Do I need to become a runner to get my conditioning training in?

Conditioning is basically your body’s ability to do work and keep doing it without falling apart. It’s about how efficiently your body produces energy, uses it, and recovers between efforts.

That’s why two people can do the same workout and have completely different experiences. One is gasping halfway through, the other is uncomfortable but still working. Same exercise, different conditioning level.

What’s actually happening in your body

When you train conditioning, you’re stressing a few key systems at the same time:

• Your heart and lungs (cardiovascular system)

• Your muscles’ ability to use oxygen

• Your ability to tolerate fatigue and byproducts of effort (hello lactic acid)

• Your recovery speed between bursts of work

Over time, your body adapts by becoming more efficient. Your heart doesn’t need to beat as fast for the same output. Your muscles get better at using oxygen. And the same workload feels less chaotic. It’s not that the workout gets easier. It’s that you get more efficient at handling it.

It’s not just “cardio”

Conditioning gets confused with certain types of cardio, like running, cycling, swimming etc, but that’s only a piece of it. You can build conditioning through a lot of different methods:

• Running intervals or steady runs

• Surfing, playing outside with your dog or kids

• Circuit training

• Mixed strength + conditioning sessions

• Sport-specific work

  
  

What matters isn’t the format. It’s the density of effort and how your body responds to repeated stress with incomplete rest.

The energy systems (in simple terms)

Your body has different ways of producing energy depending on intensity and duration.

• High intensity, short bursts rely on quick energy systems (ex. anaerobic systems, carbs)

• Longer efforts rely more on oxygen-based systems (ex. aerobic systems, fats)

• Most training sits somewhere in between

Conditioning is really just training how smoothly you can move between those systems without crashing. That’s why someone can be strong in the gym but still get tired very quickly when rest is taken away. Different system, different adaptation.

Why conditioning matters

You don’t need to be an endurance athlete for conditioning to matter. It shows up in much more normal ways than people think. Like:

• Not feeling destroyed after a fast-paced workout

• Recovering between sets without needing long breaks

• Walking up a huge flight of stairs without feeling like you need to faint

• Paddling out at Ribeira D’Ilhas on a 2-meter swell

  
  

It’s less about extreme fitness and more about not hitting a wall every time effort stacks up, which we all face at some point.

The mistake most people make

A lot of people think conditioning means going all out until they collapse. That approach works short term, but it’s not the point. Real conditioning is about repeatable effort. Being able to work, recover a bit, and work again without your output falling apart immediately. You don’t need to destroy yourself. You need consistency and enough challenge for adaptation to happen.

The real takeaway

Conditioning is what sits behind your ability to train harder, recover faster, and handle more volume without feeling like every session is a survival exercise. It’s not flashy. It’s not complicated. But it quietly changes how much work your body can actually handle.
