Exercise for Type 2 Diabetes and Prediabetes in Markham, What Actually Works

Summary

Movement is one of the best things that you can do if you have currently known that you have 'type 2 diabetes' and get anxious about that, it is one of the most useful things that you can do at home. Also just wear your shoes and start walking or doing static exercises.

So if you know about the exercise for type 2 diabetes and prediabetes in Markham. In easy language, or how to manage meals and diet that helps slow your blood sugar and how to stay safe if you take diabetes medicine this guide is for you. That help includes Oak Valley Health's diabetes education centre and supervised exercise with a Registered Kinesiologist. We follow the Diabetes Canada guidelines, and we tell you honestly where the research is strong and where it is still thin.

Key takeaways

Introduction

Picture this. You're in your doctor's office, and your A1C came back higher than you hoped. Your doctor says, "You need to exercise more." You nod and walk out to the parking lot. Then the questions hit. How much? Walking or lifting? Every day? What if I feel dizzy?

You're not alone, and the answers are simpler than you think. This guide explains what exercise does to your blood sugar, how much you need, how to start this week and how to stay safe. We built it for Markham, so it covers local risk, local places and local winters. It follows the Canadian guidelines from Diabetes Canada.

The short answer

You should build up your aerobic exercise each week, working toward the Diabetes Canada target of 150 minutes a week. Do strength training at home and brisk walks so you don't need to go to the gym. And try to keep doing these regularly and don't take a break for more than 2 days.

One more thing before you lace up. If you take insulin or a sulfonylurea, ask your healthcare provider how to avoid low blood sugar first. A quick chat now makes every walk safer.

How we built this guide, so you can trust it

Most diabetes exercise articles skip four things. They skip the higher risk in Markham's South Asian and Chinese communities. They skip the fact that Canada and the US use different A1C ranges. They give strength training one line instead of a real plan. And they skip the low blood sugar that can hit hours after a workout. We cover all four.

We wrote this guide from public sources that you can check, and we link them as we go. The exercise targets come from the Canadian clinical practice guidelines on physical activity and diabetes. The risk research comes from ICES, an Ontario health research institute, and the 2021 census from Statistics Canada. The local services come from Oak Valley Health and the City of Markham.

There is one more thing we want to clarify. This guide is not meant to replace your doctor's prescribed treatment plan, because the information here is based on trials and case studies drawn from many different people, so it reflects an average outcome, and your own result may vary based on your own body.

How exercise lowers blood sugar (and keeps working after you stop)

When you move, your muscles need fuel. They pull sugar, called glucose, out of your blood. They do it through tiny doors on muscle cells called GLUT4 transporters. These doors can open even when insulin isn't working well. That's why a walk can bring your numbers down fast.

Your body also protects you. Your muscles burn stored sugar called glycogen, and your liver adds more glucose when you need it. Two hormones, glucagon and epinephrine (also called adrenaline), tell the liver when to do that. For most people, this keeps blood sugar steady during a walk or a workout.

Here's the part many people miss. The benefit lasts. Diabetes Canada says exercise can lower your blood sugar for up to 48 hours, and its guidelines say your body stays more sensitive to insulin for about that long. Insulin sensitivity simply means how well your body listens to insulin. When it listens better, the same insulin does more work. Over time, your A1C, your three month blood sugar average, tends to drop. That's why the guidelines say not to leave more than two days between sessions. You're topping up a benefit that fades.

There are more benefits of regular exercise too. Your blood pressure tends to improve, and your cardiovascular health and heart get better over time, since diabetes is linked to these as well. Exercise also supports overall body development, and your sleep, mood, and confidence tend to improve.

Why Markham needs its own advice

Most diabetes articles quietly assume one kind of reader. Markham doesn't fit that. Chinese Canadians are the largest group in the city. South Asian Canadians are the second largest, at 17.6 percent of residents in the 2021 census.

That matters, and the ICES research shows why. South Asian, Chinese and Black adults in Ontario develop diabetes at lower body weights than white adults. Look at the BMI of 30, where white adults reach a given diabetes rate. South Asian adults reach the same rate at a BMI of 24. Chinese adults reach it at 25. After the researchers adjusted for age, sex, income and BMI, South Asian adults had a 3.4 times higher rate of new diabetes, and Chinese adults had a 1.9 times higher rate.

