Can a 9 year old have a sixpack?

Yes, a 9-year-old can develop visible abdominal muscles or a "six-pack," but this is often due to low body fat percentage rather than targeted muscle training. Children's bodies are still developing, and factors like genetics, diet, and overall physical activity play significant roles. It's important for children to focus on overall health and fitness rather than aesthetics. Encouraging a balanced diet and regular exercise is key for their growth and development.
