If you have diabetes and want to become more active, you may have wondered whether walking or other cardio exercises are better than strength training. You may also be wondering whether you really need to choose one over the other.
The good news is that you usually don't have to choose just one.
Cardio exercise and strength training offer different benefits, and both can have an important place in a diabetes-friendly exercise routine. Cardio can improve cardiovascular fitness and help your body use glucose during physical activity, while strength training helps build and maintain muscle and can support better glucose management.
So, instead of asking “Which exercise is better for diabetes?”, a more useful question is:
“How can I combine different types of exercise to support better health and blood sugar management?”
What Is Cardio Exercise?
Cardio, also known as aerobic exercise, involves continuous movement that increases your heart rate and breathing.
Common examples include:
- Walking
- Brisk walking
- Cycling
- Swimming
- Jogging
- Dancing
- Using an elliptical machine
- Water-based aerobic exercise
Walking is one of the easiest forms of cardio for many people because it does not require expensive equipment or a gym membership.
For someone who has been inactive, starting with short, comfortable walks and gradually increasing the duration can be a practical way to become more physically active.
Regular aerobic activity can support cardiovascular health, physical fitness, weight management and blood sugar control.
The key is consistency.
You don't necessarily need to begin with an intense workout. Building a routine that you can continue regularly may be more useful than exercising extremely hard for a few days and then stopping.
What Is Strength Training?
Strength training, sometimes called resistance training, involves making your muscles work against resistance.
The resistance can come from:
- Your own body weight
- Resistance bands
- Dumbbells
- Free weights
- Weight machines
- Other forms of resistance
Examples include squats, wall push-ups, lunges, resistance-band exercises and other controlled movements.
Strength training does not mean that you have to lift extremely heavy weights.
Beginners can start with simple movements and gradually increase the difficulty as their strength and confidence improve.
For people with diabetes, maintaining muscle strength can be particularly valuable because muscle plays an important role in movement, daily activities and glucose use.
How Cardio Exercise Can Help With Diabetes
Cardio exercise can provide several benefits for people living with diabetes.
When you walk, cycle, swim or perform another aerobic activity, your muscles need energy. Glucose is one of the fuels your body can use during physical activity.
Regular physical activity can also improve cardiovascular fitness and support healthy body weight.
Walking is especially convenient because it can be incorporated into everyday life.
For example, you could:
- Take a walk after a meal
- Walk while talking on the phone
- Take short walking breaks during the day
- Walk to nearby places instead of driving
- Gradually increase your walking speed or duration
You don't have to complete all your physical activity in one long workout.
Small amounts of movement throughout the day can also help reduce long periods of inactivity.
How Strength Training Can Help With Diabetes
Strength training provides a different type of physical challenge.
When your muscles work against resistance, they adapt by becoming stronger. Regular resistance exercise can help maintain muscle strength and physical function.
It may also support the body's ability to handle glucose effectively.
Another important benefit is muscle preservation.
As people age, maintaining muscle mass and strength becomes increasingly important for mobility, balance and independence. Adding resistance exercise to a regular activity routine can therefore provide benefits that walking alone may not provide.
This doesn't mean walking is less valuable.
It simply means that cardio and strength training work in different ways.
Cardio vs Strength Training: Is One Better?
This is where many people with diabetes become confused.
They may hear that walking is good for blood sugar and then hear that strength training is also beneficial.
So which one should they actually do?
The answer is that there is no single exercise that is best for everyone with diabetes.
Your ideal exercise routine depends on your current fitness level, age, health, medications, personal preferences and any diabetes-related complications.
For many people, combining aerobic activity with resistance training can provide a more balanced approach.
Cardio can help with cardiovascular fitness and overall activity, while strength training can help maintain and build muscle.
Together, they can cover different aspects of physical fitness.
Which Exercise Is Easier for Beginners?
For someone who is completely new to exercise, walking is often one of the simplest places to start.
You can control the pace, duration and distance, and you generally don't need special equipment.
Strength training can also be beginner-friendly when it starts with simple movements.
For example, a beginner might start with:
- Chair squats
- Wall push-ups
- Standing leg raises
- Light resistance-band exercises
- Gentle body-weight movements
The goal should be to learn proper movement rather than immediately trying to lift heavy weights.