So if you look healthy on the scale and still worry, your worry makes sense. A normal BMI doesn't always mean low risk. Researchers also see a pattern in many South Asian adults, less muscle, more fat stored in the liver and stronger insulin resistance. Muscle helps your body handle sugar, which is why this guide gives strength training as much room as walking. To learn more about this pattern, read Exercise as Medicine, Diabetes Prevention for South Asians in the GTA.

A family history of diabetes can also raise your own risk. That is not a reason to worry quietly, it is a reason to ask your doctor for an A1C blood test, so you can find out whether prediabetes is present years before you feel anything.

Prediabetes and type 2 diabetes, two different conversations

Let's start with the numbers, because websites don't agree with each other. In Canada, prediabetes means an A1C of 6.0 to 6.4 percent. Many American sites say 5.7 to 6.4 percent, because the American Diabetes Association starts its range a little lower. Nobody made a typo. Type 2 diabetes begins at an A1C of 6.5 percent.

One honest caution. A1C is a helpful test, but it isn't perfect for everyone. Some health conditions can change how accurate it is, so your doctor may also check your fasting blood sugar or order another test. Your own result belongs in a talk with your doctor, not in a late night internet search.

If you have prediabetes, think prevention

Think of prediabetes as a smoke alarm, not a fire. It's a warning that gives you time to act. The Government of Canada's diabetes report says that not everyone with prediabetes develops type 2 diabetes, though many do. So this isn't a verdict. It's a head start.

Here's what the research says about using that head start. Clinical trials show that people who follow a disciplined routine of exercise and controlled diet see meaningfully better outcomes than those managing diabetes without that structure over the following years.

The Diabetes Care Community, a Canadian education site, says healthy eating, weight loss when needed and regular activity can cut the risk of moving from prediabetes to type 2 diabetes by almost 60 percent. So if you wonder how to delay or prevent type 2 diabetes, this is how.

What about exercise on its own? The Canadian guidelines cite research linking 150 minutes of moderate activity a week to a 26 percent lower risk of type 2 diabetes, and twice that amount to a 36 percent lower risk. These numbers come from studies that follow large groups, so they show a link, not a promise. The guidelines also point out that the biggest gains show up at low levels of activity. That means your first few walks do the heaviest lifting.

You're in good company, too. Beyond Type 2 Canada estimates that about 5.7 million adults in Canada have prediabetes.

If you have type 2 diabetes, think steady and safe

Living with type 2 diabetes gets better, but it takes time, this is not a one week or one month process. With proper exercise and diet control, kept up consistently, you can work toward better blood pressure and a healthier heart.

So how much can exercise lower your A1C? The Canadian guidelines describe a review of exercise programs for people with diabetes. Programs that added up to more than 150 minutes a week lowered A1C by about 0.9 percentage points on average. Programs of 150 minutes or less lowered it by about 0.4. You can read those numbers in the guidelines yourself.

Now the honest part. Those are averages across many people, so your own change could be bigger or smaller. Your medicine, your eating habits and how long you've had diabetes all play a part. A1C also moves slowly, because it reflects about three months of blood sugar. One great week of walking won't change it overnight. Please don't measure yourself against a number from a study. Measure yourself against where you started.

Here's what we hope you take away. More movement tends to help, and you can build up a little at a time. The guidelines also say smaller amounts of activity still bring some benefit, so a short walk is never wasted.

And one more thing, because it matters. If something new seems to be helping your diabetes, it is tempting to stop an existing medicine because you feel the exercise is doing the work instead. Please do not do that on your own. Any change like that should be a slow process, double checked with your existing doctor first, and only adjusted under their monitoring as your numbers actually improve.

How much exercise do you need? Think 150, 2 and 20

Here's a shortcut you can keep in your head. The Canadian guidelines for physical activity and diabetes boil down to three numbers.

150 is how many minutes of aerobic exercise to aim for each week, at a moderate to vigorous pace. Spread them over at least 3 days, and take no more than 2 days off in a row. Short walks count too, as long as each one lasts at least 10 minutes.

2 is the least number of strength sessions to do each week. Three is even better.

20 is a gentle nudge to stand up and move every 20 to 30 minutes when you've been sitting for a long time.

So what does "moderate" feel like? You can talk, but you couldn't sing. Say you walk briskly for 30 minutes on five days. That's 150 minutes, and you're done. Short on time? Split each 30 minutes into three 10 minute walks, one after each meal. Your body doesn't mind, and neither do the guidelines.

