Midlife Fitness, Fat Loss Myths & the Science of Training for Women with Alyssa Olenick, PhD

The Body Pod

Show Notes

In this episode of The Body Pod, Hailey sits down with Dr. Alyssa Olenick - exercise physiologist, researcher, endurance athlete, and one a trusted voice in women's fitness science. Alyssa holds a PhD in exercise physiology with an emphasis in women's fitness and has dedicated her career to translating complex science into real, actionable guidance for everyday women.

Hailey and Alyssa dig into the strength training conversation that midlife women actually need, cutting through the conflicting online noise to talk about what a smart training year really looks like, why training multiple characteristics (strength, power, and cardio) across a year produces far better results than doing the same thing indefinitely, and why power training and plyometrics are the most overlooked piece of the puzzle for women over 40. They also break down the cardio and heart rate zone conversation with refreshing honesty, explaining when zones actually matter, how to build an aerobic base, and why most women are overthinking it entirely.

The episode closes on the topic every midlife woman is asking about: metabolism, body composition, and the real story behind the changes happening in perimenopause and beyond. Alyssa unpacks what the research actually says about metabolic rate, fat redistribution, muscle loss, and why so many women feel like everything changed even when nothing in their routine did. She leaves listeners with a simple, grounded framework to stop spinning their wheels and start building a body (and a relationship with fitness) that actually works for this season of life.

If you've ever been told to stretch more, foam roll more, or simply "move better" to fix your pain, this episode may completely change how you think about injury recovery and long-term movement health.

Bryn Panee Burkhart came to Hailey Happens Fitness a little over a year ago, right in the middle of what she calls a full-blown sandwich generation smackdown. After a cross-country move to Hawaii, she was raising two kids, managing her father's cancer care and her aunt's dementia diagnosis, and quietly falling apart from exhaustion no one had a name for. It was not until she read an article on how women have been misled about menopause that she realized what she was actually dealing with was perimenopause, and it sent her down a research rabbit hole that eventually led her to strength training, hormone replacement therapy, and Hailey Happens Fitness.

Why does midlife suddenly bring on insecurity, self-sabotage, and a loss of self-confidence you never struggled with before? In this episode of The Body Pod, Hailey and Laura sit down with cognitive neuroscientist Dr. Caroline Leaf, bestselling author of 19 books on the mind-brain connection, to unpack exactly what happens in the midlife brain. Dr. Leaf explains why women in midlife shift from processing life in broad concepts to sudden, sharp detail, why this cognitive shift can surface a "midlife crisis," and how decades of unmanaged toxic thoughts quietly shape self-sabotage, anxiety, and stress well into your 40s, 50s, and beyond. If you've ever wondered why midlife hits differently for women's mental health and confidence, this conversation breaks down the neuroscience behind it.
