Limited exercise ability, muscle damage.

When our muscles grow, they need enough oxygen to support them. When you smoke a lot, they will lack enough oxygen to grow. It is very unscientific to start smoking right after fitness. Because this will not only reduce muscle endurance, but also limit exercise ability to some extent.

A sports magazine published relevant research and found that long-term smoking will reduce the lack of oxygen supply for muscle growth and directly reduce the number of blood vessels.

Physical endurance is weakened, affecting cardiopulmonary function.

I believe that people who have long-term smoking habits have such experiences. After smoking, the cardiopulmonary function is better than before, the vital capacity decreases not a little, and the physical endurance will also decrease.

If a person's frontal muscle endurance and vital capacity get worse, the training effect will not be much better. If you just do some simple low-intensity exercise, it is not particularly obvious. If you do high-intensity exercise, you will have a deep understanding of endurance. For example, when you do hard training and squat, you will feel very hard.
