About this episode
Brad Currier discusses mitochondrial decline and its impact on energy and recovery for women over 40, along with actionable strategies to improve mitochondrial health.

If you want to train hard, recover well, and feel genuinely energetic into your 40s and beyond, this one is worth your full attention.
