Making Muscle Memories is a biomechanics-driven strength podcast for adults over 50 who feel their bodies changing and want a safe way to stay strong, capable, and independent.

Hosted by Lauren Eirk, a muscle and biomechanics specialist with over 40 years of experience, this podcast takes a different approach to fitness and aging.

Instead of chasing intensity, burning calories, or following generic programs, you’ll learn how to:

• Rebuild muscle strength in a way that supports your joints
• Reduce pain by improving how your body functions
• Restore confidence in how your body moves
• Understand why traditional approaches often lead to injury
• Train with structure, purpose, and long-term progression

Each episode blends personal stories, real-life experiences, and practical teaching to help you better understand your body and what it truly needs as you age.

    In this episode of Making Muscle Memories, Lauren Eirk shares three essentials for building a stronger core, with practical examples from yoga, Pilates, and resistance training. Discover why getting into a position doesn’t always mean you’re strong there, why control matters, and how resistance changes which muscles you challenge.

    Plus, a bonus principle to help you maintain the strength you build throughout your life.

    You feel better after an injury. But what happens next?

    ABOUT THIS EPISODE:
    You finished physical therapy. The pain has eased. You’re ready to get back to the activities you love. But there’s a part of injury recovery that nobody seems to prepare you for.

    In this episode of Making Muscle Memories, I share the story of a young volleyball player after knee surgery, along with lessons from my own injuries. We’ll explore why feeling better may not tell the whole story—and what it means to care for your muscles long after an injury.

  • 5th Exercise Rule to Break After 50: Some Exercises Are Just for “Old People"
    Sep 28 2026

    Send us Fan Mail

    Who decided that's an "old person" exercise?

    Have you ever looked at a chair exercise, a shorter range of motion, or a lighter weight and thought, “I’m not old enough to need that”?

    I used to judge exercises by how they looked, too. After years of working with people through injuries—and getting older myself—I see them differently. A chair can give you the support to challenge a muscle more precisely. Slowing down can reveal where you need more control. Adjusting an exercise can help you keep training consistently.

    The question isn’t whether an exercise looks impressive. It’s whether it helps your muscles meet the challenge you need today.

    In the final episode of my Exercise Rules to Break After 50 series, I’m sharing why we need to retire the “old people exercise” label—and what to focus on if you want to keep exercising for life.

    What exercise have you dismissed because of how it looked? Tell me in the comments. 👇
