Dirty bulking is a method of rapid weight gain that’s usually paired with high-intensity resistance training and used by various athletes to promote muscle and strength gains. It involves consuming more calories than you burn, which can lead to weight gain in the form of muscle or fat. However, dirty bulking takes this a step further and can be defined as a period of unrelenting weight gain by any means necessary to promote muscle and strength gains.

Dirty bulking is different from clean bulking, which involves consuming a surplus of calories only from nutritional sources such as fruits, vegetables, and clean proteins like lean meat or nuts. Clean bulking is considered the safer way to gain mass and strength without excessive amounts of body fat.

While dirty bulking can be quite effective for gaining weight, its unrestrictive nature can lead to negative health effects. People who follow a dirty bulking practice will aggressively go way over their normal calorie intake, without considering the quality or nutritional density of the food they are consuming. This can lead to significant gains in both scale weight and body fat, which may not be healthy in the long run.

In summary, dirty bulking is a method of rapid weight gain that involves consuming more calories than you burn, which can lead to weight gain in the form of muscle or fat. It is usually paired with high-intensity resistance training to promote muscle and strength gains. However, its unrestrictive nature can lead to negative health effects, and clean bulking is considered the safer way to gain mass and strength without excessive amounts of body fat.
