Ep 88: In this episode, Chelsey breaks down the science of Type I vs. Type II muscle fibers — and why most people never actually train the ones that matter most for longevity, strength, and athleticism.

You’ll learn:

• What Type I (slow-twitch) and Type II (fast-twitch) fibers actually do
• Why we start losing Type II fibers as we age — and how that impacts strength, power, and independence
• The difference between moving slowly and producing force quickly
• How to train your fast-twitch fibers with proper resistance training, not just cardio
• The link between fast-twitch muscle preservation and fall prevention, metabolism, and longevity

This episode will help you understand why building strong, powerful muscles isn’t just for athletes — it’s essential for everyone who wants to age well and move with confidence.
