Do You Really Need Weights While on GLP-1s? The Truth from Our Portland Maine Performance Fitness Studio

Evan Amell • April 20, 2026

If you’ve been scrolling through your feed lately or chatting with friends at a coffee shop in the Old Port, you’ve probably heard the buzz. GLP-1 medications like Ozempic, Wegovy, and Zepbound are changing the game for weight loss. For many people in our Portland community, especially those of us over 40, these medications feel like a long-awaited breath of fresh air.


Finally, the "food noise" is gone. Finally, the scale is moving in the right direction. It feels like a superpower, right?


But here’s the thing... there’s a conversation happening in the background that you might be missing. It’s a conversation about what happens underneath the weight loss. Because while the scale is going down, we need to make sure you aren't losing the very thing that keeps you strong, mobile, and metabolically healthy.


I’m talking about your muscle.


At EA Fitness & Performance, we’re seeing more and more of our members navigating the journey of GLP-1s. And the question I get asked most often is: "Evan, do I really need to lift weights if the medication is already doing the work?"


The short answer? Yes. Now more than ever.


Let’s dive into why strength training isn't just a "nice to have" when you're on these medications, it’s actually your insurance policy for a healthy, vibrant life.

The "Muscle Tax" You Didn't Sign Up For

When you lose weight rapidly, which is exactly what happens for many people on GLP-1s, your body doesn't just burn through fat stores. It looks for energy anywhere it can find it. Unfortunately, that often means it starts breaking down your lean muscle mass.


Research is starting to show some pretty eye-opening numbers. Without resistance training, anywhere from 20% to 50% of the weight lost on these medications can come from muscle rather than fat. 📉


Think about that for a second. If you lose 40 pounds, but 20 of those pounds are muscle... you haven't just gotten "smaller." You’ve actually changed your body composition in a way that could leave you weaker and more prone to injury. This is what people often call being "skinny fat." You look different in clothes, but your metabolism is actually slower than it was before.

Why Muscle is Your Metabolic Engine

Think of your muscle as the engine in your car. The more muscle you have, the bigger the engine, and the more fuel (calories) you burn, even when you’re just sitting on the couch watching a show or working at your desk.


When you lose muscle, you’re essentially shrinking your engine.


This becomes a huge problem if or when you ever decide to transition off the medication. If your engine is smaller, your body requires fewer calories to maintain its weight. This is a recipe for the "yo-yo" effect we all dread.


By prioritizing personal training or small group training while you're on these meds, you're sending a loud and clear signal to your body: "Hey! I'm using these muscles. Do not burn them for fuel! Keep them right where they are."


✅ The Benefit: You preserve your metabolic rate.

✅ The Result: Long-term weight maintenance becomes much, much easier.

The 40+ Factor: Bone Density and Balance

For our demographic, those of us over 40, muscle isn't just about looking good in a t-shirt (though that’s a nice perk). It’s about longevity.


As we age, we naturally start to lose muscle mass (sarcopenia) and bone density. If you add rapid weight loss from a GLP-1 to that natural aging process without doing any strength work, you’re doubling down on the risk.


Strength training is the "fountain of youth" for your bones. When you lift weights, you aren't just stressing your muscles; you’re putting healthy stress on your bones, which signals them to stay dense and strong.


At our Portland Maine performance fitness studio, we focus heavily on functional movements that keep you capable. We want you to be able to hike Tumbledown, carry all the groceries in one trip, and play with your grandkids without worrying about your back giving out.

Does Strength Training Make You Hungrier?

One of the biggest fears people have when starting an exercise routine while on GLP-1s is that they’ll get "runger", that intense hunger that comes after a long cardio session.


Here’s the good news: Strength training doesn’t usually stimulate the appetite the way intense cardio does.


In fact, research shows that resistance exercise is the perfect partner for GLP-1 medications because it helps you protect your health without working against the appetite-suppression benefits of the drug.


Stop thinking you need to spend hours on a treadmill. You don't. In fact, we’d rather see you spend 45 minutes moving some weights with intention.

The "EA Fitness" Strategy for GLP-1 Success

If you’re in the Portland area and you’re on this journey, you’re not alone. We’ve designed our programs at EA Fitness & Performance to meet you exactly where you are. We’re not a "big box" gym where you’re just a number. We’re a community.



Here is how we help our members on GLP-1s optimize their results:

  1. Protein-First Focus: We work with you through nutrition coaching to make sure you're getting enough protein. When your appetite is low, every bite counts. Protein is the building block that allows those lifting sessions to actually "stick."
  2. Smart Programming: You don't need to be a bodybuilder. You need a program that focuses on compound movements, squats, hinges, pushes, and pulls. Our coaches make sure your form is perfect so you stay injury-free.
  3. Recovery Monitoring: GLP-1s can sometimes make you feel a bit fatigued as your body adjusts. We listen. We adjust the intensity. We make sure you’re leaving the studio feeling energized, not drained.
  4. Community Support: There is something powerful about lifting next to someone who is on a similar path.

