How Rucking Improves Blood Sugar and Insulin Sensitivity with Kayla Girgen

What does blood sugar actually mean for someone who rucks for fitness?

In this episode, registered dietitian and author Kayla Girgen joins The Rucker’s Edge to break down glucose, insulin, continuous glucose monitors (CGMs), and how movement directly improves metabolic health.

You’ll learn:

• What glucose really is and how your body uses it
• The role insulin plays in blood sugar regulation
• What insulin resistance actually means
• What CGMs measure — and who should consider using one
• Why post-meal movement dramatically improves blood sugar response
• How muscle mass impacts glucose disposal
• How rucking compares to walking, running, and strength training for metabolic health

Kayla explains how muscle acts like a sponge for circulating glucose and why building and preserving muscle is one of the most powerful long-term strategies for improving metabolic flexibility.

If you’ve ever wondered whether a CGM is worth trying or how rucking affects blood sugar, this episode gives you practical, actionable insight you can apply immediately.
