Mounjaro and exercise

Can you exercise on Mounjaro?

Many people can stay active while using Mounjaro, but the right level of activity depends on your health, fitness level, treatment response and any side effects. Start gradually and speak to a healthcare professional if you have medical conditions, symptoms or concerns.

Gastrointestinal side effects such as nausea, vomiting and diarrhoea can be more noticeable during dose escalation and often reduce over time. Other symptoms, including dizziness, can also affect your ability to exercise.

Can you lose weight on Mounjaro without exercise?

It is recommended that you make healthy lifestyle choices when taking Mounjaro, which includes increased exercise.

For weight management, tirzepatide can reduce appetite and food intake. It is used alongside a reduced-calorie diet and increased physical activity. Strength activities can also support muscle strength and function.

Best types of exercise on Mounjaro

Regular exercise is important if you are on Mounjaro. If you do not already follow a regular exercise plan it might be easiest to start with a low-impact, shorter exercise that you can repeat multiple times a day (such as a brisk walk or some light stretching). Other useful exercises can include:

• Low-impact cardio: Swimming, cycling

• Gentle strength training: Can include resistance bands, light weights, bodyweight exercises, chair-based exercises, carrying shopping, yoga, pilates or other movements that are safe for you

• Yoga and pilates: Help with mobility, balance and core strength

When is the best time to exercise on Mounjaro?

There isn’t a single ‘best’ time to exercise on Mounjaro as everybody reacts to weight loss treatment differently.

Timing your exercise routine on Mounjaro will depend on how you react to your weekly dose. If you experience side effects like fatigue after your injection, choose a time to exercise when you feel well enough to do so. If you feel nauseous, dizzy, unusually tired or unwell, wait until symptoms settle or choose a gentler activity.

If you have diabetes, especially if you use insulin or sulfonylureas, ask your clinician how exercise may affect your blood sugar and what symptoms to look out for.

Should you wait after you’ve taken a Mounjaro injection to exercise?

There is no set waiting time after taking Mounjaro before exercising, but it is sensible to listen to your body. If you feel nauseous, dizzy, unusually tired or unwell, wait until symptoms settle and choose a gentler activity.

If you have vomiting or diarrhoea, take extra care to stay hydrated. Seek medical advice if symptoms are severe, persistent, or you are struggling to keep fluids down.

Building a diet and exercise routine on Mounjaro

Evidence from weight-management research generally supports combining dietary changes with physical activity for long-term weight management. Your clinician can advise what is appropriate for you. Incorporating this into your weight loss treatment routine can help you achieve and maintain results.

Start with small, sustainable choices that can fit into your everyday routine, such as:

• Cut down on high-fat or overly processed foods

• Increase fresh fruits and vegetables, proteins and whole grains

• Find opportunities to walk or be active around the house

• Start with small exercises and gradually build up an exercise regimen

Exercise plans for medicated weight loss

As outlined by the NHS, adults should aim to (at least):

• Do at least 150 minutes of moderate intensity activity a week or 75 minutes of vigorous intensity activity a week

• Do strengthening activities that work all the major muscle groups (legs, hips, back, abdomen, chest, shoulders and arms) on at least 2 days a week

In order to achieve this while on your weight loss journey it can be helpful to put together a fitness routine or exercise plan. While this can seem daunting if you’re a beginner, keep the following in mind:

• Set goals that provide a clear roadmap for your fitness journey

• Find a physical activity that you enjoy - whether you’re visiting your local swimming pool or joining a local sports team or running club

• Keep hydrated throughout

• Warm up before a workout and cool down after

A typical exercise plan could involve activities like walking, strength training or flexibility work such as yoga or pilates. If you’re worried about becoming tired or ‘hitting your limit’, remember you can start small and gradually increase your weekly exercise.

How Mounjaro side effects can affect exercis

Some of the common side effects of weight loss treatment - such as nausea, dizziness or fatigue - can affect how easy it is to exercise, particularly for higher-intensity workouts. If you’re experiencing some of these side effects while exercising, the following lifestyle tips could help:

• Stay hydrated

• Exercise less intensely if you’re feeling weak or tired

• Try smaller, regular meals - with plain foods if you’re feeling nauseous

• Get into good sleep habits

• Talk to a healthcare professional if you are experiencing side effects on a new dose (or existing side effects have become worse)

When to speak to a clinician

Talk to a healthcare professional if:

• You have any questions about your treatment or routine management

• You need advice on lifestyle changes or your dose

• Your weight loss has significantly slowed down or stopped

Seek urgent medical help if you develop severe, persistent stomach pain that may spread to your back, with or without nausea or vomiting, as this could be a sign of pancreatitis. Call 999 or go to A&E if the pain is severe or you feel seriously unwell.

FAQs

How do you build muscle while taking Mounjaro?

If you’re looking to build muscle, it’s recommended that you try regular strength training several times per week, making sure to target different muscle groups with each session.

Eating protein-rich foods such as fish, lean meats, eggs and tofu can also help to grow and repair muscles.

Can you run if you take Mounjaro?

Running can count towards the NHS recommendation of at least 150 minutes of ‘moderate’ intensity activity per week, or 75 minutes of ‘vigorous’ intensity activity a week, depending on intensity.

If you are new to running, start gradually with short distances or use programmes like Couch to 5K. If you start to feel nausea or fatigue, alternate between walking and running.