Common Questions I Get (The FAQ)

"What if I'm too tired to workout?"
It’s common to feel a little low energy when you first start these medications. Our advice? Start small. Even two 30-minute sessions a week can make a massive difference in muscle preservation. Often, once you get moving, that fatigue starts to lift.



"I don't want to get bulky; I just want to lose weight."
Trust me, you won't wake up as a pro bodybuilder by accident. Especially in a calorie deficit, "bulking" is nearly impossible. What you will do is get toned, firm, and strong.


"Can I just do walking?"
Walking is amazing. We love walking! Please keep walking around Back Cove or through the Eastern Promenade. But walking isn't enough to stop muscle wasting during rapid weight loss. You need resistance. You need to pick up something heavy.

Your Next Steps

Look, taking the step to improve your health with the help of a GLP-1 is a big deal. It shows you’re committed to a change. But don't let the scale be the only metric of your success.


How you feel, how you move, and how much muscle you keep will determine your quality of life five, ten, and twenty years from now.


If you're feeling a bit lost or worried about how to start, come talk to us. You can meet with me, Evan Amell, or any of our expert team members like Andrew Goyet or Isaac Wilkins. We’ll sit down, talk about your goals, and figure out a plan that supports your medication, your body, and your lifestyle.


You've got the tool (the medication). Now, let's build the foundation (the muscle).

