Below is a list of commonly used terms and their meanings. Before you ask what something means, try to check here first.

17 AA = 17 Alpha Alkylated
AAS = Anabolic Androgenic Steroid
Abduction = moving a limb away from the midline of the body. An example is moving an arm from the side of the body to shoulder height.
Adduction= moving a limb toward the midline of the body. An example is bringing the arm to the side from an extended position at the shoulder.
Acclimitization = gradual adaptation to a changed environment, such as higher or lower tempuratures, higher altitudes, etc..
Accomodation = refers to the process by which the response to constant stimuli decreases with repeated application. Novel and beneficial stressors yield “supercompensation” whereas monotonous/detrimental stressors yield stagnation or decay.
ADP = adenosine diphosphate
Aerobic Exercise = With Oxygen. Prolonged moderate intensity exercise that uses up oxygen at a rate at or below the the level that cardiorespiratory system can replenish it. Examples are running, walking, cycling, and swimming. Develops cardorespirotory fitness and is used to burn fat to achieve maximum defintion, but can be highly catabolic if done in excess.
Agonist = muscle that is contracting during a movement and which is primarily responsible for the movement of a certain bodypart.
Alternated grip = one hand suppinated and the other pronated.
AMP = adenosine monophosphate
Anabolism = from the Greek: anabole, "to build up". The phase of metabolism in which simple substances are synthesized into the complex materials of living tissue, or more simply, where larger molecules are built up from smaller ones. The process involving a sequence of chemical reactions that constructs or synthesizes molecules from smaller units, usually requiring input of energy (ATP) in the process, that energy being derived from catabolic processes. The building up of proteins from amino acids is an example.
Anerobic Exercise = higher intensity exercise than aerobic exercise which uses up oxygen more quickly than it can be replenished in the muscles. Bodybuilding is anerobic exercise and it burns up muscle glycogen to supply energy to the working muscles.
Antagonist = a muscle that counteracts, slows down, or stops the movement of the agonist. It lengthens when the agonist contracts. It assists in joint stabilization and braking the limb at the end of a fast movement.
Anterior = Front
AR = Androgen Receptor
AS= Anabolic Steroids
ATF = Ass to Floor
ATG = Ass to Grass
ATP = Adenosine Triphosphate – provides the energy for muscle contraction and thus all human movement.
AxB= reps times sets
BB = Body Builder or Body Building
BB= barbell
BCAA = branched chain amino acids. Valine, isoleucine, and leucine.
Biaxial Joints = Such as the ankle and wrist. They allow movement about two perpendicular axis.
BiD = twice a day
Bilateral = Two sides or both sides.
Biomechanics = the physics of human motion. A study of the forces produced by and acting on the body. There are three terms associated with biomechanics: kinematics, kinetics, and kinesiology.
BF% = Body Fat %
BMR= Basal metabolic rate. Refers to the amount of heat produced by the body druing resting conditions. Reflects the minimum level of energy required to sustain the body's vital functions in the waking state.
BW= Body Weight
Cardinal Planes = three imaginary planes which bisect the body in three dimensions.
Cartilaginous Joints = joints which allow only limited movement, such as the intervertebral discs
Catabolism = from the Greek, katabole, meaning “‘throwing down’”. The metabolic breakdown of complex molecules into simpler ones, often resulting in a release of energy. The process involving a series of degradative chemical reactions that break down complex molecules into smaller units, usually releasing energy in the process.
CEE= Creatine Ethyl Ester
Cervical Spine = Also known as the neck, is comprised of seven vertebral bodies (C1-C7) that make up the upper most part of the spine. These vertebrae connect the spine to the skull.
Circuit Training = going form on exercise to another (10 to 20) as quickly as possible in a circuit around the gym, keeping the pulse rate high. A rest period of two to five minutes is taken and then the circuit is repeated for a planned number of times.
Circumduction= movement in 360 degree range (circle arm around)
CLEN = Clenbuterol
CM= Citrulline Malate
CNS= Central Nervous System
Compound Exercise = Also called a basic exercise. Multi-joint movement that involves a large number of muscles (and generally the largest muscle groups like thighs, back or chest) and enable you to lift the heaviest weights. Examples are squats, bench presses, deadlifts, and pull-ups.
Concentric Movement = the part of a movement where the muscle shortens or contracts. It is the lifting part of the exercise such as when you press a barbell from your chest. Also called the positive.
CYP= Testosterone Cypionate
DART = Syringe/Needle
DB = Dumbell
DBOL= Dianabol (Methandrostenolone)
DECA= Nandrolone Decanoate
Detraining = the loss of training adaptations due to prolonged abstinense from training. The time course of detraining is different for different adaptations with aerobic endurance training being quickest to detrain and strength training being much slower.
DHT= Dihydrotestosterone
Dislocation = the complete displacement of a joint surface often resulted in severe laxity or instability
Distal= The more (or most) distant of two (or more) things. For example, the distal end of the femur (the thigh bone) is the end down by the knee; the end more distant from the torso. The end more distant from the torso or trunk. The opposite of distal is proximal.
DMSO= Dimethyl Sulfoxide - Topical enhancer
DOMS = delayed-onset muscle soreness
DNP = Dinitrophenol
ECA= Ephedrine/Caffeine/Aspirin
Eccentric Movement = the part of a movement where the muscle elongates. When you lower the weight back to the starting position. Also called the negative.
ED = Every Day
EFA = essential fatty acid
EPOC = Excess Post Exercise Oxygen Consumption
Epimysium = fibrous connective tissue that covers the body’s more than 430 skeletal muscles (deep fascia)
EOD = Every other day
EQ= Equipoise (Boldenone Undecylenate)
Extension = increase joint angle (tricep extension, leg extension)
Fatty Acid = an organic compound composed of a carbon chain with hydrogens attached and an acid group at each end
Flexion = decrease joint angle (bicep curl)
Fibrous Joints = joints which allow virtually no movement, such as the sutures of the skull
FINA = Finaplix (Trenbolone Acetate)
Frontal Plane = (coronal or lateral cardinal plane) line which splits the body vertically into front and back halves of equal weight. See sagittal and transverse.
g= grams
GH = Growth Hormone
GI= Glycemic Index
Golycerol= an organic alcohol composed of a three-carbon chain which can serve as the backbone for a triglyceride. When free, glycerol has a hydroxyl group attached to each carbon and when part of a triglyceride, each carbon is attached throught an oxygen bridge to a fatty acid.
Glycolysis = the breakdown of carbohydrates (gycogen or free glucose) to produce ATP
GVT=German volume training
GYNO = Gynomastica (Bitch tits)
HIIT= High intensity interval training
HIT= High intensity training
Hook grip = grip where the index and middle fingers are wrapped around the thumb, which is palced against the bar first, with the ring and little fingers holding the bar rather loosely which can add up to 10% to any pulling motion used.
HPTA = Hypothalamic Pituitary Testicular Axis
HST= Hypertrophy Specific Training
