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
