Zone 2 Training: Do Women Really Need It?

Zone 2 training—steady-state cardio at 60–70% of your max heart rate—has been hailed as essential for endurance, fat burning, and longevity. But does the research actually apply to women?

In this episode, Dr. Kelsy Vick, board-certified Doctor of Physical Therapy and pelvic floor PT, breaks down the science of Zone 2 training and its role in women’s health, metabolism, and recovery. We’ll cover:

  • What Zone 2 training really is (and how to calculate it)
  • The cardiovascular and metabolic benefits for women
  • Hidden downsides: time inefficiency, cortisol stress, and limited bone/muscle benefits
  • Why women already have a natural advantage in fat oxidation and mitochondrial function
  • HIIT, SIT, and polarized training vs Zone 2—what’s more effective?
  • How to fit Zone 2 into your routine without guilt

If you’ve ever wondered whether you need 45–90 minutes of Zone 2 cardio five times a week, or if HIIT and strength training might be more efficient, this episode clears the air.

Tune in to learn how Zone 2 fits into your exercise handbag—and why it might be more of an accessory than an essential for women’s fitness.
