GLP-1 medications have become one of the most talked-about topics in health and fitness. You have likely heard names like Ozempic®, Wegovy®, Mounjaro®, or Zepbound® in conversations about weight management and diabetes.
With so much attention on these medications, one question keeps coming up:
If someone is taking a GLP-1 medication, do they still need to exercise?
The answer is yes.
Research increasingly shows that physical activity, particularly a combination of strength training and cardiovascular exercise, plays an important role in supporting overall health, preserving muscle mass, increasing bone health, and improving long-term outcomes while using these medications.
At Shred415, this is why we believe movement and strength training matters, regardless of where someone is in their health journey.
What Is a GLP-1 Medication?
GLP-1 stands for glucagon-like peptide-1, a hormone naturally produced in the body that helps regulate blood sugar and appetite.
GLP-1 medications mimic this hormone and may:
- Slow stomach emptying
- Increase feelings of fullness
- Help regulate blood sugar
- Reduce appetite
These medications are prescribed for certain individuals with obesity, overweight, and type 2 diabetes under the guidance of a healthcare provider.

Why Is Exercise Important While Taking a GLP-1?
Exercise provides benefits that medications alone cannot.
According to Healthline’s medically reviewed guide on GLP-1 medications and exercise, physical activity can help:
- Preserve muscle mass
- Support bone density
- Improve cardiovascular health
- Increase energy
- Improve mood and sleep
- Help maintain weight loss over time
Exercise is important for everyone, but maintaining muscle and strength becomes particularly important during significant weight loss because lean tissue can be lost alongside body fat.

Can You Lose Muscle While Taking a GLP-1?
Potentially, yes.
Research has shown that some of the weight lost while taking GLP-1 medications may come from lean body mass, which includes muscle tissue.
According to Cleveland Clinic endocrinologist Dr. Anira Iqbal:
“A combination of strength training and aerobic exercises really makes sure that what you’re losing is mostly fatty tissue.”
This is one reason healthcare professionals increasingly emphasize exercise as an essential component of long-term health management.
Can GLP-1 Medications Affect Bone Density?
One area receiving increasing attention from researchers is the potential impact of significant weight loss on bone health.
While GLP-1 medications can be effective tools for weight management when prescribed by a healthcare provider, rapid weight loss from any cause can place people at greater risk of losing bone mineral density if they are not engaging in regular exercise, particularly resistance training and weight-bearing activity.
Researchers are investigating the effects of GLP-1-associated weight loss on bone health, and some studies suggest maintaining strength training and weight-bearing exercise may be important for preserving bone mineral density during significant weight loss.
This is one reason many healthcare professionals recommend incorporating both strength training and cardiovascular exercise into a weight-management plan. While cardio supports heart health and endurance, resistance training places healthy stress on bones and muscles, encouraging the body to maintain strength and density.
To understand how resistance training supports long-term skeletal strength, explore why modern fitness is moving away from single-goal training.
Why Strength Training Matters for Bone Health
Most people think about strength training as a way to build muscle, but it also plays a critical role in maintaining healthy bones.
According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, weight-bearing and resistance exercises can help improve bone strength and reduce the risk of osteoporosis later in life.
Strength training can help:
- Maintain bone mineral density
- Support healthy aging
- Improve balance and stability
- Reduce the risk of falls and fractures
- Preserve lean muscle mass during weight loss
For individuals experiencing significant weight loss, preserving both muscle and bone becomes just as important as the number on the scale.

How Shred415 Supports Muscle and Bone Health
One reason strength training remains a core component of every Shred415 workout is because fitness is about more than calorie burn.
The strength-training intervals in class help challenge muscles and bones through resistance-based movements, while the treadmill intervals provide cardiovascular benefits. Together, this combination helps support:
- Muscle preservation
- Bone health
- Functional strength
- Cardiovascular fitness
- Long-term health and longevity
Whether someone is taking a GLP-1 medication or not, maintaining muscle and bone strength becomes increasingly important as we age.

What Are the Best Exercises While Taking a GLP-1?
There is no single “perfect” workout.
However, experts consistently recommend combining:
Strength Training
Strength training helps:
- Preserve muscle mass
- Support bone health
- Improve metabolism
- Maintain functional strength
Examples include:
- Bodyweight exercises
- Resistance bands
- Dumbbell exercises
- Functional strength movements
Cardiovascular Exercise
Cardio helps:
- Improve heart health
- Build endurance
- Support metabolic health
- Increase overall fitness capacity
Examples include:
- Walking
- Jogging
- Cycling
- Rowing
- High-intensity interval training (HIIT)
The CDC recommends adults aim for:
- At least 150 minutes of moderate-intensity aerobic activity each week
and - Muscle-strengthening activities on two or more days per week.
Is HIIT Safe While Taking a GLP-1?
There is no universal answer because every person’s medical history and fitness level are different.
However, HIIT can be an effective option for many individuals when appropriately scaled and approved by their healthcare provider.
HIIT combines periods of effort with recovery and can improve:
- Cardiovascular fitness
- Muscular endurance
- Exercise efficiency
- Overall conditioning
The key is progression.
Some people may need to begin with walking, lower-intensity intervals, or shorter workouts before gradually increasing intensity.
Why HIIT and Strength Training Work Well Together
Research consistently shows that combining resistance training and cardiovascular exercise produces benefits that neither type of exercise provides alone.
This combination helps support:
- Heart health
- Muscle preservation
- Bone health
- Functional fitness
- Long-term weight management
This integrated approach is also why modern fitness continues to move away from single-goal training and toward more balanced programming.
How Does Shred415 Fit Into This Conversation?
Shred415’s class format alternates between treadmill intervals and strength training throughout the workout.
This combination naturally incorporates:
- Cardiovascular conditioning
- Strength development
- Functional movement
- Interval-based training
- Workout variety
Importantly, every participant can walk, jog, or run at their own pace, and exercises can be modified to suit individual fitness levels.
Whether someone is taking a GLP-1 medication or not, maintaining strength, cardiovascular fitness, and consistent movement habits remains an important part of long-term health.
Why Exercise Matters Beyond Weight Loss
Exercise does far more than burn calories.
Regular movement supports:
- Heart health
- Bone density
- Mental wellbeing
- Sleep quality
- Energy levels
- Functional independence as we age
The goal should not simply be losing weight. It should be building a body that feels stronger, moves better, and supports health for years to come.
Frequently Asked Questions
What does GLP-1 stand for?
GLP-1 stands for glucagon-like peptide-1, a hormone involved in blood sugar regulation and appetite control.
Do you still need exercise while taking a GLP-1?
Yes. Exercise helps support cardiovascular health, preserve muscle mass, and improve long-term health outcomes.
What type of exercise is best while taking a GLP-1?
Most experts recommend combining resistance training and cardiovascular exercise.
Can you lose muscle while taking a GLP-1?
Research suggests that some lean body mass can be lost during significant weight loss, which is why strength training is often encouraged.
Can GLP-1 medications cause bone loss?
Research is ongoing, but experts generally agree that significant weight loss can contribute to reductions in bone mineral density if muscle and bone are not adequately stimulated through exercise. Strength training and weight-bearing activity may help reduce this risk.
