Strength training on GLP-1s can feel like a mystery wrapped in muscle soreness. You’re losing weight, but your arms still feel like spaghetti. You want to tone up, but the gym looks like a gladiator arena. And when you finally do manage a workout, you’re wiped for two days.
Sound familiar?
Here’s the thing: GLP-1 medications can help you lose weight, but without the right strength training tips, you could lose muscle right alongside it. And muscle is gold dust, it boosts your metabolism, shapes your body, and keeps you strong for the long haul.
This post will walk you through 10 easy, no-BS strength training tips tailored for women on GLP-1s. You’ll learn how to build muscle without burnout, fuel your workouts properly, and see real results (even if you’re just getting started).
Let’s lift like we mean it.
1. Ditch the Scale Obsession – Muscle Weighs More Than Fat
Let’s just get this one out the way: toning up doesn’t always mean dropping numbers on the scale.
In fact, when you’re building muscle and burning fat at the same time, the scale might barely budge, but your jeans will fit better, your arms will look tighter, and your energy will skyrocket.
Losing weight while gaining muscle is a game-changer, and GLP-1s give you the perfect window to make it happen, if you train smart.
2. Start Small with Resistance Bands or Light Dumbbells
You don’t need a massive barbell or a neon-lit gym to get started.
Grab a pair of dumbbells, a resistance band, or just your own bodyweight, and focus on compound exercises that hit your major muscles (think squats, push-ups, rows, and glute bridges).
If you’re new to lifting, check out my GLP-1 workout plan that’s plus-size friendly, no gym needed, and actually designed with your energy levels in mind.

3. Focus on Full Body (Not Just Arms) for Faster Results
I know we’re all here to “tone our arms,” but truthfully? Fat loss workouts that only target one body part don’t really work.
What does work? Strengthening your whole body to build lean muscle and crank up your calorie burn, even while you rest.
Full-body workouts that hit major muscles (like your legs, glutes, and back) will drive way more transformation than endless bicep curls alone.
4. Train Arms 2x a Week with Compound + Isolation Moves
If you want defined arms, the secret is consistency + variety. Aim for two strength workouts per week that include a mix of:
- Compound moves like push-ups, rows, and overhead presses
- Isolation moves like bicep curls and tricep kickbacks
Stick to this in your weekly workout plan, and you’ll be taking “GLP-1 before and after” pics with pride in no time.
5. Learn How Many Reps to Build Muscle (And When to Increase)
Confused about reps and sets? I go into a lot more detail about this in The GLP-1 Muscle Protection Program, but here’s a cheat sheet:
- 8-12 reps = muscle growth
- 12-15 reps = muscle endurance
- 4-8 reps = strength (for advanced lifters)
When the last few reps feel challenging but doable, you’re in the sweet spot. If it feels like a breeze? It’s time to go up a notch.
That’s how we build strength, and get serious workout results.

6. Don’t Skip Protein – It’s Non-Negotiable for Gains
Look, I know your appetite on GLP-1s can be a total diva, but muscle simply won’t grow without fuel. You need balanced meals with enough protein to support recovery and repair.
If you struggle with food in the mornings, try a GLP-1 meal plan with light options like:
- Protein shakes
- Greek yoghurt + chia
- Eggs with toast or rice cakes
- Cottage cheese with berries

7. Prioritise Recovery as Much as Reps
Muscle isn’t built in the workout, it’s built in the recovery. And if you’re pushing hard but skipping the rest, you’re short-changing your results.
Top recovery tips for GLP-1 users:
- Rest at least 1 day between strength sessions (you can do upper body one day, lower body the next – as long as you’re resting each area for 1 day)
- Get 7-9 hours of sleep
- Add magnesium and electrolytes if you’re feeling sore or drained
- Gentle stretching or mobility work helps speed things up

8. Track Your Workout Results – Not Just the Scale
Progress photos. How your clothes fit. How many push-ups you can now do. These are all real results, not just what the scale says.
Start keeping track of:
- What weights you’re using
- How many reps you hit
- Your mood + energy post-workout

9. Add Strength to Your Weekly Workout Plan for Better Fat Loss
Think of strength training as your fat burning workout’s best mate. Cardio helps you burn calories in the moment.
Strength helps you burn them all day long, even when you’re sat on the sofa with your feet up.
If you’ve been doing mostly walks or gentle movement, this is your invitation to level up.

10. Stay Consistent – Progress Happens When You Don’t Quit
You don’t need an advanced muscle building program to see changes, you just need to keep showing up. Whether that’s two strength workouts a week, or five, make it doable and stick with it.
And if you want a done-for-you plan that takes out all the guesswork? My simple 6-week GLP-1 Muscle Protection Program is designed to help you stay consistent, protect your muscle, and build real strength, without spending hours in the gym or collapsing on the sofa after.
