The Sam Portland Podcast

The Most Misunderstood Principle in Speed Training (Specificity vs General Work)


Listen Later

Welcome back to another solo podcast where we strip away the noise and get to the truth about adaptation, intensity, and real speed development.


In today’s episode, we unpack one of the BIGGEST reasons athletes fail to get faster:


👉 Trying to engineer specific outcomes with non-specific training.


Coaches everywhere fall into the trap of:


  • Over-analysing general strength work

  • Over-emphasising exercises that don’t transfer

  • Ignoring the Law of Accommodation

  • Forgetting the principle of specificity

  • And chasing “strength → power → speed” instead of “speed → power → strength”



This session will change how you program forever.


You’ll learn:


🔥 Why the upstream effect from strength → speed is massively overestimated

🔥 Why SPEED drives power and strength (not the other way around)

🔥 How to use the 21-day adaptation rule properly

🔥 Why soreness destroys continuity and speed development

🔥 How to apply specific strength for acceleration using band-loaded mechanics

🔥 The Learn → Load → Execute model for guaranteed progress

🔥 How to engineer positive adaptations without hamstring carnage


If you’re serious about developing speed in field sport athletes… this is essential viewing.