You're not on your own with these numbers, either. The Canadian 24 Hour Movement Guidelines for adults ask for the same 150 minutes a week, plus muscle strengthening at least twice a week. They also encourage several hours of light movement, like standing, and less sitting. So you can treat 150, 2 and 20 as the exercise guidelines for Canadians, whether or not you live with diabetes.

Exercise for diabetes chart, your quick guide

Think of your week as a mix of four kinds of movement. You don't need to master them all at once.

Aerobic exercise for diabetes, start with a walk

Good news first. You don't need a gym, a fancy watch or a perfect plan. A pair of supportive shoes and a safe path is enough. Walking for diabetes is the easiest way to begin, and it works just as well as walking for prediabetes. Brisk walking counts as moderate intensity exercise, which is the level the guidelines ask for. A simple way to check your pace is the talk test. If you can chat but couldn't sing, you're in the right zone.

Short walks count too. Diabetes Canada says several sessions of at least 10 minutes can add up to your weekly 150 minutes. So a walk before work, one at lunch and one after dinner is a real workout, not a cheat.

Do your knees or hips complain? Pick something kinder to your joints. Cycling is low impact, and so is swimming, so a stationary or recumbent bike, a lap pool or an aquafit class can all do the job. If you live in Markham, aquafit is part of a City fitness membership. Jogging and dancing are great too, once your body and your doctor agree.

Now, a promise to yourself, start low and slow. If you haven't exercised in a while, a Diabetes Canada summary for healthcare providers suggests a gentle ramp for people with very low fitness. Walk 5 minutes a day for a week, then 10 minutes a day, then 15, and keep building toward 150 minutes a week over six weeks or more. Nobody has to begin with a 45 minute power walk. Nobody.

Is weight loss part of your goal? Then be patient with yourself. The Diabetes Care Community says significant weight loss usually takes at least 250 minutes of exercise a week. Here's the encouraging part, a Cochrane review of controlled trials found exercise improved blood sugar control in people with type 2 diabetes even without weight loss. So your numbers can start to move before the scale does.

A few safety notes, because you deserve a safe start. If you take insulin or a sulfonylurea, ask your healthcare provider how to prevent low blood sugar before you lengthen your walks. If your feet feel numb or you've had sores, check them after every walk. And if anything feels wrong, like chest pain or dizziness, stop and get help.

Resistance exercise for diabetes, the habit most people skip

Let's be honest. Has anyone ever looked forward to a set of lunges? Probably not, and that's why strength training is the part of the plan most people skip. Walking feels friendly. Weight training feels like homework.

So why bother? Because your muscles do a lot of the work when it comes to blood sugar. Muscle is a major place your body stores and burns glucose, and it's where much of insulin resistance shows up. When you build muscle mass, you give your body more room to use blood glucose. That supports better insulin sensitivity and glycemic control, which just means steadier blood sugar. Strength work can also support your bones, muscle strength and physical function, so carrying groceries or climbing stairs feels easier.

You don't need a barbell or a gym membership. Resistance exercise means working your muscles against a load. That load can be weights, weight machines, resistance bands or your own body weight. Diabetes Canada's guidelines recommend resistance training at least twice a week, and they say three times is even better. That advice includes older adults. Diabetes Canada also shares resistance exercise videos, so you can see the moves before you try them.

What about prediabetes? Strength training is a smart addition there too, next to your walking. Ask your healthcare provider to include it in your plan. If you're unsure where to begin, a qualified exercise specialist can set your starting point and keep your joints, heart and medicines in mind.

A beginner session you can try

First, a quick note. The numbers below are a common starting point for beginners, not a prescription made for you. Diabetes Canada tells us how often to do resistance exercise. The exact exercises, sets and reps come from standard beginner practice, so treat them as a friendly draft. Your healthcare provider, diabetes educator or exercise specialist can adjust them for your joints, your heart and your medicines.

Here's the plain version. Pick 6 to 8 exercises that train your major muscle groups, arms, chest, back, legs and abdomen. Do each move 8 to 12 times. That's one set. Rest for 1 to 2 minutes, then go again. Start low and slow. If you're new, stay with one set for the first week or two. Add a second set when it feels easy, and work up to three.

