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.
Eccentric ContractionWhen a given resistance overcomes the muscle tension so that the muscle actually lengthens the muscle is said to be in eccentric contraction. Although the contracting muscle develops tension, it is overpowered by resistance. When you slowly lower a curled weight from the shoulder, the biceps muscle contracts eccentrically. If the biceps was relaxed, gravity would extend the elbow joint and lower the weight with considerable speed. Slowing the movement against resistance provides an additional muscle - developing factor.EctomorphThe ectomorph is the extreme somatotype. An ectomorph is characterized smalls bones and very little muscle mass. An ectomorph will have a very steep angle in his or her thorax, and the ribs are closer together. Ectomorphs are generally better endurance athletes than bodybuilders by nature, and may excel in cross country running. That is not to say an ectomorph cannot bodybuild. It is very possible to achieve great gains in mass and strength regardless of being an ectomorph.ElectrolytesCharged atoms called ions which help regulate the body's various metabolic systems. Athletes regularly consume drinks enriched with electrolytes such as potassium, calcium, and sodium to replace those lost in sweat.ElectrostimulationMuscle - stimulation technique involving the use of low voltage electric current. Although of limited use in physiotherapy, the technique's merits as an ergogenic aid are questionable.Endocrine SystemThe network of ductless glands and other structures that elaborate and secrete hormones directly into the bloodstream, affecting the function of specific target organs. Glands of the endocrine system include the thyroid and the parathyroid, the anterior pituitary, and the posterior pituitary, the pancreas, the suprarenal glands, and the gonads.EndomorphThe endomorph is characterized by a round physique, carrying extra body fat. The endomorph is has a large bone structure, and has a good portion of muscle mass. The endomorph has a wide thorax (rib cage), which makes a large angle with his ribs. It is sometimes more difficult for an endomorph to keep weight down, but it is entirely possible that an endomorph make great gains with his or her training to the point where it may even seem as though his or her body type has completely changed!EnduranceStamina, or the ability to continue voluntary muscle contractions for a sustained period of time.Erector Spinae MuscleThe erector spinae (sometimes known as sacrospinalis) is often described as a group of different muscles called iliocostalis, longissimus and spinalis.Essential Amino AcidsThe nine amino acids that cannot be manufactured by the body and must be consumed in the diet.EstrogenOne of the two primary sex hormones of the female body. The other one being progesterone. In males, excess testosterone is converted to estrogen often leading to the condition of gynecomastia.EversionTurning the bottom of the foot toward the outside. For calf raises this hits the outer head of the gastrocnemius.ExerciseEach individual movement (example, a seated pulley row, barbell curl, or seated calf raise) that you perform in your bodybuilding workouts.Extensor Carpi Radialis Brevis MuscleThe extensor carpi radialis brevis muscle extends and abducts the wrist and is a weak extensor of the elbow.Extensor Carpi Radialis Longus MuscleThe extensor carpi radialis longus muscle extends and abducts the wrist and is a weak extensor of the elbow.Extensor Carpi Ulnaris MuscleExtensor carpi ulnaris is located on the back (dorsum) of the forearm. It extends and adducts the wrist and weakly extends the elbow.Extensor Digitorum Longus MuscleExtensor digitorum longus (often shortened to EDL) is found in the front of the lower leg, in the outer more muscle bound compartment.Extensor Hallucis Longus MuscleThe extensor hallucis longus is the only muscle responaible for extending (pulling back) the big toe, dorsi flexes the ankle and weakly inverts the foot.External Obliques MuscleThe obliques wrap around the trunk on each side to form our waists and join to the linea alba, a band of connective tissue running down the front of the abdomen.E - Z Curl BarA special type of barbell used in many arm exercises, but particularly for standing E - Z bar curls wherein it removes from your wrists strain that might be present when doing the movement with a straight bar. An E - Z curl bar is occasionally called a cambered curling bar.FailureSee Temporary Muscular Failure (TMF)Fast-Twitch Muscle FibersWhite muscle fibers which contract quickly and powerfully, but not with great endurance. Fast - twitch fibers are developed by heavy, low - rep, explosive weight training.FatA high energy molecule which provides the body with long - term fuel reserves. Fat also serves as a precursor for many hormones and offers the body varying degrees of insulation and cushioning.FDAUnited States Food and Drug Administration.FlexibilityA suppleness of joints, muscle masses, and connective tissues which lets you move your limbs over an exaggerated range of motion. A valuable quality in bodybuilding training, it promotes optimum physical development. Flexibility can only be attained through systematic stretching training, which should form a cornerstone of your overall bodybuilding philosophy.Flexor Carpi Radialis MuscleThe flexor carpi radialis muscle flexes and abducts the wrist and is a weak flexor of the elbow.Flexor Carpi Ulnaris MuscleThe flexor carpi ulnaris muscle flexes and adducts the wrist as well as being a weak flexer of the elbow.Flexor Digitorum Longus MuscleFlexor Digitorum Longus causes the toes to grip and mold to the floors surface which is vital in maintaining balance on rough surfaces.Flexor Digitorum Superficialis MuscleThe flexor digitorum superficialis muscle flexes or bends the fingers, flexes the wrist and is a weak flexor of the elbow.Flexor Hallucis Longus MuscleFlexor Hallucis Longus bends the big toe when you curl up your foot. It is called 'Hallucis' as the word Hallux means great or big toe in latin.Flexor Pollicis Longus MuscleThe flexor pollicis longus muscle lfexes the thumb and wrist and is a weak flexor of the elbow.FormForm is expressed in terms of the quality of each repetition throughout the full range of motion. With good form, one should be able to reach the point of temporary muscular failure. Form involves moving the specified muscles involved in a particular exercise.Free WeightsBarbells, dumbbells, and related equipment. Serious bodybuilders use a combination of free weights and such nautilus exercise machines such as the smith machine to incorporate a balanced training regime. Free weights are generally preferred, because they allow the stabilizer muscles to be used.
