Can you lift weights while taking Mounjaro or Wegovy? Absolutely—and it might be one of the best things you can do.

As a woman, juggling work, family, and everyday life often leaves little time to focus on yourself, let alone your fitness goals. Weight loss can feel like an uphill battle—especially with the added challenge of managing appetite, energy levels, and cravings. If you're taking GLP-1 medications like Wegovy or Mounjaro to help regulate your blood sugar and suppress your appetite, you may be wondering, "How can I maximise these medications and actually see real results?"

The answer could lie in something as simple as strength training. While cardio often steals the spotlight when it comes to weight loss, strength training offers an incredible array of benefits that not only help you shed pounds but also reshape your body. It works synergistically with GLP-1 medications, boosting your metabolism, preserving lean muscle mass, and improving overall body composition.

Incorporating strength training into your GLP-1 weight loss plan doesn't just mean lifting weights—it means empowering yourself with a routine that supports long-term, sustainable results. Whether you're a beginner or already familiar with exercise, strength training offers a pathway to a stronger, more confident version of yourself. So, why not take the first step towards combining the power of GLP-1 with strength training for a transformation that goes beyond the scale? The journey to a healthier you starts with strength, both physically and mentally.

The Benefits of Strength Training

Strength training, also known as resistance training, is one of the most effective ways to build muscle mass and improve overall health. Unlike cardio exercises that primarily burn calories during the activity, strength training has long-term benefits by increasing muscle mass, which, in turn, enhances metabolism and helps with weight loss. 

1. Building Muscle Mass

Muscle mass is vital for achieving optimal health and weight management. Strength training exercises such as weightlifting, resistance bands, or bodyweight exercises (e.g., squats, lunges, and push-ups) stimulate muscle growth through a process called hypertrophy. When you lift weights, small tears occur in the muscle fibres, and as these fibres repair, they grow stronger and larger. Over time, this results in increased muscle mass.

A study found that a 12-week strength training program increased lean muscle mass by 1.5-2.0 kilograms in participants. This increase in muscle mass was accompanied by improvements in strength and physical function.

2. Boosting Metabolism and Burning Calories

One of the most significant benefits of strength training is its role in boosting metabolism. Muscle tissue is metabolically active, meaning it burns more calories even at rest compared to fat tissue. This helps to increase your overall calorie expenditure, even when you’re not working out.

A study showed that participants who engaged in strength training had an increase in resting metabolic rate (RMR), meaning they burned more calories throughout the day due to an increase in muscle mass. The study found that for every 1 kilogram of muscle gained, the body burns an extra 30-50 calories per day at rest, which can contribute to a significant amount of calorie expenditure over time.

3. Improving Body Composition

Body composition refers to the ratio of fat to lean tissue in the body. Strength training helps to improve body composition by decreasing body fat and increasing lean muscle mass. This not only enhances the appearance of the body but also improves overall metabolic health. A higher muscle-to-fat ratio is associated with better insulin sensitivity, improved blood sugar control, and a lower risk of chronic diseases like type 2 diabetes.

In a study on overweight and obese women who participated in strength training showed a significant decrease in body fat and an increase in lean muscle mass, which led to improved overall body composition and reduced the risk of metabolic syndrome. The results demonstrated that strength training was more effective in reducing fat mass than cardiovascular exercise alone.

4. Supporting Bone Health

As we age, bone density tends to decrease, which can lead to conditions like osteoporosis, especially in postmenopausal women. Strength training has been shown to be an effective method for maintaining or even increasing bone mineral density (BMD). By placing stress on the bones during strength training, it triggers the bone remodelling process, which strengthens the bones over time.

A meta-analysis found that resistance training significantly improved bone mineral density in postmenopausal women. The study concluded that strength training increased BMD by up to 2% in the spine and hip regions, which are common areas affected by osteoporosis. Additionally, a study showed that resistance training could help prevent the loss of bone mass, reducing the risk of fractures.