• Chair squats, sit down slowly, then stand back up using your legs.
• Wall push ups, stand an arm's length from the wall and press away. Move to the kitchen counter, then the floor, as you get stronger.
• Step back lunges, rest a hand on the counter for balance, step one foot back, then return. Switch legs.
• Band rows, pull a resistance band toward your ribs and squeeze your shoulder blades together.
• Plank, start on your knees, then try your toes. It builds core strength too.
• Stair climbing or step ups, take one step at a time and hold the rail.
• Mountain climbers are the advanced move. Save them until your healthcare provider says vigorous exercise is safe for you.

How to stay safe while you build strength

• Warm up. Walk for 5 minutes first.
• Move slowly. Smooth, controlled reps beat fast, jerky ones.
• Keep breathing. Breathe out as you push or lift. Don't hold your breath.
• Know tired from hurt. Warm, tired muscles are normal. Sharp pain, joint pain, chest pain or dizziness means stop.
• Rest between sessions. Take at least one day off between strength days.
• Plan for low blood sugar. If you take insulin or a sulfonylurea, check your blood sugar around workouts and keep fast acting carbohydrate nearby.
• Check in first if needed. Talk with your provider if you have joint pain, diabetes related eye problems, or heart or blood pressure concerns.

No gym? No problem

Live in a condo with no equipment? You can still do almost everything above. Your stairwell works for stair climbing and step ups. A backpack with a few books adds weight to squats. One resistance band covers the rows and plenty more.

And a gentle reminder. Muscle builds slowly, over weeks and months, not days. If the first sessions feel awkward, that's normal. Write down what you did, and notice how much easier it gets.

Walking after meals, exercise snacks and how to sit less

If you add only one habit from this whole guide, make it a short walk after you eat. A 2023 review in Sports Medicine pooled studies in healthy adults and people with impaired glucose tolerance. It found that walking works better when you start soon after a meal than when you wait or walk before eating. A 2022 review in the same journal found that even 2 to 5 minutes of light walking, repeated through a long sitting day, softened the blood sugar rise compared with sitting.

A simple goal is 10 minutes after each main meal. In Markham, that could mean a lap of your condo hallway, a stroll around the block after dinner or a few rounds on a community centre track.

No time? Try exercise snacks. These are tiny bursts of movement sprinkled through your day, and Diabetes Canada uses the term itself. Do 10 squats while the kettle boils. Take two flights of stairs after a call. March in place during a TV ad. They add up faster than you'd think.

And about sitting. Long, unbroken sitting is hard on blood sugar. Here's how to sit less and move more. Set a phone timer to stand every 20 to 30 minutes. Take phone calls on your feet. Park a little farther away. Put your walk in your daily calendar like a meeting. Wear a pedometer, accelerometer or step monitor, so you can watch your day add up.

HIIT and interval training, the short, sharp option

You don't need to sprint like a track star. A gentle start is interval walking, 3 minutes of faster walking, then 3 minutes of slower walking, repeated for 20 to 30 minutes.

High intensity interval training, or HIIT, turns the dial up. You push near your maximum for 30 seconds to 1 minute, then recover at an easy pace for 1 to 3 minutes. HIIT for prediabetes and HIIT for type 2 diabetes can work for some people, so talk with your doctor first. Very hard effort can also push blood sugar up for a while afterward, so watch how your own body responds.

Tai chi, qigong, yoga, Pilates and dance

Not everyone loves a treadmill, and that's fine. Movement you enjoy is movement you'll keep doing.

Tai chi gets plenty of attention, so here's the honest picture. A 2022 review of controlled trials found tai chi improved HbA1c compared with usual care, but it didn't clearly beat other kinds of exercise. A 12 week trial in middle aged and older adults saw HbA1c rise in the tai chi group, and the authors urged caution for people with central obesity. So tai chi and qigong can support balance, calm and quality of life. They fit best next to walking and strength work, not in place of them.

Yoga and Pilates add flexibility, posture, range of motion and core strength. Stretching, meditation and breathing practice can also help you relax. Dance is another good option. The Armadale Older Adults Club lists yoga, chair yoga and Bollywood style dance, and other city clubs run wellness classes too.

A sample week in Markham

Here's a week you can copy, then bend to fit your life.

If you have prediabetes

That adds up to about 155 minutes of aerobic activity and two strength sessions.

If you have type 2 diabetes and take medicine

Use the same week, and add four habits for the first two weeks.

