Hello, your question is very good. The biggest taboo for fitness enthusiasts is smoking after exercise. When you exercise, the alveoli in your lungs will open completely. At this time, smoking a cigarette is equivalent to smoking a box of cigarettes. The amount of nicotine and cigarette tar is dozens of times that of normal smoking! I am a fitness enthusiast, and I haven't smoked since I finished exercising. Smoking itself is harmful to fitness and even more harmful to my health.
