Yes, exercise helps with prediabetes, and it is one of the most effective ways to stop it from progressing to type 2 diabetes. Regular physical activity makes your body more sensitive to insulin and encourages your muscles to use glucose for energy, which lowers blood sugar during and after activity. The American Diabetes Association (ADA) recommends at least 150 minutes a week of moderate-intensity aerobic activity, such as brisk walking or cycling, plus two strength-training sessions a week. Any movement counts, and pairing exercise with healthy eating gives the best chance of bringing blood sugar back into the normal range.

Key Takeaways

• Prediabetes means blood sugar is higher than normal but not yet high enough to be diagnosed as type 2 diabetes. According to the CDC, more than 84% of people with prediabetes do not know they have it.
• Exercise lowers blood sugar in two ways: it increases insulin sensitivity, and working muscles take up glucose for energy during and after activity.
• The target is at least 150 minutes a week of moderate-intensity aerobic activity plus two strength-training sessions a week, as recommended by the American Diabetes Association.
• The best exercises for prediabetes are brisk walking, strength training, cardio such as swimming or cycling, yoga, and balance and flexibility work such as Tai Chi or Pilates.
• Start small and stay consistent: 10 minutes a day is a valid starting point, and three 10-minute walks work as well as one 30-minute walk.
• Exercise works best with diet changes: limiting processed foods, eating more fruits and vegetables, and controlling portions.

What is prediabetes?

Prediabetes means your blood sugar levels are higher than normal but not high enough to be diagnosed as diabetes. It is a health condition that often precedes type 2 diabetes, yet it's not quite as alarming as it sounds. Prediabetes is essentially a wake-up call. It's your body signaling that something needs to change – and fast.

This condition affects millions across the nation. In fact, according to the CDC, over 88 million American adults — approximately one in three — have prediabetes.

But here's where things get tricky: prediabetics aren't always aware they have this condition. The CDC reported that more than 84% of people with this condition don't know they have it, a finding covered in our article on how most prediabetics are unaware of their condition. That's because prediabetes often doesn't present any clear symptoms; learn what to watch for in our guide to prediabetes symptoms, diagnosis, and treatment.

It might seem scary at first glance but remember - knowledge is power. Identifying prediabetes early allows you to take control before it progresses further into type 2 diabetes.

What are the risk factors for prediabetes?

The main risk factors for prediabetes are:

• Family history of type 2 diabetes
• Overweight or obesity
• Lack of physical activity
• Age (especially after 45 years)
• Certain ethnic groups are more prone (e.g., African Americans, Hispanics/Latinos)

Understanding these risks can help us make the lifestyle changes necessary for preventing or delaying the onset of type 2 diabetes. Lack of physical activity is one of the risk factors you can change directly.

Can exercise reverse prediabetes?

Exercise can play a vital role in managing and even reversing prediabetes, because regular physical activity is one of the most effective ways to prevent progression from prediabetes to full-blown diabetes. Whether blood sugar returns fully to the normal range depends on the person, how early the change starts, and whether exercise is combined with diet changes and weight loss where needed. The American Medical Association has also highlighted the role of exercise, including interval training, in managing prediabetes.

How does exercise lower blood sugar in prediabetes?

Exercise lowers blood sugar in prediabetes by making the body more sensitive to insulin, the hormone that regulates blood sugar levels. When we engage in regular exercise, our cells are better able to use available insulin to take up glucose during and after activity. This means your body doesn't have to work as hard to process the sugar in your bloodstream. Read more about insulin resistance and improving insulin sensitivity.

But there's more. Exercise also helps lower blood sugar levels by encouraging your muscles to use glucose for energy. So not only are we burning calories and boosting our heart health, but we're also directly tackling high blood sugar – the core issue at hand with prediabetes. For the evidence on this effect, see our article on exercise lowering blood sugar.

Do light activities like walking count?

Light activities like brisk walking count and can have substantial benefits for people with prediabetes. Exercise does more than burn calories, and even simple lifestyle changes can make a difference:

• Park further from your destination and walk
• Take stairs instead of elevators (see why stair walking may improve insulin resistance)
• Stand while talking on the phone

How much exercise do you need for prediabetes?

Adults with prediabetes should aim for at least 150 minutes a week of moderate-intensity aerobic activity like cycling or fast walking, according to the American Diabetes Association (ADA). The ADA also recommends two sessions per week of strength training exercises. Experts recommend 30 minutes of brisk walking per day to effectively manage blood sugar levels, and if you find it challenging to carve out a continuous half-hour slot, breaking it down into ten-minute increments works just as well.

Understanding your body's response to exercise is key too. Monitoring blood glucose before and after workouts will help you adjust your routine as needed; our guide explains how much blood sugar drops after exercise.

What are the best exercises for prediabetes?

The best exercises for prediabetes are brisk walking, strength training, cardiovascular exercise, yoga, and balance and flexibility exercises. Exercise plays a key role in managing and even reversing prediabetes, and each of these activities helps keep your blood sugar levels in check in a slightly different way. For step-by-step routines, see our six exercises for people with diabetes.

Brisk walking

Walking is an excellent starting point for people with prediabetes. It's low-impact, easy on joints, and requires no special equipment except for a good pair of shoes. Experts recommend 30 minutes of brisk walking per day, in one session or in ten-minute increments.

Strength training

Strength training is another great way to take control of your health when dealing with prediabetes. Lifting weights or doing bodyweight exercises like squats and lunges helps build muscle mass, which improves insulin sensitivity and aids in glucose metabolism.

Cardio

Any form of cardiovascular exercise that gets your heart rate up is beneficial for prediabetes, whether it's swimming laps at the pool, biking around the neighborhood or participating in an aerobics class. Cardio workouts not only burn calories but also help lower blood sugar levels post-exercise.

