The age group typically advised to start strength training is generally between 8 to 12 years old, once children have developed the ability to understand and follow instructions. This age is considered appropriate to begin learning proper techniques with light weights or bodyweight exercises, focusing primarily on form and consistency rather than heavy lifting. Starting early can help foster a lifelong appreciation for fitness and health, building a strong foundation for more advanced training later in life, while reducing the risk of injury as they grow.
