Answer two quick questions. This shows you what good, safe training looks like at your athlete's stage, and what to avoid. It is a guide for understanding, not a workout prescription.
Educational only. Not medical advice. This tool explains what is generally appropriate at each stage of development. It does not create a personalized program and does not replace a qualified coach, athletic trainer, or doctor who can see your athlete. If your athlete is in pain or in a growth spurt, check with a professional before training.
