The lexicon of muscle-building, and training - Part 16


Easy gainer

Opposite of hard gainer. Easy gainers are blessed with terrific heredity or genetics for muscle-building, and have highly responsive bodies. Genetic phenomena further enhanced by drug support are the ultimate easy gainers.

Some potential easy gainers are obvious by their appearance before starting muscle-building, because they are already muscular, strong, and lean; but, for others, their “easygainingness” isn't apparent until they start lifting weights, whereupon they grow quickly almost regardless of how they train. It's the ability of easy gainers to respond to training methods that typical trainees get nowhere on that makes easy gainers poor role models.

As easy gainers close in on their drug-free potential for bodybuilding, they may find gains hard to make, but until that point they found gains easy.

Eccentric action

The lengthening of a muscle. For instance, when you lower your hand through extending your elbow, your biceps muscle is lengthened because of the eccentric action. Eccentric actions are often abbreviated to eccentrics. Eccentrics are also often called negatives.


See Bodytype.


Swelling, an accumulation of fluid in the body.


Essential fatty acids, required for a healthy diet.

Electrocardiogram (ECG or EKG)

Recording of the electrical activity of the heart, used to investigate heart function.


Any of certain inorganic compounds — mainly sodium, potassium, magnesium, calcium, chloride, and bicarbonate — that dissociate in biological fluids into ions capable of conducting electrical currents, and constituting a major force in controlling fluid balance within the body.

Elliptical machine

Also called an elliptical, elliptical cross trainer, elliptical exerciser, elliptical fitness machine, and elliptical glider. It's a machine that simulates a blend of walking, cycling, and skiing, through a single action.

Endocrine system

The glands and tissues responsible for production and secretion of hormones.


See Bodytype.


Substance used by the nervous system, composed of amino acids. Endorphins are made by the pituitary gland and aid the body's management of pain and emotions. Two endorphin-like compounds produce enkephalins that are thought to be responsible for the high that some runners experience.


Ability of a muscle to work continually over a sustained period.


A catalyst of metabolic reactions, that is, a substance that speeds up reactions.