The Reticular Activating System: The Brain Hack That Can Change Your Fitness Journey Have you ever bought a new car and then suddenly noticed that same make and model everywhere? It probably didn’t appear overnight. You simply started noticing it. That’s your brain at work. A similar process can happen when you set a clear fitness goal. Suddenly, you may notice the extra time in your schedule, the healthier choice at lunch, the opportunity to take a walk, or the strength you didn’t realize you still had. This is where the reticular activating system , or RAS , comes in. And no, it’s not a magic switch that guarantees results. But understanding how your brain filters information can help you change what you notice, what you focus on, and how you respond throughout your fitness journey. Especially after 40. Because if you feel stuck, unmotivated, or frustrated that you’ve “failed” at fitness before, you’re not alone. Your challenge may not be a lack of willpower. You may simply need a clearer target and better support around you. Let’s talk about how to create both. 🧠 What Is the Reticular Activation System? In simple terms, the RAS is part of your brain’s attention and alertness network. It helps regulate wakefulness and plays a role in deciding which information deserves your attention. Your brain receives an overwhelming amount of sensory input every moment: sounds, sights, conversations, movement, thoughts, and signals from your body. You can’t consciously process all of it. So your brain uses filters. The RAS helps determine what gets brought forward and what fades into the background. Think of it like a security guard at the entrance of a very busy building. Thousands of people may be trying to enter, but only certain information gets waved through as important. Your goals, beliefs, habits, and surroundings influence what your brain treats as important. That’s why you notice your new car everywhere. And it’s why a clearly defined fitness goal can change your awareness. If your goal is simply “get in shape,” that target may be too vague. Your brain doesn’t have enough direction. But if your goal is: > “I will complete three strength workouts each week for the next eight weeks so I can feel stronger carrying groceries and playing with my grandchildren,” you’ve given your brain something specific to look for. Now what about you? What would your brain notice if your goal were clear enough? Why You May Be Missing Fitness Opportunities Many people don’t struggle because fitness opportunities don’t exist. They struggle because those opportunities aren’t being filtered as important. You may walk past the gym without considering it. You may have a free 30-minute window but spend it scrolling because movement wasn’t part of your mental priority list. You may feel tired and automatically assume that means you can’t train. Your brain often follows the story you repeat. If you tell yourself: “I’m too old to get strong.” “I never stick with anything.” “I don’t have enough time.” “My body just doesn’t respond anymore.” “I’ve already failed too many times.” your attention may begin collecting evidence to support those statements. Stop.  That doesn’t mean your challenges aren’t real. Work, family responsibilities, old injuries, stress, and changing recovery needs can all make fitness more complicated after 40. But your current circumstances don’t have to become your permanent identity. A more useful statement might be: > “I’m learning how to train in a way that fits my body and my life now.” That shift matters. Your goal isn’t to pretend everything is easy. Your goal is to help your brain notice the next useful step. How to Program Your RAS for a Better Fitness Journey You can’t flip a switch and rewire your brain in one afternoon. But you can repeatedly direct your attention. Over time, that makes fitness-related choices, cues, and opportunities easier to recognize. Here are five practical ways to get started. 1. Write a specific goal “Get healthier” is a meaningful desire, but it’s not a clear target. Make it more specific. Try answering: What do you want to improve? How often will you take action? When will you begin? Why does this matter to you? How will you know you’re making progress? For example: > “I will complete two small group training sessions and one walk each week for the next month so I can improve my strength, energy, and confidence.” That goal gives your brain clear signals. You may begin noticing available class times, open spaces in your schedule, comfortable walking routes, or small choices that support your plan. Write it down. Keep it visible. Review it regularly. Your brain needs a target. 2. Visualize the process: not just the outcome Visualization works best when it helps you mentally rehearse the steps you need to take. Don’t only imagine a future version of yourself. Picture what happens today. Spend 30 to 60 seconds imagining: Putting on your workout clothes Walking into your training session Completing your warm-up Performing each exercise with good form Asking your coach for help when you need it Finishing the workout feeling proud that you showed up This makes the process more familiar. And when something feels familiar, it often feels more approachable. You don’t have to visualize a perfect workout. You only need to picture yourself beginning. 3. Use positive statements that feel believable Affirmations aren’t magic spells. They work best as reminders that direct your attention toward the person you’re becoming and the actions you’re willing to take. Try statements such as: “I am capable of getting stronger at my current age.” “I keep promises to myself through small, consistent actions.” “I notice opportunities to move throughout my day.” “I can train intelligently without needing to punish myself.” “Progress matters more than perfection.” Choose one that feels encouraging but believable. Then connect it to an action. Say, “I’m someone who takes care of my body,” while filling your water bottle or putting your gym bag by the door. The statement becomes more powerful when your behavior supports it. 4. Focus on progress instead of perfection Your brain will notice what you repeatedly measure. If you only measure body weight or appearance, you may overlook important wins. What else could count as progress? ✅ You lifted a little more than last month. ✅ You moved with less stiffness. ✅ You recovered well after training. ✅ You made a balanced meal during a busy week. ✅ You attended your session even though motivation was low. ✅ You felt more confident using an exercise that once intimidated you. Fitness after 40 should not be a daily test of how much discomfort you can tolerate. It should help you build strength, confidence, mobility, energy, and trust in your body. Look for those wins. Your brain will begin looking for more of them. 5. Surround yourself with helpful cues Your environment is always sending your brain messages. Make the healthy choice easier to notice and easier to begin. Try these simple changes: Put your gym clothes out the night before. Keep your training shoes where you’ll see them. Set a calendar reminder for your workout. Keep a water bottle on your desk. Place nourishing foods where they’re easy to reach. Write your weekly training schedule somewhere visible. Spend time with people who support your goals. Work with a coach who helps you stay accountable. This is one reason community matters so much. When you’re surrounded by people who are working toward their own goals, fitness becomes part of your normal environment: not something you have to force yourself to remember. At EA Fitness & Performance , personal attention and community work together. Your coach can help you create a plan that fits your experience, schedule, limitations, and goals. Our small group training sessions add structure, encouragement, and connection. You don’t have to do this alone. A Simple Daily R.A.S. Reset Try this five-minute routine each morning: Read your goal. Make sure it’s specific and connected to something meaningful. Visualize today’s action. Picture yourself starting and completing the next step. Repeat one supportive statement. Choose something realistic and encouraging. Identify one opportunity. Ask, “Where can I move, prepare, or make a better choice today?” Set up one cue. Put out your clothes, schedule your session, or prepare a healthy meal. That’s it. Small signals, repeated consistently, can help shift your attention. And when your attention changes, your choices often become easier to see. Your Brain Is Not the Enemy If you’ve struggled with fitness in the past, it’s easy to label yourself as lazy, inconsistent, or incapable. But your brain may simply be protecting familiar patterns. The good news? Familiar patterns can change. You can teach yourself to notice strength instead of limitation. Preparation instead of procrastination. Progress instead of failure. That doesn’t mean every day will be easy. Some days you’ll be tired. Some weeks will get disrupted. Life will happen. The goal is not perfection. The goal is to keep giving your brain a clear, supportive direction to follow. At EA Fitness & Performance, we help you turn that direction into a practical plan through personalized training , accountability, community, and nutrition coaching . You bring your starting point. We’ll help you build the next step. Ready to create a fitness target your brain can recognize: and your body can work toward? Get started with EA Fitness & Performance . You’re not starting over. You’re starting with more experience, more awareness, and a better understanding of what you need now. Keep going. Your next opportunity may already be there. You just need to notice it. 💪 : Evan
