Alternating rhythmic stabilization: This technique is simply an extension of alternating isometrics in which the involved muscle groups co-contract.
Generally an active PNF stretch involves a shortening contraction of the opposing muscle to place the target muscle on stretch, this is followed by an isometric contraction of the target muscle.
But one can also perform
isometrics with almost any exercise.
Lying on your back with a doubled pillow under your knee and flattening it by straightening your leg and exerting force toward the floor is relatively

Isometrics are especially important before climbing down from a tree stand.
Q: In the October issue of your newsletter where you talk about the OsteoBall and
isometric exercises, you say it is good for people who have had heart attacks or who have hypertension.
It is possible to produce a computer-generated
isometric illustration of sufficient quality for most applications directly on a computer by manipulating the data from a scanned engineering drawing.
Producing
isometrics is done automatically by a batch process that lets the user specify the line numbers that are to be extracted.
While many studies have examined the effect of diet and dynamic exercise on muscle strength and weight loss, none have examined a combined
isometric exercise and diet program.
Isometric exercise can be used for strength training.
