Answer 2

An isometric exercise refers to any physical activity involving static muscle contractions. The term “isometric” is derived from the Greek roots “isos” (equal) and “metron” (measure), which means that during isometric exercise, muscle length is broadly unchanged and consequently joint angle remains the same.
