Does lifting weights stunt growth?

Lifting weights does not inherently stunt growth. This misconception has been addressed by Dr. Kyle Gillett, who clarified that lifting heavy weights by itself does not stunt growth. However, the practice known as "dirty bulking"—deliberately overeating to gain muscle and fat—can indeed affect growth. Dirty bulking can lead to early puberty due to increased body fat, which can alter hormone levels and potentially limit height due to earlier closure of growth plates in bones 1.

It's particularly important for young individuals in their formative years to focus on healthy eating and exercise patterns rather than trying to increase their body weight excessively through poor nutritional choices. Regular and moderate weight training without excessive caloric intake is generally considered safe and beneficial 2.