• Check your blood sugar before and after new workouts with your meter or CGM.
• Keep fast acting carbohydrate with you.
• Ask your provider how to time exercise around meals and medicines.
• Skip hard sessions on days you feel sick, dehydrated or unusually weak.

When winter hits

Move your walks to an indoor track at the Aaniin, Cornell or Thornhill fitness centres. Swap one outdoor walk for an aquafit class. If you walk outside, wear boots with good grip.

Exercise safety tips for diabetes

Please read this section twice. It makes everything else safer.

A quick word on type 1 diabetes

This guide focuses on type 2 diabetes and prediabetes. Type 1 plays by different rules, because the body makes little or no insulin. Questions like exercise with type 1 diabetes, fasted exercise, glucose swings during hard training and insulin changes need a plan built for you. An international consensus statement on exercise in type 1 diabetes, published in The Lancet Diabetes & Endocrinology in 2017, covers these topics in depth. Review it with your diabetes team before you change your routine.

How to start and how to stay motivated to exercise

Starting is the easy part. Staying is the real challenge, and a few habits help most people.

Pick small, attainable goals. Ten minutes after dinner beats a 60 minute plan you quit by Thursday. Build a support network. Tell your family, a friend or your doctor what you plan to do. Add accountability. Join a walking or running group, or promise a friend a weekly check in. Track your wins. Use a pedometer, accelerometer or step monitor, and put your walks in your daily calendar. Choose what you enjoy. Dance, swim, walk with music or take the family to a trail on the weekend. Get a guide. A personal trainer or kinesiologist can set your starting point and adjust it as you get stronger.

If you miss a day, or even a week, you haven't failed. Pick it back up tomorrow.

Where to move in Markham

You have more options than you might think. The City of Markham runs five fitness centres, Aaniin, Centennial, Cornell, Markham Pan Am and Thornhill. A City fitness membership includes three indoor walk and run tracks, aquafit classes, public lane swims and group fitness classes. Indoor tracks are a lifesaver in a Markham winter. Check the City's site for current prices and schedules.

The City also partners with five older adult clubs. The Markham Seniors Activity Centre at 22 Water Street serves adults 55 and older. The Armadale, Milliken and Thornhill clubs run wellness and exercise classes too. The Markham YMCA near Unionville GO Station also has a fitness centre, group classes and aquatics, so confirm its hours and membership options before you visit.

Where to get diabetes care in Markham

Exercise works best next to good medical care, and Markham has a solid option. The Adult Diabetes Education Centre at Oak Valley Health serves adults who are at risk of diabetes, have prediabetes, or live with type 1 or type 2 diabetes. Its team includes endocrinologists, nurse educators and dietitian educators. They offer one on one visits and group sessions on healthy eating, active living and blood sugar monitoring.

You'll find it at Markham Stouffville Hospital (379 Church Street) and at the Aaniin Community Centre clinics (5665 14th Avenue). Services are by appointment only, so call (905) 472-7527 to ask how to book and whether you need a referral.

Where a Registered Kinesiologist can help

Your medical team looks after your medicine, food and monitoring. Many people still want help with the exercise part, and that's where a kinesiologist comes in. The Ontario Kinesiology Association has recommended adding Registered Kinesiologists to Ontario's diabetes education teams, so patients can get personal, supervised exercise programs.

If you'd rather skip the commute, a Progress+ Registered Kinesiologist can coach you at home. Read about our In-Home Personal Trainer in Markham service or explore our Diabetes and Metabolic Health program. Not sure whether you need a kinesiologist or a trainer?

Conclusion

If you take only one thing from this guide, let it be this, you don't have to do everything at once. Exercise for type 2 diabetes and prediabetes isn't about punishing workouts or perfect weeks. It's a walk after dinner, a couple of strength sessions, and showing up again tomorrow when you miss a day.

Here's what we hope sticks. Exercise helps your body use blood sugar and keeps your insulin sensitivity higher for up to two days afterward. The Canadian guidelines give you clear targets, 150 minutes of aerobic exercise a week and at least two strength sessions. And in a city as diverse as Markham, your own risk may look different from what generic advice assumes. That's a good reason to stay curious and ask questions.

Please keep your healthcare provider close as you begin. Share your plan, ask about your medicine and check your blood sugar when it makes sense. Safety isn't a speed bump. It's what lets you keep going for years. Lean on your support network too, whether that's a walking buddy, your family, a diabetes educator or a kinesiologist.
