Personal Training While Taking a GLP-1: Why Strength Training Matters During Weight Loss

GLP-1 medications have changed the conversation around weight loss.

But if you're losing weight while taking a GLP-1 medication, there's another part of the conversation I don't want you to overlook:

Strength.

I'm Neely, owner of Sweat Society Fitness in Hillcrest, San Diego. As a personal trainer, I work with clients who aren't simply trying to make the number on the scale go down.

We want your body to become stronger, more capable, and better prepared for everyday life.

If you're taking a GLP-1 medication under the care of a healthcare provider, exercise—particularly resistance training—may be an important part of your overall fitness plan.

This article isn't medical advice, and decisions about GLP-1 medications should always be discussed with your prescribing healthcare professional.

What I can help with is the fitness side of the equation.

What Are GLP-1 Medications?

GLP-1 medications are prescription medications used for conditions including type 2 diabetes and, in some cases, chronic weight management.

Depending on the medication and indication, you may recognize names such as semaglutide or tirzepatide.

Your physician or other qualified healthcare provider should determine whether a medication is appropriate for you and provide guidance regarding treatment.

As a personal trainer, I'm not here to manage your medication.

My role is different.

I'm interested in what happens when you say:

“I'm losing weight. Now how do I get stronger?”

That's where personal training and resistance exercise enter the conversation.

Why Strength Training Matters During Weight Loss

When people pursue weight loss, it's easy to become completely focused on one measurement:

Body weight.

But losing weight and becoming stronger aren't the same goal.

If you're losing a significant amount of weight, preserving your physical capabilities and supporting muscle becomes an important consideration.

That's one reason resistance training deserves a place in the conversation.

Rather than making your entire goal:

“I want to weigh less,”

I encourage clients to also think:

“I want to become stronger.”

“I want to maintain my ability to do everyday activities.”

“I want to feel capable in my body.”

Those are meaningful measures of progress too.

Can You Strength Train While Taking a GLP-1?

For many people, resistance training can be part of an exercise program while using a GLP-1 medication, but your individual situation matters.

Your prescribing healthcare provider should advise you about any medical considerations or exercise restrictions that apply to you.

Once you're cleared to exercise, your strength program can be designed around your:

• Current fitness level

• Training experience

• Goals

• Energy level

• Exercise history

• Previous injuries

• Other physical activity

You don't need to jump into an extreme workout program simply because you're motivated to make changes.

Start where you are and build from there.

Your Workout Doesn't Need to Be Extreme

One mistake I see people make with weight loss is assuming more is always better.

More cardio.

More workouts.

More intensity.

More calories burned.

But a good fitness program isn't punishment for what you ate, and exercise doesn't have to leave you completely exhausted to be worthwhile.

If you're beginning strength training, we may start with basic movement patterns such as:

• Squats

• Hinges

• Pushes

• Pulls

• Carries

• Core exercises

• Balance work

From there, we can gradually increase the challenge as your strength and confidence improve.

Think Beyond the Scale

This is especially important during a weight-loss journey.

The scale gives you information.

It doesn't give you the whole story.

I also want clients to notice things like:

Are you getting stronger?

Can you lift more than you could a month ago?

Do everyday activities feel easier?

Are you becoming more consistent?

Do you feel more confident using weights?

Can you perform exercises that once intimidated you?

These are all forms of progress.

Your fitness journey doesn't need to become a race toward the lowest possible number on the scale.

Why Muscle Matters as You Get Older

Strength training becomes particularly relevant for adults in their 40s, 50s, 60s and beyond.

Your goals may begin shifting away from simply trying to “burn calories” toward maintaining a strong and capable body.

You might care more about:

• Maintaining strength

• Staying active

• Supporting healthy aging

• Being able to travel

• Carrying groceries

• Getting up from the floor

• Hiking

• Playing with your children or grandchildren

• Continuing activities you enjoy

That's why I encourage clients to think about what they want their bodies to do, not only what they want their bodies to weigh.

GLP-1 Weight Loss and Women Over 40

Women in their 40s, 50s and 60s may be thinking about several things at once:

• Weight

• Strength

• Body composition

• Menopause or perimenopause

• Energy

• Healthy aging

• Previous injuries

• Lifestyle changes

Instead of treating each one as a completely separate issue, I prefer to look at the bigger picture.

Your workout program should make sense for your current body, lifestyle, and goals.

What if You've Never Lifted Weights Before?

That's okay.

You don't need previous strength-training experience to begin.

And you definitely don't need to “get fit” before hiring a personal trainer.

Your starting point is simply your starting point.

A beginner program might focus first on:

• Learning proper technique

• Understanding basic exercises

• Finding appropriate resistance

• Becoming comfortable with equipment

• Building consistency

• Gradually increasing the challenge

You don't need to prove anything during your first workout.

You need to learn.

If you're nervous about starting, here's What to Expect During Your First Personal Training Session.

What if Your Energy Feels Different?

This is something to discuss with your healthcare provider, particularly if you experience significant fatigue, dizziness, weakness, dehydration, gastrointestinal symptoms, or anything else concerning after starting a medication.

From a training perspective, your workouts don't have to be identical every day.

