Background: Cigarette smoking is the major cause of premature death. It accounts for 28% of all cardio vascular diseases and 40% of respiratory diseases as it is associated with impaired pulmonary function. Exercise is an effective and low cost of treatment which can promote good health of a smoker. Research indicates that individuals who maintain an exercise program are more likely to give up smoking than those who quit exercising. Methodology: 150 subjects were included in the study and divided into two groups Group A (resistance exercises) and Group B (Walking). The exercises protocol was given for six weeks. Pre post PEFR and VO2 max was calculated. Results: both the groups showed improvement post intervention (p<0.05) whereas resistance group showed better improvement than the walking group (p<0.05). Conclusion: Aerobic and Resistance exercises both showed significant improvement in PEFR and VO2 max in smokers, however the resistance exercises showed better improvement in the cardiovascular and pulmonary function.