5. Enhancing Functional Fitness

Functional fitness refers to exercises that help improve everyday movements, such as bending, lifting, and carrying. Strength training enhances functional fitness by strengthening the muscles involved in daily activities, improving balance, posture, and coordination. This is particularly important for older adults, as it can help them maintain independence and reduce the risk of falls and injuries.

A study investigated the effects of strength training on older adults and found that participants who performed resistance exercises experienced improved muscle strength, balance, and overall functional fitness. The study showed that after 12 weeks of strength training, the participants’ ability to perform daily tasks like walking, standing, and carrying groceries significantly improved.

Getting Started with Strength Training

Starting a strength training routine is an exciting step toward better health and fitness. However, as with any new exercise program, it's important to approach it with care and consideration. In this section, we’ll explore key steps to take before starting strength training, whether you're heading to the gym or working out at home. By following these guidelines, you can ensure that you begin your strength training journey in a safe, effective, and enjoyable way.

1. Consult with a Healthcare Professional

Before embarking on any new fitness routine, especially strength training, it’s crucial to consult with a healthcare professional, particularly if you have any underlying health conditions such as heart disease, diabetes, joint problems, or obesity. A healthcare provider can assess your health status and offer guidance on the best exercise approach, ensuring that you avoid exercises that may aggravate any pre-existing conditions.

For example, those with joint issues like osteoarthritis may need to modify certain movements to avoid strain. In contrast, individuals with cardiovascular concerns should work with their healthcare provider to tailor an exercise routine that ensures a safe heart rate range during exercise. A study highlighted the importance of consulting a healthcare provider before starting a new exercise program, particularly for individuals with chronic conditions. The research found that structured exercise programs, including strength training, could reduce the severity of many chronic health conditions but must be done with medical guidance to prevent injury.

2. Choose a Suitable Gym or Home Workout

When deciding between a gym membership or a home workout setup, it's important to weigh the pros and cons of each option. A gym provides access to a variety of equipment and the guidance of qualified trainers, which can be particularly helpful for beginners. Trainers can help you learn proper form and technique, reducing the risk of injury and ensuring you get the most out of each exercise.

However, some individuals may prefer the convenience and privacy of working out at home. Home workouts can be just as effective, especially when you invest in a few key pieces of equipment like dumbbells, resistance bands, and a stability ball. Plus, home workouts can save on time and gym membership costs, making it easier to fit in workouts without leaving the house.

Tips:

  • If you choose a gym, look for one that offers a range of equipment suited to your needs, such as free weights, resistance machines, and functional training spaces.
  • If you choose to work out at home, start with a basic setup: a set of dumbbells, resistance bands, and a yoga mat can go a long way in helping you begin strength training safely and effectively.

A study found that both gym and home-based strength training routines resulted in similar improvements in muscle strength and endurance. The study concluded that the key to success is consistency and proper form, regardless of location.

3. Start Slowly and Gradually Increase Intensity

For beginners, it’s essential to start slow and build up gradually. Trying to lift heavy weights right away can increase the risk of injury and may lead to burnout. Start with lighter weights and fewer repetitions to focus on mastering form and technique. Gradually increase the intensity over time by adding more sets, repetitions, or weight. Progressive overload is a key principle in strength training. It involves gradually increasing the weight, repetitions, or intensity of your workouts to challenge your muscles, stimulate growth, and prevent plateaus. This process is vital for continued progress and improving strength and muscle mass.

If you're new to strength training, start with a full-body workout using light dumbbells or bodyweight exercises (e.g., squats, lunges, push-ups) for 2-3 sets of 8-10 repetitions. Over the next few weeks, increase the weight or number of repetitions as your body adapts to the workout. Research supports the concept of progressive overload, showing that gradual increases in weight and resistance are critical for continuous improvement. The study found that individuals who followed a progressive overload protocol saw greater increases in muscle mass and strength compared to those who did not adjust their exercise intensity.

Creating a Strength Training Routine

Creating a well-rounded strength training routine is crucial for achieving long-term fitness goals. Whether you're aiming to build muscle, increase strength, or improve overall health, it’s important to structure your workouts in a way that promotes muscle growth, recovery, and balanced fitness development. In this section, we'll break down the key components of a successful strength training routine, focusing on frequency, exercise selection, and how to structure your sets and repetitions based on your goals.

