If you belong to a gym, you might be surprised to see staff members and trainers puffing cigarettes. While this is not a common occurrence, many individuals in the diet and exercise industries develop habits that negatively impact their health. Smoking is a bad thing no matter how you cut it. It not only increases your risk of heart disease, respiratory disease and cancer, it also causes poor physical performance and minimizes endurance.
