Constant Load Boosts Predictability, Fuels Champion Performance
Exactly. Everyone talks about tapering the load for performance. Few talk about tapering the load for stability. At a constant load, Fatigue plateaus much quicker than fitness (half-life of ~7 days) This means, if you hold the load constant, you don't just get faster...

Geroscience Should Prioritize Healthspan, Not Just Lifespan
