Protein, Progress and Protecting Your Muscle as You Age with Liz Plosser
 

I’m excited to welcome Liz Plosser to the podcast today!

Liz has worked in health and media for years, from Self Magazine to stepping into her own brand to help women get stronger, healthier, and more empowered. She’s a mom, she’s been through the journey herself, and she gets it - especially the protein struggle we ALL deal with!

In today’s episode, we dive deep into essential amino acids (EAAs), and why they’re such a game-changer for women. If you’re wondering WHY you may need these, think: better recovery, stronger hair and nails, improved muscle maintenance, and even brain function. 

We both use EAAs in our everyday routine; they’re kind of like your body’s “unsung hero”, and help to fill in the gaps (even if you’re doing pretty well with your protein AND overall nutrition)!

This episode is your reminder that being strong isn’t about perfection - it’s about showing up, learning what your body needs, and giving yourself the tools to feel amazing at EVERY stage of life!!
