Fitness trends change constantly.
Training principles don’t.
Despite new methods appearing every year, the same foundational ideas—progressive overload, consistency, recovery, effort—continue to produce results across decades.
This isn’t coincidence. It’s structural.
Trends optimize for attention. Principles optimize for adaptation. The human body responds to stress in predictable ways, regardless of branding or novelty.
New approaches often work temporarily because they renew focus. But over time, results stabilize around familiar principles because biology doesn’t update with trends.
This is why experienced lifters often simplify over time. As knowledge increases, unnecessary complexity falls away.
What remains are principles that align with how systems behave under load—not what looks impressive online.
The persistence of old-school training isn’t resistance to progress.
It’s evidence of convergence.
