Smoking will affect muscle growth and affect the endurance and strength of our bodies. We all know that the main body of muscle is composed of protein and carbohydrates, and its density is three times that of fat. The process of muscle gain requires a lot of nutrition intake, while the process of muscle exercise requires a lot of energy and oxygen.

However, after you smoke or smoke secondhand smoke, because hemoglobin in our blood is more easily combined with carbon monoxide, our muscles can't get enough oxygen supply in the blood at first, and the metabolism of muscle cells will be hindered. Secondly, the chemical components in smoke will stimulate blood vessels to contract, leading to the loss of nutrients in our muscles. Once we lose our nutritional supplement, even if you practice hard, it won't help.

Fitness precautions

People who gain muscle should pay attention to dietary supplements and add meals half an hour after fitness. For example, supplementing protein and carbohydrates can promote muscle repair and avoid fat accumulation. Those who reduce fat should control their diet, eat less at dinner and don't eat for 4 hours before going to bed, which can improve the efficiency of burning fat.

Learn to keep fit, not just for three minutes. Don't insist on fitness for more than 3 months, and don't say that fitness has no effect. Stick to it less than 3 times a week, and don't say that you are working out. Fitness is a fair thing. The longer you persist, the more benefits you will reap.
