Strength Training for Perimenopausal Women on GLP-1 Medications

I want to establish two things before we start.

First, I'm not a doctor. My background is in business, and I spent seven years as a CrossFit Level 1 Coach. More importantly, I have spent 30 years as a husband and father.

My wife is a strong woman, an executive, perimenopausal, and using a GLP-1 medication.

I watched the fitness industry struggle to give her useful answers.

Generic programs. Apps that didn't know she was in perimenopause. Training plans that couldn't account for days when medication side effects changed what she was capable of doing.

That experience eventually became part of the reason I built Salerna.

Second, GLP-1 medications work.

This isn't an argument against semaglutide, tirzepatide, or other GLP-1 medications. Decisions about whether these medications are appropriate belong between a patient and her healthcare provider.

The question I'm interested in is different:

What should training look like when a woman is navigating perimenopause and taking a medication that can substantially change appetite, body weight, energy, and food intake?

That's where fitness programming needs to get considerably smarter.

The Muscle-Mass Problem

There are two things worth understanding.

The first is aging.

Women, like men, gradually lose muscle mass as they age. The hormonal changes associated with the menopause transition add another layer of complexity to maintaining muscle, strength, and bone health.

The second is weight loss.

When someone loses a substantial amount of body weight, that weight does not come exclusively from body fat. Some lean tissue can be lost as well.

That matters for women using GLP-1 medications because these medications can produce substantial weight loss.

The goal shouldn't simply be to make the number on the scale smaller.

We should also be asking:

How much strength and lean mass are we preserving along the way?

For a woman simultaneously navigating the menopause transition, that becomes an especially important training question.

Fortunately, there is something we can do about it.

We can train.

Resistance Training Matters

Resistance training provides the body with a reason to retain and build muscle.

It also supports strength, physical function, and bone health — all things that become increasingly important as we age.

That doesn't mean every perimenopausal woman needs to become a powerlifter.

It means resistance training should be treated as a meaningful part of the health and fitness strategy rather than an optional addition after cardio.

And it needs to be progressive.

A weight that was challenging six months ago may no longer provide the same training stimulus today. Maintaining strength and muscle requires sufficient resistance and progression over time.

"Lift heavy" also needs some context.

Heavy is relative to the person.

For one woman, that might mean a barbell squat. For another, it might mean a challenging leg press, goblet squat, or bodyweight squat. There is no hierarchy here. The right exercise is the one that provides an appropriate challenge for you, given your experience, ability, equipment, and current capacity.

The objective isn't to hit an arbitrary percentage of a one-repetition maximum.

The objective is to provide an appropriate resistance-training stimulus that can progress as the person gets stronger.

GLP-1 Medications Change the Training Context

This is where generic programming starts to become a problem.

GLP-1 medications can be associated with side effects including nausea, vomiting, gastrointestinal discomfort, fatigue, and reduced appetite.

Those effects don't happen identically for every person or every day.

A woman may feel completely normal during one training session and considerably worse during another.

That creates a programming problem.

A static training plan assumes that today's capacity resembles the capacity the program predicted when it was written.

Sometimes it does.

Sometimes it doesn't.

Salerna approaches the problem differently.

Before training, we ask how you're actually doing.

How did you sleep?

How is your energy?

How sore are you?

How is your mood?

Are you experiencing symptoms or medication side effects that could affect today's training?

Those answers matter.

If today's capacity is lower, the workout should be able to change.

That might mean modifying volume, intensity, exercise selection, duration, or recovery.

And sometimes the right decision is recovery rather than training.

The objective isn't to force a workout at all costs.

It's to keep training productive and sustainable over time.

Protein Matters Too

Training provides the stimulus.

Nutrition provides the material the body needs to respond to it.

Protein is particularly important for active adults trying to maintain or build muscle.

This can become more difficult when appetite is substantially reduced.

If you're eating considerably less food, you have fewer opportunities to consume adequate protein and other essential nutrients. That makes the nutritional quality of what you do eat more important.

There isn't one universal protein target that is appropriate for every woman.

Body size, age, activity level, training volume, overall energy intake, health status, and individual goals all matter.

But if maintaining muscle is one of the objectives while losing substantial body weight, protein intake deserves deliberate attention.

For some women, that may simply mean prioritizing protein-rich foods.

For others, a protein supplement may be a practical way to help meet nutritional needs when appetite is limited.

If you're unsure what intake is appropriate for you — particularly if you have a medical condition or significant dietary restriction — a registered dietitian or other qualified healthcare professional can help establish an appropriate target.

Perimenopause Adds Another Layer

Perimenopause isn't one predictable physiological state.

Cycles can become irregular.

Sleep can change.

Some women experience hot flashes or night sweats. Others experience changes in mood, energy, joint comfort, or recovery.

Symptoms also vary enormously between women.

That's precisely why I don't think the answer is another rigid "menopause workout."

Two women can both be 48 and perimenopausal and arrive at the gym with completely different training capacity.

The label provides useful context.

It doesn't tell us everything we need to know.

