5 Supplements That Improve Endurance

Being muscular doesn’t automatically mean being healthy.

In this deep-dive episode, we explore a counterintuitive but critical topic: why high muscle mass paired with low cardiovascular fitness can increase health risks rather than reduce them.

We unpack the research linking low VO₂ max to heart disease and early mortality, explain why muscle alone doesn’t protect the cardiovascular system, and explore the real-world consequences — from poor recovery to elevated blood pressure and chronic fatigue.

Using athlete comparisons, we show why hybrid fitness, strength and cardio, is the true sweet spot for performance, longevity, and quality of life.

If you care about living longer and performing better, this is a must-listen.

The Dangers of Lots of Muscle & Bad Cardio

Training is powerful, but it’s not magic.

In this episode, we explain why even the best training program can’t compensate for poor nutrition. We unpack the energy gap, how hormones influence fat loss, and why chronic stress and inflammation quietly sabotage results.

You’ll learn why diet quality impacts recovery, sleep, appetite, and body composition far more than most people expect, and why food is the lever that determines whether training actually works.

If you’re training consistently but not seeing progress, this conversation will clarify where the real bottleneck is.

Why You Can’t Out-Train a Bad Diet

Some of the most effective recovery strategies aren’t flashy, they’re simple, human, and often ignored.

In this episode, we cover four recovery methods that genuinely improve energy, performance, and long-term health, yet are rarely prioritised.

Extra sleep, true relaxation, reducing stimulant load, and doing absolutely nothing all play a bigger role than most people realise, especially for busy executives running on chronic stress.

If you’re training hard but still feel flat, wired, or exhausted, this episode will help you rethink what real recovery actually looks like.
