Lesson #3 from 2 Decades of Triphasic Training: Why the Aerobic System Is Your Underrated Weapon


What up - it is I (Dr Mike T Nelson here) writing to you from S. Padre Island TX to discuss today why when most strength coaches "out there" (not here as you know what is up) hear “aerobic training,” they either tune out or picture long, boring runs.

...As you know, the aerobic system is the secret to more max-effort lifts, faster recovery, better repeat sprint ability, and longer-lasting performance gains!

That’s not a pipe dream. It’s what happens when you start treating aerobic capacity as a performance multiplier—not a conditioning afterthought.

Conditioning = Control, Not Just Tiredness

You’ve probably heard this quote before:

“Any idiot can make another idiot tired.” – Verkhoshansky

The goal isn’t to wear athletes down—it’s to build systems that help them bounce back faster, recover deeper, and sustain high output over time.

Think of conditioning not as punishment, but as readiness insurance.

Why the Aerobic System Matters for Strength

A robust aerobic engine improves:

  • heart rate variability and vagal tone
  • CO₂ tolerance and oxygen efficiency
  • tissue recovery between reps, sets, and sessions

If your athlete can recover faster between heavy squats or hard sprints, they can do more quality work. That adds up.

And here’s the kicker: the aerobic system is what gets you back to baseline. It’s the system that resets the dimmer switch between explosive outputs.

Tools to Build Aerobic Capacity Without Killing Gains

Triphasic II covers a variety of methods that develop aerobic conditioning without dragging down strength or power.

Here are a few we use regularly:

  • Contralateral Circuits (PHA): upper/lower cross-body movement pairs done for time to target the aerobic system without taxing strength
  • Coordinated Conditioning: pairing high-intensity lifting days with rower sprints or sled work, matching time domains
  • Nasal Breathing + HRV Training: to improve CO₂ tolerance, vasodilation, and autonomic control
  • Dimmer Switch Model: training athletes to modulate energy output instead of blasting redline every set

None of this is fluff—it’s how you help athletes handle more work, with less wear and tear, and longer staying power.

Weekly Structure Example

Here’s a simple split that supports both strength and aerobic development

  • Monday: Lift
  • Tuesday: Continuous aerobic work
  • Wednesday: Lift
  • Thursday: Aerobic work again
  • Friday: Lift
  • Saturday: Lactate-based work
  • Sunday: Off (long walks, low stress)

You’re not just building a motor—you’re giving them a recovery system they can actually rely on.

PS - Here is what Hayan had to say:

"My favorite part of the book is the guidelines that it lays out for how to train properly, especially for the aerobic phase which is extremely important for adapting to stimulus faster than your competition." - Coach Hayan

Dr Mike T here and I am stoked to let you know that the wizard himself Coach Cal Dietz has a breakthrough new program that's going to change how you think about ACL injuries. As you know, non-contact ACL injuries are absolutely skyrocketing... ...but here's the thing: you don't have to accept this as "just part of the game." Cal has cracked the code on something that's been hiding in plain sight for years, and he's put together a brand new program that shows you exactly how to slash ACL...

Two things for you today from raining Minnesota 1) New printer for the Triphasic Training II book We have a new printer for the Triphasic Training II book now. Same book, same layout, and no difference at all, but this will serve as a back up and we can control all aspects of the process now instead of bowing down to Amazon if anything were to happen. You should not notice anything different, but if you live outside of North America, it may be cheaper on Amazon as the new printer ships from...

I know I am going to sound like a broken record here, but this system seems to still get no love. As you know I am talking about…. ….The aerobic system. In Triphasic Training II, we dedicated almost 25% of the book to aerobic capacity—and for good reason. This isn’t just about long runs or “getting in shape.” It’s about building the engine that drives recovery, repeatability, and even max-effort lifting. “A bigger aerobic system equates to a better-functioning athlete who can absorb more...
