From Burnout to Strong Again: Tamsey Smith on RED-S, Running & Rebuilding in Your 40s

Tamsey Smith has loved movement her entire life! But even with decades of experience in the fitness industry, she found herself facing something many women are never warned about: low energy availability (LEA) and RED-S.

In this episode, Tamsey shares her journey from lifelong athlete and fitness professional to navigating underfueling, burnout, and ultimately rebuilding her strength in her 40s.

We talk about what happens when your love for movement outpaces your fueling… and how to find your way back.

Inside this conversation:

• What LEA and RED-S can look like in real life (even for experienced athletes)

• How underfueling impacts performance, recovery, and overall health

• The mindset shift from “doing more” to actually supporting your body

• Rebuilding strength, energy, and confidence in midlife

• How Tamsey balances running, teaching, and training without burning out

• Why running is still her first love & real life tips on how she eats enough

This episode is a powerful reminder that being disciplined isn’t the same as being well-fueled… and that it’s never too late to rebuild.