1. Frequency: Training 2-3 Times Per Week

When it comes to strength training, consistency is key—but so is rest. For beginners and intermediate lifters, it’s recommended to train 2-3 times per week, allowing at least 48 hours of rest between workouts for each muscle group. This rest period is essential for muscle recovery and growth, as muscles repair and rebuild during recovery phases.

Example:
A typical weekly routine might include full-body workouts on:

  • Monday
  • Wednesday
  • Friday

This schedule gives muscles time to recover between sessions, promoting effective muscle repair and preventing overtraining. For those with more advanced fitness levels, you might increase frequency to 4-5 times per week, but it's crucial to balance training different muscle groups to avoid fatigue and burnout. A study found that strength training 2-3 times per week maximised muscle gains and strength development for beginners. Additionally, muscle recovery is essential to avoid overuse injuries and promote long-term fitness improvements.

2. Exercise Selection - Compound and Isolation Exercises

A balanced workout routine should include both compound exercises and isolation exercises to target multiple muscle groups and promote balanced muscle development. Compound exercises are those that work multiple muscle groups at once. These exercises provide a functional and efficient way to build strength and muscle mass. Examples include:

  • Squats: Target the quadriceps, hamstrings, glutes, and core.
  • Lunges: Work the legs, glutes, and stabilising muscles.
  • Push-ups: Engage the chest, shoulders, triceps, and core.
  • Rows: Target the back, shoulders, and arms.

These exercises are crucial for building overall muscle mass and improving functional strength because they mimic movements used in daily life (e.g., lifting, bending, squatting).

Isolation exercises, on the other hand, focus on a single muscle group at a time. While they’re excellent for targeting specific muscles and addressing any imbalances, they should complement, not replace, compound exercises. Some examples of isolation exercises include:

  • Bicep curls: Target the biceps.
  • Tricep extensions: Focus on the triceps.
  • Leg curls: Isolate the hamstrings.

Incorporating a mix of both types of exercises into your routine ensures a balanced workout that promotes overall strength, muscle growth, and injury prevention. According to a study compound exercises lead to greater increases in strength and muscle mass compared to isolation exercises. However, the research also highlighted that isolation exercises are beneficial for correcting muscle imbalances and targeting specific areas for growth.

3. Reps and Sets: Tailoring Your Routine to Your Goals

The number of repetitions (reps) and sets you perform will depend on your fitness goals. Different rep ranges stimulate different adaptations in the body. Here’s a breakdown:

  • Strength Training: For those looking to maximise strength, lower rep ranges with heavier weights are typically used. Aim for:
    • Reps: 3-5
    • Sets: 4-6

Lifting heavier weights in this range stimulates the nervous system and increases strength by improving the efficiency of the muscles' ability to generate force.

  • Hypertrophy (Muscle Growth): If your goal is muscle growth (hypertrophy), aim for moderate reps and sets with moderate weight. This range allows for sufficient time under tension, promoting muscle enlargement. Ideal parameters include:
    • Reps: 6-12
    • Sets: 3-4

Research has shown that the hypertrophy rep range is the most effective for promoting muscle mass gains. The key is focusing on the muscle's time under tension during the lift, allowing for maximum fiber recruitment and growth.

If you're performing squats as a compound exercise for muscle growth:

  • Use a weight that allows you to complete 6-12 reps with good form (for hypertrophy).
  • Perform 3-4 sets, resting for about 90 seconds between sets for recovery.

A study confirmed that the 6-12 rep range is most effective for muscle hypertrophy. The study compared different rep ranges and found that moderate weights with higher rep ranges resulted in the greatest increase in muscle size compared to heavier loads with lower reps.

Considerations for Women on GLP-1 Medications

Strength training is an effective way to support weight loss and improve overall health. However, for women who are using GLP-1 medications like Wegovy or Mounjaro, there are specific considerations to keep in mind to ensure a safe and effective workout experience. GLP-1 medications, while offering tremendous benefits for appetite regulation and weight management, can impact hydration levels, muscle recovery, and overall energy. Here, we explore key considerations to help women on GLP-1 medications maximise their workout routines and support muscle growth while maintaining health and well-being.

