ECA, ECA Stack
Ephedrine, Caffeine, and Aspirin, a popular and effective thermogenic combination of drugs used for weight loss and energy. Ephedrine is a stimulant that acts to increase alertness, energy, and body temperature, thus increasing caloric expenditure. Caffeine inhibits the body's natural tendency to counteract the stimulant effects of ephedrine, so that the two of them used together increase caloric expenditures more than the sum of the increases caused by each one used individually. The most common dosage is 200mg of caffeine taken with 20mg of ephedrine ( = 25mg of ephedrine hydrochloride) three times per day, the third dose being taken not later than dinnertime. Caffeine and ephedrine act as appetite suppressants, which has weight-loss benefits as well.
60mg of aspirin (about a quarter of a standard aspirin tablet) is often added to the stack, but studies have not shown conclusively that ECA is more effective for weight loss than ephedrine and caffeine without aspirin.
Please note that ephedrine and caffeine also have a diuretic effect, so some weight loss will be due to a loss of water and not fat.

The muscle contracts as it lengthens. Example: During a bicep curl the bicep contracts eccentrically as the weight is lowered.

Thin and linear body type .

see essential fatty acids

Minerals such as sodium, potassium, magnesium, and calcium used by cells in the creation and elimination of membrane potentials used to propagate nerve impulses and muscular contraction

Glands that produce chemicals released into the bloodstream. The pituitary and adrenal glands are endocrine glands; salivary glands and sweat glands are not.

Rounded body type with small shoulders.

A protein catalyst; enzymes are essential for digestion and both the synthesis and breakdown of proteins, hormones, and other substances in the body.

An herb, also known as Ma Huang and "Mormon Tea" containing ephedrine and pseudoephedrine

A common beta agonist used to relieve the symptoms of asthma; it dilates bronchial passages and is also a stimulant

Also known as adrenaline, epinephrine is a sympathomimetic hormone produced by the adrenal glands that accelerates heart rate, constricts blood vessels, raises blood pressure, dilates breathing passages, and accelerates the peristaltic motion of the muscles lining the intestines.

Epiphyseal Plates
The "plate" on the end of a bone, particularly the long bones of the arm and leg which remain unfused to the rest of the bone during growth. Once they become fused, these bones cease to grow longer.

Tending to increase muscular power, endurance, or size

Essential Amino Acids
Amino acids which cannot be synthesized by the body from other amino acids and, thus, must be present in the diet: leucine, isoleucine, lysine, methionine, phenylalanine, tryptophan, and valine

Essential Fatty Acids
Unsaturated fatty acids which cannot be synthesized by the body and are used as the starting point for the biosynthesis of necessary metabolic and hormonal chemicals.

Estrogen, Estrogenic
There is no one hormone named "estrogen"; estrogens are hormones that induce or accentuate female sexual characteristics (as well as performing other functions, depending on the specific hormone). Estrogens include estrone, progesterone, and estradiol. "estrogenic" means "tending to induce the same effects that estrogen does"; while chemicals that mimic testosterone are almost nonexistent in nature, our food supply, and our environment, estrogenic chemicals are common. Some of these, such as genestein (found in soy) have gotten considerable press coverage because they are weak estrogens, meaning that while they can occupy an estrogen receptor , they do not stimulate the receptor to as great an extent as the body's own estrogens would, which can reduce one's risk of estrogen-related cancers and tumors, most notably breast cancer. However, for this last effect to occur, the weak estrogens must be present in the body in sufficient quantity so that they displace existing natural estrogens that would otherwise stimulate available estrogen receptors--and the total degree of stimulation produced by the greater number of occupied receptors must be less than would have been produced by the naturally present estrogens alone.
Other estrogenic chemicals are found in plastics and pesticides and exert harmful developmental effects by disrupting the normal hormonal events that take place in humans and animals.

the act of straightening a joint or returning a joint to it's anatomical position.

outside the cell or cells (in the bloodstream, lymph, etc.) as opposed to inside

EZ-Curl Bar
a short barbell with a shaft bent like a stretched-out 'w' typically used for performing curls with the hands turned inward more than they would be using a straight bar, putting less strain on the wrists. A typical olympic EZ-curl bar weighs around twenty pounds, though there's no "official" standard weight. Standard (takes plates with 1" holes) versions would be lighter, typically ten to fifteen pounds.