Yoga

Yoga isn't just about flexibility; it's also an effective tool against prediabetes. Regular practice enhances glucose tolerance and reduces stress – both extremely beneficial for people with high blood sugar risk. Learn more about yoga for blood sugar control.

Balance and flexibility exercises

Balance and flexibility exercises like Tai Chi or Pilates improve stability and help prevent falls (a common issue among diabetics). They are a useful addition to any prediabetes routine.

Prediabetes exercise summary

Remember that consistency is key. Choose activities you enjoy to make the process more enjoyable and sustainable. Of course, make sure to consult your healthcare provider before starting a new exercise regimen.

How do you start exercising when you have prediabetes?

The easiest way to start exercising with prediabetes is to set small, achievable goals: begin with just 10 minutes of activity per day and gradually increase from there. We've often heard that exercise is a key component in managing prediabetes, but let's be honest, it's not always as easy as lacing up our sneakers and heading out the door. Starting an exercise program can feel intimidating, yet you'll soon notice your stamina building up.

What if exercise causes leg pain or fatigue?

If physical discomfort is holding you back, choose low-impact exercises like swimming or cycling, which are easier on the joints and muscles. Some people with prediabetes might experience leg pain or fatigue during exercise due to poor circulation. Leg pain that comes on with walking and eases with rest is worth mentioning to your doctor. Wear well-fitting shoes and socks, and check your feet after workouts for blisters or sores; our guide covers ways to care for diabetic feet.

How do you stay consistent?

The best way to stay consistent is to schedule your workouts like appointments in your calendar so they become non-negotiable parts of your day. Life can get busy and before we know it, our workout time has been eaten up by other commitments. The trick here is prioritizing your health, because without good health, everything else falls apart.

What should a prediabetes workout plan include?

An effective prediabetes workout plan should include both cardiovascular activities like walking or jogging and strength training exercises such as lifting weights or resistance band workouts. Here are some quick tips:

• Start slow and gradually increase your activity level
• Choose low-impact exercises if physical discomfort is an issue
• Make regular workouts a priority in your schedule
• Include both cardiovascular and strength training exercises in your routine

Here are some tips for incorporating exercise into a prediabetic lifestyle:

• Start slow: You don't need high-intensity workouts right away. Start with low-impact exercises like walking or swimming.
• Consistency is key: Aim for at least 150 minutes of moderate-intensity aerobic activity each week.
• Mix it up: Combine aerobic exercises (like running or biking) with resistance training (like weights or resistance bands), and add yoga for flexibility.

Remember, health is a journey not a destination – and we're here to support you every step of the way.

What diet changes work best with exercise for prediabetes?

Exercise works best for prediabetes when it is paired with healthy eating: limiting processed foods, eating more fruits and vegetables, and controlling portions. Exercise alone isn't enough! Pairing regular physical activity with healthy eating habits can be a game-changer for people living with prediabetes. With prediabetes, it's all about balance. We're not talking about becoming an Olympic athlete overnight. Instead, it's more about sustainable changes that improve your health in the long run.

Consider these dietary tips:

• Limit processed foods: They often contain hidden sugars and unhealthy fats.
• Eat more fruits and vegetables: These foods are rich in fiber which helps control blood sugar levels.
• Portion control is crucial: Too much food, even if it's healthy, can lead to weight gain and higher blood sugar levels.

Structured lifestyle programs that combine diet, activity and coaching are another option; read about diabetes prevention strategies and benefits.

When should you see a doctor about prediabetes and exercise?

You should see your doctor before starting a new exercise regimen, and again if exercise brings on symptoms you haven't had before. Living well with prediabetes doesn't mean you're on this journey alone. We recommend seeking support from healthcare professionals who understand your unique situation. They can provide personalized advice on diet and exercise tailored to meet your specific needs, and they can repeat your blood sugar tests to show whether your changes are working.

Contact your doctor promptly if you notice:

• Chest pain, pressure or unusual shortness of breath during activity
• Dizziness or feeling faint during or after exercise
• Leg pain or cramping that comes on with walking and eases with rest
• Blisters, cuts or sores on your feet that are slow to heal
• Symptoms such as increased thirst, frequent urination or blurred vision, which can mean blood sugar is rising

Frequently asked questions about prediabetes and exercise

What is the best exercise for prediabetes?

The best exercise for prediabetes is the one you will do consistently, ideally a combination of aerobic activity and strength training. Brisk walking is an excellent starting point because it is low-impact and needs only a good pair of shoes. Adding two strength-training sessions a week builds muscle, which improves insulin sensitivity.

Can exercise alone reverse prediabetes?

Exercise can play a vital role in reversing prediabetes, but exercise alone isn't enough for most people. Pairing regular physical activity with healthy eating habits, and weight loss where needed, gives the best chance of returning blood sugar to the normal range. Your doctor can confirm progress with repeat blood tests.

How many times a week should I exercise for prediabetes?

Most people with prediabetes should exercise on most days of the week, building up to at least 150 minutes of moderate-intensity aerobic activity weekly, such as 30 minutes on five days. Add strength training on two days a week. If you are just starting, 10 minutes a day is a reasonable first goal.

What is the best time to exercise for prediabetes?

The best time to exercise for prediabetes is a time you can stick to every day. Many people find a short walk after meals helpful because muscles use glucose for energy as blood sugar rises after eating. Read more about exercising after eating for blood sugar.

Why is my blood sugar still high even though I exercise?

Blood sugar can stay high despite exercise if diet, portion sizes, sleep, stress or other health factors are also raising it, or if the activity has not yet been sustained long enough to improve insulin sensitivity. Monitoring blood glucose before and after workouts helps you see how your body responds. If your numbers are not improving, ask your healthcare provider to review your plan.
