Methodology

What's actually controllable
Three things make a real difference and stay fully within someone's own hands: how nutrition is structured, how stress is managed, and how seriously recovery is treated. These three consistently move the needle on hormonal efficiency.
Where coaching reaches its limit
Beyond those three, genuine hormonal issues need to be addressed at a supplement level or through medical care, not through training adjustments alone. Being honest about that line is part of doing this work properly.