Your trainer can adjust things such as:

• Exercise selection

• Resistance

• Number of sets

• Number of repetitions

• Rest periods

• Overall training volume

Your program should be challenging enough to encourage progress without assuming that every workout has to be your hardest workout.

Don't Forget About Nutrition

When you're focused on weight loss, it can be tempting to think that eating as little as possible will produce the best result.

That's not a fitness strategy I recommend.

Your body still needs adequate nutrition to support your daily life and training.

Your individual nutritional needs should be discussed with an appropriate healthcare or nutrition professional, particularly when you're taking a prescription medication.

At Sweat Society Fitness, nutrition is approached as part of a broader wellness picture rather than a punishment-and-restriction cycle.

You can learn more about Nutrition and Wellness Coaching.

Cardio vs. Strength Training While Losing Weight

This doesn't have to be an either/or decision.

Cardiovascular exercise and resistance training accomplish different things and can coexist in the same fitness program.

You might:

• Strength train

• Walk regularly

• Hike

• Cycle

• Swim

• Take a fitness class

• Participate in recreational activities

The exact combination depends on your goals and abilities.

But if all of your exercise is centered around burning as many calories as possible, I'd encourage you to broaden the goal.

Give yourself an opportunity to become stronger too.

How Often Should You Strength Train?

There isn't one training frequency that's right for everyone.

It depends on factors including:

• Your goals

• Training experience

• Schedule

• Recovery

• Other exercise

• Health considerations

• Ability to train independently

Some people work with a personal trainer once per week and complete additional workouts independently.

Others benefit from more frequent sessions.

You can read How Often Should You Work With a Personal Trainer? for a more detailed explanation.

Can Personal Training Help During a GLP-1 Weight-Loss Journey?

Personal training can provide something medication doesn't:

A progressive exercise program designed to help you become stronger.

A personal trainer can help you:

• Learn strength exercises

• Improve exercise technique

• Select appropriate resistance

• Progress exercises

• Stay accountable

• Track strength improvements

• Build an exercise routine

• Become more confident training

Medication and personal training have very different roles.

Your prescribing healthcare provider manages your medication.

Your trainer helps you build your fitness.

What if You Have Old Injuries?

Having an old injury doesn't automatically exclude you from strength training.

But the details matter.

If you have a new injury, unexplained symptoms, significant pain, or a medical condition that affects exercise, speak with an appropriate healthcare professional first.

Once you're cleared to exercise, your trainer can modify your program based on your current abilities.

That might mean changing:

• Range of motion

• Exercise selection

• Resistance

• Position

• Volume

• Progression

What if You've Lost Weight but Still Don't Feel Strong?

This is exactly why I don't want the scale to be your only measure of success.

Weight loss doesn't automatically teach you how to squat.

It doesn't teach you how to lift.

It doesn't create an exercise routine.

And it doesn't automatically make you feel physically capable.

Those things require practice.

So if you've already lost weight but you're thinking:

“Okay, now I want to get strong,”

that's an excellent next goal.

You don't have to wait until you've reached a particular goal weight either.

With appropriate medical clearance, strength training can be part of the journey rather than something you save until the end.

Should You Hire a Personal Trainer While Taking a GLP-1?

You don't have to.

But working with a trainer may be useful if you:

• Don't know how to strength train

• Haven't exercised in years

• Want an individualized program

• Need accountability

• Are concerned about maintaining strength

• Want to track something besides body weight

• Have previous injuries

• Feel uncomfortable in a traditional gym

• Want help progressing your workouts

Strength Training During Weight Loss Should Have a Bigger Goal

Weight loss may be what gets you started.

But I want you to think beyond it.

What do you want to be able to do?

How strong do you want to feel?

What activities do you want to keep enjoying?

How do you want to feel walking into a gym?

What do you want your body to be capable of five or ten years from now?

Those questions can completely change the way you approach fitness.

Instead of exercise being something you do only to lose weight, it becomes something you do to build yourself up.

And that's a much more interesting goal.

Frequently Asked Questions

Should I strength train while taking a GLP-1 medication?

Resistance training may be appropriate as part of an overall exercise program, but your individual health circumstances matter. Talk with your prescribing healthcare professional about exercise considerations or restrictions specific to you.

Can you build muscle while taking a GLP-1?

Resistance training provides a stimulus that can support strength and muscle development, but individual results depend on many factors, including training, nutrition, recovery, health, age, and medication-related considerations.

No. A personal trainer isn't required. However, individualized coaching can be useful if you're new to strength training, want accountability, or aren't sure how to build and progress an exercise program.

Is cardio enough while taking a GLP-1?

Cardiovascular exercise and resistance training serve different purposes. Depending on your health and goals, an exercise program may incorporate both.

Don't simply push through concerning symptoms. Discuss significant or persistent fatigue, weakness, dizziness, dehydration, or other symptoms with your healthcare provider.

Can a personal trainer manage my GLP-1 medication or diet?

A personal trainer should stay within their professional scope. Medication decisions belong with your prescribing healthcare professional. Nutrition guidance should also remain appropriate to the trainer's qualifications and your individual healthcare needs.
