Jym is the name of a small hand held, battery-operated personal therapeutic exercise device. Jym uses the principals of isometric exercise. Isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. This is reflected in the name; the term "isometric" combines the prefix "iso" (same) with "metric" (distance), meaning that in these exercises the length of the muscle does not change, as compared to isotonic contractions ("tonos" means "tension" in Greek) in which the contraction strength does not change but the joint angle does.

History
Isometric exercises are thousands of years old, with examples from the static holds in certain branches of yoga or Chinese martial arts.

Isometrics were first brought to the modern public's attention in the early days of physical culture, the precursor to bodybuilding. Many of the great bodybuilders of the day incorporated isometric exercises into their training regimes. Contrary to popular opinion, The Charles Atlas "Dynamic Tension" Course did not include any true isometric exercises, but rather Self-Resistance (that is: Pitting one limb against the other) and Bodyweight Calisthenics. which he learned from the "Conscious Evolution" course of Alois P. Swoboda. Isometrics fell out of favor as it was discovered that many of the principal advocates were using anabolic steroids to enhance their gains.

Jym has been invented as a new way to incorporate the advantages of isometric exercise and to make it a fun way to exercise where sometimes people can only do isometrics. Often females have not bneem able to use the large bulky isometric machines now both females and males can
