How do 12 year olds get abs?

Children should not be focusing on developing muscular appearances such as abs. Children should focus on developing healthy habits and a well rounded understanding of nutrition and exercise rather than attempting to achieve a certain body type.

It is important for children and adolescents to establish healthy habits and engage in regular physical activity for overall health and well-being, but any effort to develop specific muscle groups should be done under the guidance of a healthcare professional.

A child's body is still developing and attempting specific training for appearance related reasons may lead to potential health issues.
