The physical side of development, done right. How to build strength, speed, power, and movement for baseball and softball players from first-ball through the pros. Bodyweight-first, matched to age and maturity, and grounded in the research, not the trends.
The full, plain-language guide to physical development at every age. What to build, what to avoid, and the three things that matter most. The thinking behind everything here.
Answer two quick questions and see what good, safe training looks like for your athlete's stage, and what to avoid. A guide for understanding, not a prescription.
A caution we take seriously: the popular "windows of trainability" idea from early LTAD writing is contested in the research. We treat stages as a planning framework, not a biological law. Anything on these pages without a source behind it gets cut.
Educational resource only. Not medical advice. These pages explain general principles of youth athletic development. They are not a personalized training prescription and do not replace a qualified strength coach, athletic trainer, or physician who can see your athlete. Around a growth spurt or with any pain, check with a professional first.