As your fitness improves, the duration, frequency or resistance can gradually be increased.
Should You Choose Cardio or Strength Training?
If you enjoy walking but dislike gyms, there is no reason to abandon walking.
If you enjoy resistance exercises, you don't have to replace them with cardio.
And if you can comfortably include both, that may give you a more complete exercise routine.
The most important factor is whether the activity is appropriate for your health and something you can perform consistently.
Someone who currently does almost no physical activity may benefit greatly from simply becoming more active.
Someone who already walks regularly may benefit from adding strength training.
And someone already doing resistance exercises may benefit from adding regular aerobic activity.

Cardio vs Strength Training for Blood Sugar
Both cardio and strength training can influence blood sugar, but they do it in somewhat different ways.
During cardio activities such as walking or cycling, your muscles continuously use energy while you remain active. This can increase glucose use during and after exercise.
Strength training works your muscles against resistance. As your muscles become stronger and more active, regular resistance exercise can also support better glucose handling and overall metabolic health.
The response isn't exactly the same for everyone.
Your blood sugar can be influenced by:
- Exercise intensity
- Exercise duration
- Food intake
- Medication
- Starting blood glucose
- Fitness level
- Sleep and stress
- Individual metabolism
That's why one person may notice a different blood sugar response from the same workout performed by another person.
Which Is Better for Insulin Sensitivity?
Both forms of exercise can be useful.
Regular physical activity can help your body use glucose more effectively, while resistance training can help maintain and build muscle.
Muscle is an important tissue for glucose use, so maintaining healthy muscle mass becomes especially valuable as we get older.
This is one reason a combination of cardio and strength training can be more useful than focusing exclusively on one type of exercise.
You don't have to choose between:
Walking OR strength training
You can choose:
Walking AND strength training.
Which Is Better for Weight Management?
Both can contribute to a weight-management plan.
Cardio activities such as brisk walking, cycling and swimming can increase energy expenditure while improving cardiovascular fitness.
Strength training can help build or maintain muscle while supporting physical function.
For people trying to manage both diabetes and body weight, combining different forms of physical activity can provide a broader approach than relying on one exercise alone.
However, exercise is only one part of weight management.
Food choices, portion sizes, sleep, stress, medications and other factors can also influence your results.
Which Is Better for Heart Health?
Cardio exercise has an obvious connection with cardiovascular fitness because it challenges the heart and lungs over time.
Regular aerobic activity can help improve cardiorespiratory fitness and support cardiovascular health.
Strength training also has important health benefits and can contribute to overall physical fitness and metabolic health.
So again, it doesn't have to be a competition.
A routine that includes both can address different aspects of your health.
Which One Is Better for Building Muscle?
This is where strength training has the clear advantage.
Walking is excellent for general activity and cardiovascular fitness, but it doesn't provide the same resistance stimulus needed to build and maintain muscle strength.
Resistance exercises such as squats, rows, presses and other strength movements specifically challenge the muscles.
Maintaining muscle becomes increasingly important with age because loss of strength can affect:
- Balance
- Mobility
- Daily activities
- Ability to climb stairs
- Ability to carry groceries
- Independence
This is one reason strength training deserves a place alongside regular walking.
Can Walking and Strength Training Be Done on the Same Day?
Yes, depending on your fitness level and how you structure the workout.
For example, you could perform a short strength session and then take a comfortable walk.
Another option is to separate them:
Morning: Strength training
Evening: Walking
Or:
Monday: Strength training
Tuesday: Walking
Wednesday: Strength training
Thursday: Walking
There isn't one perfect schedule for everyone.
Your available time, fitness level and recovery all matter.
What Should Beginners Start With?
If you're currently doing very little physical activity, don't try to start everything at once.
You could begin with regular walking and then introduce two strength-training sessions each week.
For example:
Week 1
Short walks on several days.
Week 2
Continue walking and add two short strength sessions.
Week 3
Gradually increase walking duration or strength-training repetitions if you're comfortable.
This gradual approach can make exercise feel much more manageable.
How Long Should Cardio Sessions Be?
The general goal for most adults with diabetes is to build toward at least 150 minutes of moderate-to-vigorous aerobic activity per week, spread across at least three days.
You don't necessarily need to complete all of this in one session.
