I guess what the landlord means is that smoking during muscle training will not affect the effect, because everyone knows that smoking is harmful to health. Needless to say, smoking during the fitness cycle has no direct impact, just not smoking during fitness, or just after fitness. At this time, the lung exercise is large and the blood circulation is faster. Smoking will cause several times more damage to various organs of the body than usual, and it will also subtly affect your fitness effect.
