Introduction to Cardio: Why It Matters More Than You Think

Want to halve your risk of heart disease, type 2 diabetes, dementia, depression, anxiety, and even premature death? You don’t need a magic pill—just better cardio.

In this post, we’ll break down some of the most powerful methods and science-backed techniques to upgrade your cardiovascular fitness, drawn directly from a workshop we delivered to our Storm Fitness Academy students. Whether you’re a personal trainer or just someone serious about your fitness, get ready to level up your endurance training.

Why Cardio Training is Essential

Cardiovascular training isn’t just about running further or faster—it’s about living longer and better. When done well, it:

  • Improves your health span (not just your lifespan)

  • Releases mood-boosting hormones like endorphins, dopamine, serotonin, and oxytocin

  • Lowers your resting heart rate by strengthening your heart—especially the left ventricle

  • Boosts oxygen uptake and delivery across the body

  • Enhances insulin sensitivity, reducing risk of type 2 diabetes and fat storage

  • Supports bone and joint health, especially with weight-bearing activity

How Much Cardio Do You Need?

According to UK government guidelines:

  • 150 minutes of moderate-intensity activity per week (where you can talk but not sing), or

  • 75 minutes of vigorous-intensity activity per week (where speaking is difficult)

Each minute of vigorous cardio counts as two minutes of moderate, so you can mix and match. The sweet spot? Aim for 150–300 minutes of moderate or 75–150 minutes of vigorous activity weekly.

The Science of Endurance Performance

To really understand and improve cardio performance, we break it down into three core areas:

  1. VO₂ Max – The maximum amount of oxygen your body can use. The higher it is, the better your engine.

  2. Lactate Threshold – The point where lactic acid builds up faster than your body can clear it. Train this to go harder for longer.

  3. Movement Economy – How efficiently you move, combining technique, posture, and strength-to-weight ratio.

Train all three, and you’ll not only go further—you’ll go faster and feel better doing it.

Advanced Training Techniques to Supercharge Your Cardio

Here’s where the fun starts—these are the training methods that help clients (and coaches) smash plateaus.

1. Threshold Training

Train at 80–90% of your max heart rate—your “comfortably hard” zone. It feels tough, but sustainable. This helps your body clear lactic acid more effectively, allowing you to perform at higher intensities for longer.

Tip: Estimate max HR as 220 minus your age. Multiply by 0.8 and 0.9 to find your threshold training zone.

2. Interval Training

High-intensity intervals are brutal—but they work. One of the most effective protocols?

The Norwegian 4×4 Drill:

  • 4 minutes at 95% max HR

  • 3 minutes at 60–70%

  • Repeat 4 times
    This method has been shown to increase VO₂ max by up to 10% in just weeks.

3. Fartlek Training (Speed Play)

A more intuitive way to train multiple heart rate zones in one session. Alternate between easy, moderate, and hard efforts—ideal for building mental and physical tolerance to intensity.

4. HIIT (High-Intensity Interval Training)

Short bursts of high effort followed by rest or low-intensity work. For example:

  • 60 seconds hard

  • 30 seconds light

  • Repeat 8–10 rounds

Great for time-poor clients who still want big gains in fitness and fat loss.

5. Tabata Training

Named after Dr Tabata, this method involves:

  • 20 seconds flat out

  • 10 seconds rest

  • Repeat for 4 minutes (8 rounds)

Research has shown Tabata can match (and sometimes outperform) 40 minutes of steady-state cardio—making it one of the most time-efficient protocols around.

6. Cardio Circuits

Combine cardio machines or equipment in a circuit-style format:

  • 4 minutes on treadmill

  • Short rest

  • 4 minutes on rower

  • Repeat with bike, ski erg, etc.

This helps maintain effort without getting stuck in one movement pattern and adds variety to training.

Heart Rate Zones – A Quick Breakdown

Zone % Max HR Training Benefit
1 50–60% Active recovery, warm-ups
2 60–70% Aerobic base building, fat burning
3 70–80% General cardio fitness, stamina
4 80–90% Lactate threshold, race pace
5 90–100% Maximal effort, VO₂ max improvement

Know your zone. Train with purpose.

Wrapping Up

If you want real progress, cardio can’t just be a tick-box. You need to:

  • Understand the science

  • Train across different heart rate zones

  • Select methods that match your (or your client’s) goals

Whether you’re chasing a sub-20-minute 5K, improving your football fitness, or just want to future-proof your health, cardio training is the key.
