The Swing: A Better Way to Think About VO₂max

The Swing

Improving VO₂max isn’t simply about training harder or pushing your heart rate higher. It’s about timing.

A good analogy is to think of yourself on a swing. Each time you push at the right moment, you add energy to the movement and the swing rises higher. But if you push too hard or at the wrong moment, you can disrupt the rhythm and actually reduce your momentum.

Training works much the same way.

Stimulus → fatigue → recovery → adaptation → higher capacity → next stimulus

A hard workout provides the stimulus. Recovery allows the body to absorb it. The next well-timed workout builds on what came before.

This is why more training isn’t always better. A workout that creates a strong stimulus with manageable fatigue can be more valuable than one that simply creates more stress.

The 4×4 Example

A 4×4 interval session illustrates the idea well.

Each interval is a deliberate push:

Push → recover → push → recover → push → recover → push

The goal isn’t to destroy yourself in the first interval. It’s to produce four effective efforts that work together.

The question isn’t:

“How hard can I push?”

It’s:

“How can I push in a way that makes the next swing higher?”

Closing Thoughts

VO₂max development is a balance between stimulus, recovery, timing, and consistency.

You don’t make a swing go higher by pushing randomly or constantly pushing harder. You work with its rhythm.

Training is no different.

The goal isn’t to train harder every day. It’s to know when the next push will make the swing go higher.
