to work your legs
An exercise mat is optional for crunches and other types of exercise. Crunches should be done wearing comfortable clothes, and on a surface that is firm but comfortable- such as a carpeted floor or a hard floor with a mat.
Crunches do not stunt a persons growth. Crunches can be part of an exercise routine. Crunches help strengthen the stomach muscles.
