maintaining, or pertaining to, the same length; of equal dimensions.

i·so·met·ric

(ī'sō-met'rik),
1. Of equal dimensions.
2. In physiology, denoting the condition when the ends of a contracting muscle are held fixed so that contraction produces increased tension at a constant overall length. Compare: auxotonic, isotonic (3), isovolumic.

adj. also i′somet′rical (-rĭ-kəl)
1. Of or exhibiting equality in dimensions or measurements.
2. Of or being a crystal system of three equal axes lying at right angles to each other.
3. Physiology Of or involving muscular contraction against resistance in which the length of the muscle remains the same.

Exercise
Muscle
Isometric Exercise against an unmoving resistance; isometric exercises consist of muscle contraction with a minimum of other body movements; isometric exercises build muscle strength and include weight-lifting or squeezing a tennis ball
Isotonic Dynamic exercise Isotonic exercise consists of continuous and sustained movement of the arms and legs; isotonic exercises are beneficial to the cardiorespiratory systems and include running and bicycling
Whole body
Low-impact aerobics Any type of aerobic exercise that promotes physical fitness, but does not stress musculoskeletal tissues, and joints; low-impact aerobic exercises include walking, swimming, bicycling
High-impact aerobics Any type of aerobic exercise that promotes physical fitness, at the risk of stress to musculoskeletal tissues, and joints; high-impact aerobic exercises include aerobic dancing, basketball, running, volleyball
