Best Answer

An isometric contraction is when your muscles contract but there is no movement.

To do one you just need to apply a force to an immovable object. In the strength training sense it is done typically using a power rack or weight lifting cage. The isometric contraction is done typically at the most difficult point of a isotonic lift and is held for 8-12 seconds at maximum exertion. The support pins of the power rack are set at the desired height and a steel bar is then pushed against them to perform the isometric contraction.
