What is a characteristic of isometric exercises?

Isometric exercises are defined by the muscle contractions that occur without any visible movement of the associated joints. This type of strength training involves tensing the muscles while keeping the body in a fixed position, allowing for sustained contractions without the muscles changing length or causing joint movement. Examples include activities such as planks or holding a wall sit, where the muscles are engaged but the position remains static.

The rapid movements and joint movements are characteristics of other types of exercises, such as dynamic or isotonic ones, which involve altering the position of the limbs and typically include a range of motion. Isometric exercises do not require special equipment, as they can often be performed using body weight alone, although equipment such as resistance bands or weights can also be utilized if desired.
