NEUROSURGEON: You're NEVER Too Old To Build Strength & Lift Weights (with Dr. Betsy Grunch aka ladyspinedoc)

Can you still build serious muscle, increase bone density, and lift weights in your 40s, 50s, 60s, and beyond? A neurosurgeon says YES.

In this powerful episode, I sit down with neurosurgeon and spine specialist Dr. Betsy Grunch to crush the biggest myth about aging: that decline is inevitable. You might have seen Dr. Grunch recently on the Mel Robbins Show. In this episode she shares her expert perspective on why strength training is vital for long-term health, spinal support, and preventing injuries.

We discuss:

- The essential connection between muscle and bone density (especially for women).
- How to pivot after injury and the myth that pain equals damage.
- The "1% changes" you can make to protect your energy and time.
- Shifting from reactive to proactive health habits.
- Why rest is non-negotiable and how to set better boundaries.

Dr. Grunch is truly redefining what "strong" means...it's about flexibility, consistency, and owning your journey as the CEO of your own body. Tune in for the advice you need to feel empowered at any age!