For example:
30 minutes × 5 days = 150 minutes
Or you could divide activity into shorter manageable periods throughout the day.
If you're currently inactive, start from your existing level and gradually increase your activity rather than trying to reach the full target immediately.
How Often Should You Strength Train?
For adults with diabetes, resistance exercise is generally recommended 2–3 times per week on nonconsecutive days.
This gives your muscles time to recover between sessions.
A beginner could start with two sessions per week and gradually build confidence and strength.
You don't need to train every muscle every day.
Recovery is part of the process.
Can You Use Walking as Your Cardio?
Absolutely.
Walking is one of the easiest forms of aerobic activity to incorporate into everyday life.
You can walk:
- After meals
- Before or after work
- During breaks
- Around your neighborhood
- On a treadmill
- In a park
- While doing everyday errands
You can also gradually increase your pace as your fitness improves.
This makes walking a particularly practical starting point for people who don't enjoy traditional gym-based cardio.
What If You Don't Like Strength Training?
You don't have to start with a gym.
Try simple movements at home.
For example:
Chair squats
Wall push-ups
Glute bridges
Calf raises
Resistance-band rows
Even a short beginner session can introduce resistance exercise into your routine.
As you become more comfortable, you can gradually increase the challenge.
The Best Approach May Be a Combination
If your health and fitness level allow it, combining cardio and strength training can give you the benefits of both.
Think of it this way:
Cardio → heart and cardiovascular fitness
Strength training → muscles and strength
Both together → a more complete exercise routine
The goal isn't to find one exercise that does everything.
It's to build a routine that supports your overall health and that you can continue for the long term.

A Simple Weekly Combination
Here's one example of how cardio and strength training can fit together:
Monday: Strength training + short walk
Tuesday: 25–30 minute walk
Wednesday: Strength training
Thursday: Walking
Friday: Strength training + short walk
Saturday: Longer comfortable walk
Sunday: Rest or gentle movement
This is only an example.
Your ideal schedule should depend on your current fitness, health conditions, recovery and daily routine.
How to Build a Routine You Can Maintain
Knowing that cardio and strength training are both useful is one thing. Turning that knowledge into a routine you can actually follow is another.
You don't need to create a complicated workout schedule.
A simple routine that fits your lifestyle is often easier to maintain than an ambitious plan that leaves you exhausted after a few days.
For example, you might combine walking with two or three strength-training sessions during the week.
The goal is to find a balance between activity, recovery and consistency.
Should You Exercise Every Day?
You don't necessarily need a hard workout every day.
Different days can include different levels of activity.
One day might involve strength training, while another could include a comfortable walk.
Some days may simply involve light movement and normal daily activities.
Rest and recovery are particularly important after resistance exercise because your muscles need time to recover from training.
Being physically active regularly doesn't mean every day has to be an intense workout.
What About Blood Sugar Before and After Exercise?
Physical activity can affect blood glucose differently from person to person.
The response can depend on:
- Your starting blood glucose
- Exercise type
- Exercise intensity
- Exercise duration
- What and when you last ate
- Insulin or other medications
- Your individual response to exercise
Some people may notice their blood glucose decreases after walking or other moderate activity.
More intense exercise, including demanding resistance workouts, can sometimes produce a temporary increase in glucose in some individuals.
This is one reason it is useful to understand your own response to different types of exercise rather than expecting the same result as someone else.
People using insulin or medications that can cause hypoglycemia may need individualized advice about blood glucose monitoring, food and medication around exercise.
Can Exercise Cause Low Blood Sugar?
Yes, particularly for people using insulin or certain glucose-lowering medications.
Exercise can increase glucose use by your muscles, and blood glucose may sometimes fall during or after activity.
Possible symptoms of hypoglycemia can include:
- Shaking
- Sweating
- Dizziness
- Weakness
- Hunger
- Confusion
- Feeling faint
If you experience symptoms of low blood sugar during exercise, stop exercising and follow the treatment plan recommended by your healthcare professional.
Repeated exercise-related low blood sugar should be discussed with your healthcare team.
Don't independently change prescribed medication simply because you have started exercising.
Are There Times When You Should Be More Careful?
Exercise plans may need to be modified for some people with diabetes.
