To determine the Effects of 6 weeks of Step Aerobics Training on Pulmonary Functions among females with sedentary life style. Traditional aerobic training programs has great effects to improved pulmonary functions in individuals with sedentary life style but on the other hand there is another type of aerobic training named step aerobic which is different from traditional training up-to knowledge has less work on pulmonary function but effective on functional score, and walking velocity this gap further need to identify. This study will help us to choose either of training program to get maximum beneficial outcomes particularly on pulmonary function test on female students with sedentary life style.

A sedentary lifestyle is defined as an individual living with very little or no physical activity. In daily routine the person spending most of his or her time in watching television, playing games on mobile ,using internet, reading books , often sitting or lying down while doing these activities.

Exclusion Criteria:

• Asthmatic patients
• Any history of Malignancies.
