The lexicon of muscle-building, and training - Part 19

After Arthur Jones sold Nautilus Sports/Medical Industries, Inc., in 1986, he founded MedX Corporation and designed the equipment there — primarily clinical evaluation and rehabilitation equipment. In 1991, MedX entered the non-medical exercise equipment field, with less costly machines based on the design of the medical units. Jones subsequently sold MedX Corporation. The Joneses were the brains behind three of the best brands of exercise machinery.

Erectors

Abbreviation for the erector spinae muscles, on either side of the spine.

Ergogenic aid

A product that improves physical or athletic performance, such as a performance-enhancing drug.

Ergometer

Apparatus on which exercise tests are done — for instance, a bicycle ergometer.

Estrogen

Any of several steroidal hormones produced chiefly by the ovary, responsible for the development and maintenance of female sex characteristics.

Exercise balls

Medicine balls are hard and come in different weights. Stability balls are soft and light, and come in different sizes — for instance, Swiss balls. Stability balls can be valuable for a limited number of exercises, such as the ball squat, and some abdominal exercises. Because of their instability, stability balls should never be used for pressing or bench pressing from, or for standing on while performing any exercise.

Exercise bar

Bar of about one-inch diameter, to fit exercise weight plates. Exercise bars come in varying lengths, as opposed to the Olympic bar that has a standard length and requires plates with a hole of about two inches diameter.

Exercise overlap

Different exercises that work at least some of the same muscles produce exercise overlap if used in the same program.

Exercises

The individual movements that work specific parts of the body. The words exercises and movements (and even lifts, in some cases), are used interchangeably. See Compound exercises, and Isolation exercises.

There are many exercises. Some of them are more valuable than others, but only a limited number can be used effectively in any given program. If an excessive number is used, results will be minimal or non-existent. Employing enough but not too many exercises, a balanced selection of them, and choosing ones appropriate to a given individual, or avoiding movements that are inappropriate to a given individual, is what good program design is about.

Exercise weight plates

Weight plates that have holes just large enough to fit onto an exercise bar, as opposed to Olympic plates that have larger holes in order to fit onto the thick ends of Olympic bars.
