Next Level by Stacy T. Sims, PhD

Audiobook Summary and Review by StoryShots

Skip the fasted cardio.

Your body actually needs food before it can build anything.

Introduction

Everything you learned about exercise came from studies on men.

That is not a minor footnote.

It is the reason your workouts stopped working the moment your hormones shifted.

Next Level: Your Guide to Kicking Ass, Feeling Great, and Crushing Goals Through Menopause and Beyond, by Stacy T. Sims, PhD, exists to fix that gap.

Women are not small men.

Most fitness advice assumes a female body is just a smaller version of a male one.

Cut the calories, add more cardio, shrink the portions.

That assumption is why so many women hit perimenopause and watch their usual routine stop producing results, or start producing the opposite ones.

Female physiology runs on a different hormonal engine.

Estrogen and progesterone regulate insulin sensitivity, bone density, and stress response, not just reproductive cycles.

When those hormones decline, the old playbook of long runs and small meals actively works against you, raising cortisol and encouraging fat storage exactly where you do not want it.

If your workouts feel like they betrayed you overnight, they did.

The exercise science industry built its rulebook studying male bodies and assumed the female one would just follow along.

Understanding this shift matters more than any specific workout.

But knowing your hormones changed is only step one.

Lift heavy, then rest hard.

Once you accept your body runs differently now, the next question is what actually rebuilds it.

The instinct is more cardio, more hours.

That instinct is backward.

Brief, intense effort followed by full recovery does more for a menopausal body than hours of steady-state cardio ever could.

Sprint interval training, short bursts of all-out effort followed by real rest, triggers a hormonal response steady cardio does not, boosting growth hormone and counteracting the elevated cortisol that chronic cardio tends to worsen.

Heavy strength training matters even more.

Light weights for endless reps never send a strong enough signal to grow muscle.

Near-failure loads do.

If you have been doing more cardio and losing less fat, the workout was never the problem.

The intensity was.

But this only works if what you eat around those workouts matches what your body is asking for, and most women get that part backward.

The 30-minute window nobody told you about.

Skip the fasted cardio.

Your body actually needs food before it can build anything.

Fasted training feels virtuous.

It also spikes cortisol, drains blood sugar, and breaks down the very muscle you are trying to build.

Refuel within roughly 30 minutes after a workout, not the 90-minute window that works fine for men, and you shift your body out of a stress state and into a building one.

Protein needs rise sharply during this transition, not fall, because women stop using it as efficiently as they age.

Muscle mass, not leanness, predicts whether you outlive heart disease.

If this reframed how you think about training through menopause, someone in your life is probably white-knuckling their way through fasted workouts right now.

Send them this summary.

Final summary.

This summary of Next Level threads together the flawed male-centric science behind most fitness advice, the case for brief intense training over chronic cardio, and the precise fueling window that makes muscle-building possible, all pointing to one argument: work with your physiology, not against it.

Left uncovered are the full hormone therapy discussion, the specific macronutrient planning charts Stacy T. Sims built for different training phases, and the pelvic floor and bone density protocols that round out her complete framework.

Anyone training seriously through perimenopause or beyond needs those details, not just the philosophy.

We are putting together the full summary of Next Level right now, with an infographic and animated video.