1. Hydration: Staying Hydrated is Essential

One of the most important considerations for individuals using GLP-1 medications is staying well-hydrated, particularly during and after exercise. GLP-1 medications can cause gastrointestinal side effects such as nausea, vomiting, and diarrhoea, which can lead to dehydration. Additionally, the body may require more water during physical exertion to maintain optimal performance and recovery.

Dehydration can negatively affect strength, endurance, and muscle recovery. It can also impair your body’s ability to regulate blood sugar, which is crucial for those on GLP-1 medications, especially if you’re managing diabetes. The risk of dehydration is heightened during exercise, as the body loses fluids through sweat, so it’s important to increase your fluid intake to compensate for these losses.

Practical Tips:

  • Drink water throughout the day, not just during workouts.
  • Keep a water bottle nearby during exercise, and aim to drink 8-10 ounces of water every 20-30 minutes of exercise.
  • Rehydrate after your workout with water or an electrolyte solution, especially if you’ve been sweating heavily.

A study found that dehydration could exacerbate side effects of GLP-1 medications and reduce exercise performance. Staying hydrated is essential for muscle function and overall energy levels, particularly when using medications that affect fluid balance.

2. Listening to Your Body: Avoiding Overtraining

It’s important to recognize the potential impact of GLP-1 medications on your energy levels and adjust your workout routine accordingly. While these medications can help with appetite suppression and weight management, they may also affect your overall energy and stamina, especially when you’re starting out. Overtraining, or pushing your body too hard without adequate recovery, can lead to fatigue, injuries, and a plateau in your progress.

Practical Tips:

  • Pay attention to how your body feels before, during, and after exercise. If you're feeling fatigued or lightheaded, it may be a sign that you need to rest or adjust the intensity of your workouts.
  • Incorporate rest days into your routine to allow your muscles to recover and rebuild. Muscles grow stronger during periods of rest, not during the workout itself.
  • Start with lighter weights and lower intensity, gradually increasing intensity as your body adapts.

A clinical study emphasises the importance of progressive overload, which is increasing intensity over time. However, it also stresses the necessity of adequate rest to avoid burnout, especially for individuals on medications that affect metabolism and energy levels.

Consulting with a Registered Dietitian - Fueling Muscle Growth and Recovery

Nutrition plays a key role in strength training and muscle recovery, and women on GLP-1 medications should consider consulting with a registered dietitian to ensure they’re meeting their dietary needs. GLP-1 medications often lead to reduced appetite, which can make it more challenging to consume sufficient calories and protein to support muscle growth and recovery.

A registered dietitian can help create a personalised nutrition plan that focuses on the right balance of macronutrients (proteins, fats, and carbohydrates) and micronutrients (vitamins and minerals) to support your fitness goals. Protein, in particular, is essential for muscle repair and growth, so ensuring adequate protein intake is a priority.

A study highlighted that adequate protein intake, combined with strength training, is critical for promoting muscle hypertrophy. For women on GLP-1 medications, ensuring a balanced diet is particularly important to support both muscle growth and overall health.

Conclusion

Incorporating strength training into your weight loss plan while on GLP-1 medications can be a powerful strategy to boost metabolism, improve body composition, and support long-term weight management. By focusing on hydration, listening to your body, and ensuring proper nutrition, you can enhance the benefits of your workouts and help your body adapt to the changes brought on by GLP-1 medications.

Remember, strength training isn't just about building muscle; it's about increasing your overall strength, improving bone health, and achieving a balanced, functional body. Whether you’re just starting or looking to refine your existing routine, consistency, gradual progression, and professional guidance will set you on the right path.

Take action today by consulting with a healthcare provider to personalise your fitness plan, ensuring it aligns with your weight loss goals and medication regimen. Don't forget to hydrate, fuel your body with the right nutrients, and listen to your body's signals throughout your fitness journey. By making these adjustments, you’re setting yourself up for success, not just in weight loss, but in overall health and well-being.
