. Depending on how vigorously you play them, most racket sports can also be aerobic exercise.Amino AcidsOften called the "building blocks of life," amino acids are subunits that join together in sequences to form protein. Amino acids are named as such because they contain both an acid and an amine chemical side unit.AnabolicChemical reaction in the body where smaller subunits are combined to form larger units. As an example, amino acids are joined together to form long polypeptide chains which in turn join to form strands of protein.Anabolic SteroidsPrescription drugs that mimic male hormones, but without most of the androgenic side effects of actual testosterone. Many bodybuilders use these dangerous drugs to help increase muscle mass and strength, even though possession of them is now a felony in most states.AnabolismConstructive metabolism characterized by the conversion of simpler compounds into more complex ones.Anaerobic ExerciseExercise of much higher intensity than aerobic work, which uses up oxygen more quickly than the body can replenish it in the working muscles. Anaerobic exercise eventually builds up a significant oxygen debt that forces an athlete to terminate the exercise session rather quickly. Anaerobic exercise (the kind of exercise to which bodybuilding training belongs) burns up glycogen (muscle sugar) to supply its energy needs. Fast sprinting is a typical anaerobic form of exercise.Anconeus MuscleThe Anconeus works alongside Triceps Brachii in extending the elbow. It also acts to pull the synovial membrane out of the way of the olecranon process when the elbow is extending.AndrogenicTerm used to describe one of the two primary categories of effects produced by such agents as anabolic steroids and testosterone. Androgenic effects include acne, increased facial hair, and the development of secondary sexual characteristics.Ankle CollarThe ankle collar is a wide, leather ankle bracelet which you clip to pulleys to perform exercises such as left lifts, and leg curls. It is largely used for leg exercises.AnorexiaAnorexia is a lack or loss of appetite, resulting in the inability to eat. Anorexia may result from poorly prepared or unattractive food or surroundings, unfavorable company, or various physical and psychological cause.Anorexia NervosaA disorder characterized by a prolonged refusal to eat, resulting in emaciation, amenorrhea, emotional disturbance concerning body image, and an abnormal fear of becoming obese. The condition is seen primarily in adolescents, predominantly in girls, and is usually associated with emotional stress or conflict, such as anxiety, irritation, anger and fear, which may accompany a major change in the person's life. Treatment consists of measures to improve nourishment, followed by therapy to overcome the underlying emotional conflicts.AnorexiantA drug or other agent that suppresses the appetite, such as amphetamine, phentermine, diethylpropion, fenfluramine, or dexfluramine.AntagonisticPharmacological term used to describe a drug that blocks or shuts down a receptor, thus reducing or terminating a given biochemical response.Antagonistic MuscleOne with the polar - opposite function of a primary muscle. As examples, the leg biceps are antagonistic to the quadriceps, the triceps antagonistic to the biceps, and forearm flexors antagonistic to the forearm extensors. Antagonistic muscle groups are frequently supersetted in a high - intensity workout.AnteriorUsed to describe the position of a structure when it is in front of another comparable structure, such as the anterior (or front) deltoid head.Antidiuretic Hormone (ADH)Hormone produced by the posterior pituitary responsible for fluid and mineral conservation in the mammalian body. Bodybuilders often take ADH blockers to promote water loss in the days leading up to a bodybuilding competition.AntioxidantsGroup of substances reputed to neutralize harmful free radicals produced during cellular respiration.Arm BlasterUsing an arm blaster is a very strict way to perform barbell (or E - Z bar) curls. Using an arm blaster promotes a similar effect as using a preacher bench. No elbow movement at all, and strict isolation of the biceps.ATPSee Adenosine Triphosphate (ATP)AtrophyShrinking of the muscles caused by catabolism. The reverse of Hypertrophy
