Answer to Question 2
B
Exercises that improve muscle strength are important for balance, strong bones, and metabolic processes. Relative intensity is the level of effort required by a person to an activity. When using relative intensity, people pay attention to how physical activity affects heart rate and breathing. Muscle strength is not a therapeutic concern. Muscle retraining refers to muscles that have been trained, detrained, and trained again and is not a therapeutic concern. Muscle definition is a qual-ity valued by bodybuilders, but it is not a therapeutic concern.
