Zone 2 training has taken over the endurance world — but is it actually the key to better performance, or just another fitness trend?

In this episode of The Performance Podcast, we break down the science behind Zone 2 training, aerobic base development, mitochondrial health, and polarized training models. You’ll learn what Zone 2 actually does physiologically, why it improves fat oxidation and metabolic efficiency, and where it fits into a smart endurance training plan.

We dive into research from Dr. Iñigo San Millán, Dr. Stephen Seiler, and foundational studies on mitochondrial adaptation and VO₂ max development, plus real-life examples for runners training for a 5K, half marathon, or marathon.

If you’re wondering:
• Does Zone 2 make you faster?
• Should all your runs be easy?
• Is high-intensity training necessary?
• How much Zone 2 is too much?
• What’s the best balance of easy vs. hard training?

This episode will help you understand how to structure your training for performance, longevity, and sustainable progress.

Whether you're building your aerobic base, chasing a PR, or trying to improve your running economy, this conversation will help you train with more clarity and intention.

🎧 Topics Covered:

• What Zone 2 training actually means

• Aerobic base vs. speed development

• Mitochondrial adaptations explained

• Polarized training (80/20 method)

• VO₂ max and lactate threshold training

• When Zone 2 is essential — and when it’s not enough

Train smarter. Recover better. Perform at your best.

Train with intention on the Commit App 📌

Can you train endurance without losing strength, power, or muscle? In this episode we bust myths and break down the science behind concurrent training — showing how strength and endurance can coexist when programmed smartly. This is not about marathon training, or long-distance running in general, but about making running and strength exist together.

You’ll learn:

• How the interference effect works — and what research actually says about mixing running and lifting

• Why training order matters for strength outcomes when resistance and endurance workouts are combined

• Evidence that well-designed concurrent programs can still build strength and endurance without compromise

• Practical strategies for scheduling runs and lifts so they support, not sabotage, each other

Whether you’re a strength athlete wanting better conditioning or an endurance athlete lifting for performance, this episode gives science-based solutions — no PhD required.

Run and Lift better on the Commit App.

Ask your coach series! Cold-weather running, knee pain during training, strength splits, carb loading — how do you know what actually works? In this episode of the Performance Podcast, we break down the science behind common training challenges. Learn why breathing is harder in freezing temps, how to manage knee pain safely, the pros and cons of full-body vs upper/lower strength splits, and the evidence-based way to carb load before a key race.

Perfect for runners, lifters, and performance athletes, this episode gives you actionable insights to train smarter, recover better, and hit your goals with confidence.

Train on commit, turn knowledge into consistent results with strength training and running.