The same is true of GLP-1 use.

Knowing that someone uses a GLP-1 medication matters.

Knowing how she is responding to it today matters more.

That's the Gap Salerna Was Built to Address

Most fitness personalization starts with questions like:

What's your goal?

What's your experience level?

What equipment do you have?

Those are useful questions.

They aren't enough.

Salerna considers a much broader set of inputs when determining what training should look like.

Life stage.

Daily readiness.

Symptoms.

Medication context when relevant to training.

Injuries and limitations.

Available equipment.

Training history.

Completed workouts.

And, when available, wearable data.

Those inputs feed a deterministic, rules-based training engine.

That distinction matters to us.

We're not asking a generative AI model to invent a workout based on a prompt. Salerna uses defined training logic and physiological context to determine how programming should change.

We can define the rules.

We can test them.

We can review them with experts.

And we can improve them as the evidence and our own data evolve.

That's the foundation Salerna is being built on.

What Should You Do?

Whether you use Salerna or not, there are a few principles worth taking seriously.

Make resistance training a priority.

Use resistance that is appropriately challenging for you and progressively increase the training stimulus as your strength and capacity improve.

Pay attention to protein and overall nutrition.

If a GLP-1 medication has substantially reduced your appetite or food intake, make sure weight loss isn't causing important nutritional needs to disappear from your diet along with the calories.

Don't confuse adaptation with failure.

Changing a workout because you're experiencing significant fatigue, nausea, poor sleep, pain, or another meaningful change in readiness isn't "giving up."

Sometimes reducing the session is appropriate.

Sometimes changing the exercise is appropriate.

Sometimes recovery is appropriate.

The goal is consistency over months and years, not winning one workout.

Talk to your healthcare team.

Your prescribing clinician should know about meaningful medication side effects and significant changes in your ability to eat, hydrate, exercise, or recover.

A registered dietitian can also help determine appropriate energy, protein, and nutrient intake during significant weight loss.

Training belongs alongside that care, not in competition with it.

Why This Matters

Weight loss is easy to measure.

You step on a scale and get a number.

Strength, muscle retention, physical capacity, and what your body will be capable of doing ten or twenty years from now are harder to see.

That doesn't make them less important.

For women navigating perimenopause while using GLP-1 medications, we should be thinking about both sides of the equation:

Lose what you want to lose while protecting what you want to keep.

That's a much better objective than weight loss alone.

And it's exactly the kind of problem adaptive training should be built to solve.

Built around your biology.

Frequently Asked Questions

Should women using GLP-1 medications strength train?

Resistance training can be an important part of maintaining strength, muscle, physical function, and bone health during weight loss.

The appropriate training program depends on your current health, training experience, physical limitations, medications, and other individual factors.

If you have concerns about exercising while taking a GLP-1 medication, discuss them with your prescribing healthcare professional.

Do women in perimenopause need to lift heavy weights?

Resistance training needs to provide enough challenge to create an appropriate training stimulus, but "heavy" is relative.

You don't need to perform maximal lifts or use a barbell to benefit from resistance training.

Machines, dumbbells, cables, resistance bands, and bodyweight exercises can all be useful depending on the person and the exercise.

The goal is appropriate resistance and progression — not chasing an arbitrary number.

Should I train when I'm experiencing GLP-1 side effects?

It depends on the symptoms and their severity.

Some days may only require modifying the duration, volume, intensity, or exercise selection.

Other situations may make recovery more appropriate.

Significant or persistent nausea, vomiting, dehydration, dizziness, inability to maintain adequate nutrition, or other concerning symptoms should be discussed with your healthcare provider.

Does Salerna change workouts because I'm taking a GLP-1 medication?

GLP-1 use provides Salerna with additional context.

Salerna does not assume that every person taking a GLP-1 medication needs the same training modification.

Instead, medication context is considered alongside daily readiness, symptoms, life stage, training history, injuries or limitations, available equipment, and other relevant information.

The objective is to respond to how the medication is affecting your training capacity rather than simply responding to the name of the medication.

How does Salerna approach perimenopause?

Perimenopause provides physiological context for training, but Salerna does not assume every perimenopausal woman should receive the same workout.

Programming considers life stage alongside daily readiness, symptoms, training history, available equipment, injuries or limitations, and other relevant inputs.

Supplement Considerations

Women navigating significant weight loss or changing nutritional needs may find that selected supplements make meeting certain nutritional requirements more practical.

Whey Protein Isolate

A protein supplement can be a convenient way to increase dietary protein intake when meeting protein needs through food alone is difficult.

Magnesium

Magnesium is an essential mineral involved in normal muscle and nerve function and numerous other physiological processes. Supplementation should account for dietary intake, individual needs, medications, and other relevant health considerations.

General Nutritional Support

Individual micronutrient needs vary considerably. Rather than assuming that perimenopause or GLP-1 use automatically requires a particular supplement, consider your overall dietary intake and discuss potential deficiencies or supplementation with an appropriate healthcare professional when necessary.