Extra consideration may be necessary if you have:
- Diabetes-related nerve problems
- Foot ulcers or significant foot problems
- Eye complications
- Cardiovascular disease
- Kidney disease
- Balance problems
- Significant joint or mobility limitations
- Frequent hypoglycemia
This doesn't automatically mean you cannot exercise.
It means that the safest type, intensity and duration of activity may need to be individualized.
If you have significant diabetes-related complications or have been inactive for a long time, discuss your plans with your healthcare professional before beginning a demanding exercise program.
Don't Forget About Your Feet
Walking is an excellent form of cardio, but foot care deserves special attention for people with diabetes.
Wear comfortable, properly fitting footwear and check your feet regularly.
Look for:
- Blisters
- Cuts
- Redness
- Swelling
- Sores
- Areas of irritation
If you have reduced sensation in your feet, previous ulcers or significant circulation problems, seek professional advice about appropriate exercise and footwear.
Which Exercise Burns More Calories?
People often compare cardio and strength training based entirely on calorie burn.
Cardio can use a meaningful amount of energy during the activity, especially when performed for longer periods or at greater intensity.
Strength training has a different purpose. It challenges the muscles and helps maintain or develop strength.
But focusing only on calories can miss the bigger picture.
For diabetes management, exercise is not simply about “burning off food.”
Physical activity can also support:
- Cardiovascular fitness
- Muscle strength
- Mobility
- Physical function
- Glucose management
- Weight-management efforts
- Overall health
That is why choosing exercise based only on calorie numbers isn't necessary.
What About Exercise for Weight Loss?
If weight loss is one of your goals, both cardio and strength training can be useful parts of a broader plan.
Cardio can increase physical activity and energy expenditure.
Strength training can help maintain muscle while improving strength.
However, exercise alone doesn't determine body weight.
Nutrition, portion sizes, sleep, stress, medications and other factors can also influence weight.
Rather than searching for one “best fat-burning exercise,” focus on building habits you can sustain over time.
Cardio vs Strength Training: Quick Comparison
| Goal | Cardio | Strength Training |
|---|---|---|
| Cardiovascular fitness | Excellent | Helpful |
| Building muscle strength | Limited | Excellent |
| Increasing daily activity | Excellent | Helpful |
| Supporting glucose management | Helpful | Helpful |
| Improving physical function | Helpful | Excellent |
| Beginner-friendly | Yes | Yes, with appropriate exercises |
| Equipment required | Often none | Can be done with little or no equipment |
| Can be combined with walking | — | Yes |
The important takeaway isn't that one column “wins.”
The two forms of exercise complement each other.
Common Exercise Mistakes to Avoid
Doing Too Much Too Soon
Going from almost no activity to intense daily workouts can make it difficult to maintain your routine.
Build gradually.
Choosing Exercise You Hate
The “perfect” exercise isn't useful if you stop doing it after one week.
Choose activities you can realistically continue.
Doing Only Cardio
Walking is excellent, but appropriate resistance training can provide additional benefits for muscle strength and physical function.
Doing Only Strength Training
Resistance exercise is valuable, but aerobic activity remains an important component of overall fitness.
Ignoring Recovery
Your body needs time to recover, especially after challenging resistance workouts.
Ignoring Symptoms
Pain, unusual shortness of breath, dizziness, chest discomfort or other concerning symptoms shouldn't simply be pushed through.
Seek appropriate medical attention when necessary.
A Practical Weekly Exercise Plan
Here's one example of how someone might combine the two:
Monday
Strength training + short comfortable walk
Tuesday
30-minute walk or another aerobic activity
Wednesday
Light activity or recovery
Thursday
Strength training + short walk
Friday
30-minute cardio session
Saturday
Comfortable longer walk, cycling or another enjoyable activity
Sunday
Rest or gentle movement
This is only an example, not a personalized medical exercise prescription.
Your routine can be adjusted according to your fitness level, health, schedule and preferences.
What If You Only Have 20 Minutes?
You can still exercise.
For example:
10 minutes of strength exercises
10 minutes of walking
Or you could alternate days:
Monday → 20-minute walk
Tuesday → 20-minute strength session
A lack of a full hour doesn't mean exercise is pointless.
A realistic routine you repeat consistently can be more valuable than waiting for the perfect workout schedule.
