An isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term "isometric" combines the Greek words "Isos" (equal) and "metria" (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction strength may be varied. This is in contrast to isotonic contractions, in which the contraction strength does not change, though the muscle length and joint angle do.
Isometric exercises are thousands of years old with examples listed from the static holds in certain branches of yoga or oriental martial arts. Isometric exercises 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 regimens.
The IGrip is a portable exercise device that incorporates the Power of Isometrics to help build power, strength, and lean muscle. Work out anywhere-anytime and hold a contraction for 7 seconds or more to Get Ripped Fast. The secret lies in the ability of the IGrip to electronically measure both the applied Push and Pull force. Timed static (stationary) contractions with the IGrip eliminates the need to do dozens of repetitions with weights. All that's needed is 7 or more seconds with the IGrip to feel the power.
